An iron Cub has each 15cm long at 20c. What will be :
1 the new surface of a face weather temperature rise to 80c
2 the volume of the same final temperature

The current in the coil is approximately 0.1419 A (amps).

To find the current in a coil, we need to use the formula for magnetic field strength (B) in a solenoid:
B = μ₀ × n × I
Where:
- B is the magnetic field strength (given as 388 x 10⁻³ T)
- μ₀ is the permeability of free space (approximately 4π x 10⁻⁷ T m/A)
- n is the number of turns per meter (density of turns, given as 861658 turns/m)
- I is the current in the coil (the value we want to find)
First, let's plug in the given values:
388 x 10⁻³ T = (4π x 10⁻⁷ T m/A) × 861658 turns/m × I
Now, we need to isolate I by dividing both sides of the equation by (4π x 10⁻⁷ T m/A × 861658 turns/m):
I = (388 x 10⁻³ T) / (4π x 10⁻⁷ T m/A × 861658 turns/m)
Next, we can calculate the current:
I ≈ 0.1419 A

The formula for the horizontal range is dependent on the initial velocity, angle of projection, and acceleration due to gravity. Therefore, the formula is [tex]range = velocity\;horizontal \times 2V0y / g \times sin\theta[/tex]

The range of a projectile refers to the horizontal distance it covers during its flight. To derive a formula for the horizontal range of a projectile, we can use the kinematic equations.

The horizontal motion of a projectile is constant, and we can use the equation:

distance = velocity × time

In the horizontal direction, the initial velocity of the projectile remains constant throughout its flight. Thus, the horizontal distance traveled can be calculated as:

range = velocity horizontal × time

To determine the time, we can use the vertical motion equation:

[tex]y = V0y \times t + 1/2 gt^2[/tex]

Where y is the vertical displacement, V0y is the initial vertical velocity, g is the acceleration due to gravity, and t is the time.

We know that at the maximum height, the vertical velocity is zero. Thus, the time taken to reach maximum height is:

t = V0y / g

The time taken for the projectile to reach the ground from the maximum height is also equal to t.

Substituting this value of t into the horizontal distance equation gives:

[tex]range = velocity\;horizontal \times 2V0y / g \times sin\theta[/tex]

where θ is the angle of projection.

The speed of the ball bearing before the collision was: 1.75 m/s.

We can use the principle of conservation of angular momentum to solve this problem. Initially, the angular momentum of the system (clay cylinder + potter's wheel) is:

L1 = I1 * ω1

where I1 is the moment of inertia of the clay cylinder, and ω1 is its angular velocity.

When the ball bearing is thrown and sticks to the clay, the system's angular momentum changes due to the external torque exerted by the ball bearing. The change in angular momentum is:

ΔL = r * p * sin(θ)

where r is the radius of the cylinder, p is the linear momentum of the ball bearing before the collision, and θ is the angle between the normal to the clay surface and the direction of p. Since the ball bearing is thrown horizontally, θ = 60°.

Since the ball bearing sticks to the clay, the final system consists of a larger cylinder with a mass of 23.182 kg (23.0 kg clay cylinder + 0.182 kg ball bearing) and a new moment of inertia I2. The final angular velocity is ω2.

The conservation of angular momentum principle can be expressed as:

L1 + ΔL = I2 * ω2

Solving for the initial linear momentum p, we get:

p = (I2 * (ω2 - ω1)) / (r * sin(θ))

To find I2, we can use the formula for the moment of inertia of a solid cylinder:

I2 = (1/2) * M * R^2

where M is the mass of the larger cylinder and R is its radius. Since the clay cylinder and ball bearing stick together, their combined radius is still 19.0 cm.

Substituting the given values, we get:

I2 = (1/2) * (23.182 kg) * (0.19 m)^2 = 0.328 kg*m^2

To find ω2, we can use the fact that the final angular velocity is half the initial angular velocity:

ω2 = (1/2) * ω1 = (1/2) * (2π/1.70 s) = 2.33 rad/s

Finally, substituting all the values, we get:

p = (0.328 kgm^2 * (2.33 rad/s - 2π/1.70 s)) / (0.19 m * sin(60°)) = 0.319 kgm/s

The speed of the ball bearing before the collision is equal to its linear momentum divided by its mass:

v = p / 0.182 kg = 1.75 m/s

Therefore, the speed of the ball bearing before the collision was 1.75 m/s.

The rate at which the distance from the plane to the station is increasing is 255(sqrt(3)) mi/h when the plane is 2 mi away from the station.

To solve this problem, we will use the Pythagorean theorem and related rates.

Let x be the horizontal distance from the radar station to the plane, y be the altitude of the plane, and z be the distance between the plane and the radar station. We are given that y = 1 mi and the speed of the plane is 510 mi/h. We want to find the rate at which z is increasing when z = 2 mi.

