Sean throws a baseball at an angle of 25 relative to the ground at a speed of 23m/s. What is the maximum height the ball will achieve? How long will it be in the air? How far away does Kelly need to be to catch the ball?

Answers

Answer:

To solve this problem, we can use the equations of motion for projectile motion:

- Vertical displacement: Δy = v₀sinθt - 1/2gt²

- Vertical velocity: v = v₀sinθ - gt

- Time of flight: T = 2v₀sinθ/g

- Horizontal displacement: Δx = v₀cosθt

where v₀ is the initial speed, θ is the angle of projection, g is the acceleration due to gravity (9.81 m/s²), t is the time of flight, and Δy and Δx are the vertical and horizontal displacements, respectively.

First, we can find the maximum height by using the equation for vertical displacement:

Δy = v₀sinθt - 1/2gt²

At the maximum height, the vertical velocity is zero, so we can find the time of flight by setting the vertical velocity equation to zero:

v = v₀sinθ - gt = 0

Solving for t, we get:

t = v₀sinθ/g

Substituting this into the equation for vertical displacement, we get:

Δy = v₀sinθ(v₀sinθ/g) - 1/2g(v₀sinθ/g)²

Simplifying, we get:

Δy = (v₀²sin²θ)/(2g)

Substituting the given values, we get:

Δy = (23²sin²25)/(2*9.81) ≈ 29.4 m

So the maximum height is approximately 29.4 meters.

Next, we can find the time of flight using the equation for time of flight:

T = 2v₀sinθ/g

Substituting the given values, we get:

T = 2*23*sin25/9.81 ≈ 3.5 s

So the time of flight is approximately 3.5 seconds.

Finally, we can find the horizontal displacement using the equation for horizontal displacement:

Δx = v₀cosθt

Substituting the given values, we get:

Δx = 23*cos25*3.5 ≈ 64.3 m

So Kelly needs to be approximately 64.3 meters away to catch the ball.

What is the critical angle between polycarbonate (n1 = 1.58) and quartz (n2 = 1.41)?

24 degrees
46 degrees
63 degrees
75 degrees

Answers

Answer:

Approximately [tex]63.2^{\circ}[/tex].

Explanation:

The refractive index [tex]n[/tex] gives the ratio between the speed of light in vacuum and the speed of light in the given material. A larger refractive index means slower speed of light in the medium. In this question, the speed of light is slower in polycarbonate than in quartz.

When light travels from a material of low light speed to a material of higher light speed, the angle of refraction [tex]\theta_{r}[/tex] will exceed the angle of incidence [tex]\theta_{i}[/tex] (both with respect to the normal.)

The critical angle at this interface is the [tex]\theta_{i}[/tex] for which [tex]\theta_{r} = 90^{\circ}[/tex]. Note that since [tex]\theta_{i}\![/tex] cannot exceed [tex]90^{\circ}[/tex], [tex]\theta_{i} < \theta{r}[/tex] and light must be entering a faster medium from a slower medium. In this question, light would be entering quartz ([tex]n = 1.41[/tex], faster) from polycarbonate ([tex]n = 1.58[/tex], slower.)

By Snell's Law:

[tex]n_{i}\, \sin(\theta_{i}) = n_{r}\, \sin(\theta_{r})[/tex],

Where:

[tex]n_{i}[/tex] is the refractive index of the medium from which light enters, [tex]n_{r}[/tex] is the refractive index of the medium light enters into,[tex]\theta_{i}[/tex] is the angle of incidence at which light enters the interface (with respect to the normal), and[tex]\theta_{r}[/tex] is the angle of refraction at which light leaves the interface (also with respect to the normal.)

Set [tex]n_{i} = 1.58[/tex] (polycarbonate), [tex]n_{r} = 1.41[/tex] (quartz), and [tex]\theta_{r} = 90^{\circ}[/tex]. Rearrange the equation and solve for [tex]\theta_{i}[/tex]:

[tex]\begin{aligned}\sin(\theta_{i}) &= \frac{n_{r}\, \sin(\theta_{r})}{n_{i}} \end{aligned}[/tex].

[tex]\begin{aligned}\theta_{i} &= \arcsin\left (\frac{n_{r}\, \sin(\theta_{r})}{n_{i}} \right) \\ &= \arcsin \left(\frac{1.41\, \sin(90^{\circ})}{1.58}\right) \\ &\approx 63.2^{\circ}\end{aligned}[/tex].

How can it be possible for two such different molecules to yield substances with the same boiling point? Describe the kinds of intermolecu attractions that must be involved and any other properties of the molecules that could cause this result.

Answers

Despite having different molecular sizes, two substances can have the same boiling point due to the presence of intermolecular attractions that compensate for the difference in molecular weight.

What is the explanation for the above response?

Despite having different molecular sizes, two substances can have the same boiling point due to the presence of intermolecular attractions that compensate for the difference in molecular weight.

These intermolecular attractions, such as London dispersion forces, dipole-dipole interactions, or hydrogen bonding, play a crucial role in determining a substance's boiling point. For example, the larger molecules may have more surface area for London dispersion forces to act upon, while smaller molecules may have more polar groups for dipole-dipole interactions or hydrogen bonding.

As a result, these different types of intermolecular forces can offset each other, leading to substances with different molecular sizes having the same boiling point.

Answers

Answer:

Melting Point = -50 °C

Boiling Point = 50 °C

Explanation:

A heating curve displays a substance in its 3 states.

On the graph, each region where the slope is positive represents the substance as a solid, liquid, or gas.

When the slope is 0, this is the temperature point at which the substance's state of matter has changed (i.e., melting or boiling/vaporization point) – also known as a phase transition. Essentially, the 0 slope regions are where the substance is changing from one state of matter to the next.

(When the substance is being heated, it's absorbing energy, but when it reaches a phase transition point, the substance begins to consume energy to change its matter state. That's why the temperature doesn't go up while the substance's internal Energy increases.)

In (Figure 1), where 'x' is Energy (J) and 'y' is Temperature (°C):

Region A (0 J ≤ x ≤ 200 J):

The slope is positive, so the substance is in a constant matter state. Because it's the first sloped region, the substance is in its solid state from -100 °C to -50 °C.

Region B (200 J ≤ x 600 J):

The slope is 0, so the substance has reached a phase transition point. Because the previous region was when the substance was solid, that means that the temperature throughout Region B is the melting point at -50 °C.

Region C (600 J ≤ x ≤ 800 J):

The slope is positive so the substance is in a constant matter state. We've already identified when the substance was solid and when it melted, so now the substance is in its liquid state from -50 °C to 50 °C.

Region D (800 J ≤ x ≤ 900 J):

The slope is 0, and since the previous region was when the substance was a liquid, it's now reached its boiling point at 50 °C.

Region E (900 J ≤ x ≤ 1000 J):

The slope is positive, and we've previously identified all of the transition points and matter states except for one, so the substance is now in its gaseous state after reaching 100°C.

(Once a substance reaches its gaseous state, the Temperature/Energy ratio is constant.)

A boy of mass 60 kg and a girl of mass 40 kg are together and at rest on a frozen pond and push each other apart. The girl moves in a negative direction with a speed of 3 m/s. What must be the final momentum of the boy?
A. 100 kgm/s
B. 120 kgm/s
C. -120 kgm/s
D. 40 kgm/s

Answers

Answer:

B. 120 kgm/s

Explanation:

The initial momentum of the system is zero since the boy and the girl are at rest. When they push each other apart, the total momentum of the system remains conserved. Since the girl moves in a negative direction, the boy must move in the positive direction with the same momentum to keep the total momentum of the system zero.

Let's assume the final momentum of the boy is p. According to the law of conservation of momentum,

(initial momentum) = (final momentum)

0 = p + (-40 kg)(-3 m/s)

0 = p + 120 kg m/s

p = -120 kg m/s

Therefore, the final momentum of the boy must be 120 kg m/s in the positive direction, which is answer choice B.

Ans

According to the law of conservation of momentum, the total momentum of the system before and after the interaction must be equal. Initially, the momentum of the system is zero since the boy and the girl are at rest. When they push each other, the girl moves in the negative direction with a speed of 3 m/s. Let's assume that the boy moves in the positive direction with a speed of v m/s.

The total initial momentum of the system is:

P_initial = m_boy * 0 + m_girl * 0 = 0

The total final momentum of the system must also be zero since there are no external forces acting on the system. Therefore:

P_final = m_boy * v + m_girl * (-3) = 0

where m_boy = 60 kg, m_girl = 40 kg, and v is the final speed of the boy in m/s.

Solving for v, we get:

60v - 120 = 0

v = 2 m/s

Therefore, the total final momentum of the boy must be:

P_final = m_boy * v = 60 kg * 2 m/s = 120 kg m/s.

So, the total final momentum of the boy must be 120 kg m/s.

Why might earthquakes be much more intense closer to the initial disturbance than they are further away

Answers

Answer:

Earthquakes are typically more intense closer to the initial disturbance because the seismic waves generated by the earthquake lose energy as they travel through the Earth's crust. The energy of the seismic waves is dissipated as they encounter different layers of rock and other materials, causing the waves to become weaker and less intense.

Closer to the initial disturbance, the seismic waves encounter less material to pass through, and therefore experience less energy loss. As a result, the waves are more intense and can cause more damage to structures and the surrounding environment.

In addition to this, the type of rock and soil that the seismic waves pass through can also affect their intensity. Softer materials like sand and clay amplify the seismic waves, which can cause more damage in the nearby areas.

Therefore, the distance from the initial disturbance and the geological features of the region can both affect the intensity of an earthquake. Typically, the closer an area is to the epicenter of an earthquake, the more intense the shaking will be, and the further away an area is, the weaker the shaking will be.

A 0.530-kg cart moving at 0.572 m/s to the right collides elastically with a 0.25-kg cart initially at rest. The 0.25-kg cart then moves off rapidly and compresses a spring before the 0.530-kg cart can catch it again.

Answers

To solve this problem, we can use the conservation of momentum and the conservation of kinetic energy.First, let's find the velocity of the 0.530-kg cart after the collision. We can use the conservation of momentum:m1v1 + m2v2 = m1v1' + m2v2'where m1 and v1 are the mass and velocity of the 0.530-kg cart before the collision, m2 and v2 are the mass and velocity of the 0.25-kg cart before the collision, and v1' and v2' are the velocities of the carts after the collision.Plugging in the numbers, we get:(0.530 kg)(0.572 m/s) + (0.25 kg)(0 m/s) = (0.530 kg)v1' + (0.25 kg)v2'Solving for v1', we get:v1' = [(0.530 kg)(0.572 m/s) + (0.25 kg)(0 m/s)] / (0.530 kg + 0.25 kg) = 0.378 m/s to the rightSo the 0.530-kg cart moves off to the right at 0.378 m/s after the collision.Next, let's find the maximum compression of the spring. We can use the conservation of kinetic energy:(1/2)m2v2^2 = (1/2)kx^2where k is the spring constant and x is the maximum compression of the spring.We know the mass and velocity of the 0.25-kg cart before the collision (v2 = 0 m/s), so we can solve for k:k = 2(1/2)m2v2^2 / x^2 = m2v2^2 / x^2Plugging in the numbers, we get:k = (0.25 kg)(0 m/s)^2 / x^2 = 0This means that the spring constant is 0, which is not physically possible. Therefore, there must be an error in the problem statement or some missing information that would allow us to calculate the maximum compression of the spring.

Let x = dist. from pivot to the 10N ↓ force

CCW rotation is +

CW rotation is -

(100 N)(3 m) - (10 N)(x) - (40 N)(L) = 0

300 N·m - (10 N)(x) - (40 N)(L) = 0      divide by 10 on both sides

30 - x - 4L = 0

x + 4L = 30

10N is the Weight of the beam, so it is at the midpoint of the beam.

x = 5 - 3 = 2 m  substitute into the equation above:

Evaporation;

Condensation

Precipitation

Sublimation

Runoff

Infiltration

The arrangement of the materials is as follows;

Place the glass jar (the lake) containing water and the lamp (the Sun) side by side, such that the lamp light shines on the water surface

Cover the glass jar by wrapping the plastic wrap (the sky) around it to prevent the escape of water vapor when the water is hot.

Switch on the lamp so that it heats the water by radiation heat transfer

Observed processes;

The processes demonstrated by the above experiment includes;

1) Evaporation: As the water in the glass jar becomes warmer, the level of the water in the jar can be observed to decrease slightly due to evaporation

2) Condensation: Fog formation, Clouds

When hotter, the water surface as seen through the clear plastic wrap becomes less clearer due to evaporation, and condensation of the vapor while floating above the water surface, similar to the clouds seen in the sky.

3. Precipitation: Rain;

The clear plastic wrap covering the top of the glass jar, prevents the movement of the vapor further away, such that the tiny condensed vapor gather together, to form big droplets under the plastic wrap that falls back into the jar, which is similar to the process of rainfall

The above processes are repeated as more water evaporates from the jar condenses on the plastic wrap and falls back into the jar, showing the process by which water is recycled from the lake into the atmosphere and back to the lake.

Based on the provided data, we can create a demand schedule for the prices and the quantity demanded per month.

Let's first organize the data in a table:

Price ($) Quantity Demanded per Month

15 1

12 2

9 3

6 5

3 7

If you plotted these numbers on a graph, you would expect to see a downward-sloping curve, illustrating the inverse relationship between price and quantity demanded. As the price decreases, the quantity demanded per month increases.

Now let's consider Charlene's costs and profits from walking dogs. It costs her $2.00 for each bus ride to the dog owner's house.

To calculate her profit, we need to find her total revenue at each price point, then subtract her total costs.

Price ($) Quantity Demanded per Month Total Revenue ($) Total Costs ($) Profit ($)

15 1 15 2 13

12 2 24 4 20

9 3 27 6 21

6 5 30 10 20

3 7 21 14 7

From the table, we can see that Charlene will have the most profit ($21) when she walks 3 dogs per month, charging $9 per walk.

What is the inertia of motion? ​ ​

What is inertia of motion explain one example?​

Answers

THE INABILITY OF A BODY TO CHANGE ITS STATE OF MOTION BY ITSELF

example : a passenger tends to fall forward when breaks are applied in a bus

The tendency of an item to resist a change in its state of motion is referred to as inertia. It specifically refers to an object's resistance to any change in velocity, whether that change be in speed or direction.

What is Inertia ?

When you are riding in a car and the driver abruptly stops, you are experiencing inertia of motion. Because of inertia, your body wants to continue going forward at the same pace and in the same direction as before the brakes were applied. You will lean forward as a result, and if you are not wearing a seatbelt, you may be flung forward. Similarly, while the automobile speeds, your body tries to remain at rest owing to inertia, causing you to be motionless. Despite being widely accepted, Aristotle's theory of motion was challenged by prominent philosophers multiple times over the course of roughly two thousand years. For instance, Lucretius claimed that mobility rather than stasis (stagnation) was the "default state" of the matter (following, presumably, Epicurus).

(the turn of the screw)I scarce know how to put my story into words that shall be a credible picture of my state of mind; but I was in these days literally able to find a joy in the extraordinary flight of heroism the occasion demanded of me. I now saw that I had been asked for a service admirable and difficult; and there would be a greatness in letting it be seenoh, in the right quarter!that I could succeed where many another girl might have failed. It was an immense help to meI confess I rather applaud myself as I look back!that I saw my service so strongly and so simply. I was there to protect and defend the little creatures in the world the most bereaved and the most lovable, the appeal of whose helplessness had suddenly become only too explicit, a deep, constant ache of ones own committed heart. We were cut off, really, together; we were united in our danger. They had nothing but me, and Iwell, I had them. It was in short a magnificent chance. This chance presented itself to me in an image richly material. I was a screenI was to stand before them. The more I saw, the less they would. I began to watch them in a stifled suspense, a disguised excitement that might well, had it continued too long, have turned to something like madness. What saved me, as I now see, was that it turned to something else altogether. It didnt last as suspenseit was superseded by horrible proofs. Proofs, I say, yesfrom the moment I really took hold.This moment dated from an afternoon hour that I happened to spend in the grounds with the younger of my pupils alone. We had left Miles indoors, on the red cushion of a deep window seat; he had wished to finish a book, and I had been glad to encourage a purpose so laudable in a young man whose only defect was an occasional excess of the restless.

I was aware afresh, with her, as we went, of how, like her brother, she contrivedit was the charming thing in both childrento let me alone without appearing to drop me and to accompany me without appearing to surround. They were never importunate and yet never listless.