The Pythagorean theorem states that x^2 + y^2 = z^2. Differentiating both sides with respect to time t, we get:

2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt)

Since the plane is flying horizontally and maintains a constant altitude, dy/dt = 0. We're given that dx/dt = 510 mi/h. Now, we need to find x when z = 2 mi. Using the Pythagorean theorem, we have:

x^2 + 1^2 = 2^2
x^2 = 3
x = sqrt(3)

Now, we can plug in the values for x, dx/dt, y, and z into the differentiated equation:

2(sqrt(3))(510) + 2(1)(0) = 2(2)(dz/dt)

Solving for dz/dt:

1020(sqrt(3)) = 4(dz/dt)
dz/dt = 255(sqrt(3)) mi/h

When calculating the stopping distance, various factors come into play, including reaction time, road conditions, vehicle weight, and braking efficiency. However, a commonly used estimate for the stopping distance at 55 mph (miles per hour) is approximately 4 to 5 times the thinking distance, which is the distance traveled during the driver's reaction time.

Assuming an average reaction time of 1.5 seconds, the thinking distance can be estimated by considering the speed:

Thinking Distance = Speed × Reaction Time

Converting 55 mph to feet per second (fps):

55 mph = 55 × 1.46667 fps (1 mph ≈ 1.46667 fps)

Now, calculating the thinking distance:

Thinking Distance = 55 × 1.46667 × 1.5 = 120.9335 feet (approximately)

Adding this thinking distance to the braking distance, we can estimate the overall stopping distance.

Therefore, the approximate stopping distance at 55 mph would be:

Stopping Distance ≈ Thinking Distance + Braking Distance

Stopping Distance ≈ 120.9335 feet + Braking Distance

When fertilizers enter surface water, they can cause several problems in the watershed:

1. Eutrophication:  Fertilizers contain nutrients such as nitrogen and phosphorus, which are essential for plant growth. However, when these nutrients enter surface water bodies through runoff or leaching, they can lead to excessive nutrient enrichment, a process called eutrophication. This excessive nutrient load stimulates the growth of algae and aquatic plants, resulting in algal blooms and dense vegetation. These blooms can deplete oxygen levels in the water, leading to hypoxia or even anoxia, which can harm or kill fish and other aquatic organisms.

2. Harmful Algal Blooms (HABs):  Excessive nutrients from fertilizers can promote the growth of harmful algal species, known as harmful algal blooms (HABs). These algae produce toxins that can be detrimental to the health of aquatic organisms, including fish, shellfish, and other wildlife. In addition, some of these toxins can contaminate the water, making it unsafe for human use and posing risks to public health.

3. Disruption of Aquatic Ecosystems: Fertilizer runoff can alter the natural balance and composition of aquatic ecosystems. Excessive plant growth due to nutrient enrichment can outcompete native species, leading to a decline in biodiversity. Changes in species composition can disrupt ecological interactions, such as predator-prey relationships and competition, which can have cascading effects on the entire ecosystem.

4. Degraded Water Quality: Fertilizers can contribute to water pollution by introducing excess nutrients into surface water. Besides promoting algal growth, these nutrients can also affect water quality by causing increased turbidity, reduced clarity, and altered pH levels. Such changes can negatively impact aquatic organisms and their habitats, as well as limit recreational activities and drinking water resources.

5. Nutrient Transport to Coastal Areas: Fertilizer runoff from watersheds can be transported to coastal areas through rivers and streams. The excess nutrients can contribute to the development of coastal dead zones, where oxygen levels are severely depleted, resulting in the loss of marine life and disrupting fisheries and recreational activities.

To mitigate these problems, it is crucial to adopt sustainable farming practices, such as precision agriculture, where fertilizers are applied in a targeted and controlled manner. Implementing buffer zones, constructed wetlands, and other best management practices can help filter and reduce nutrient runoff into surface water.

The piano wire must be stretched to a tension of 11.4 N to ensure that it vibrates at the D4 note.

Linear is a type of mathematical equation or function which has a variable that is raised to the power of one. It is also known as a straight line equation as it follows a straight line when plotted on a graph. Linear equations are used in a variety of fields such as science, engineering, business and economics. Linear equations are useful for finding solutions to problems that have a linear relationship between the variables.

The tension on the wire can be determined using the formula
T = (2π2f²L²)/(386.4),
where T is the tension, f is the frequency, and L is the length of the wire. In this case, the tension would be [tex]T = (2\pi2(293.7)2(0.44)2)/(386.4) = 11.4 N[/tex].
Therefore, the piano wire must be stretched to a tension of 11.4 N to ensure that it vibrates at the D4 note.

The distance among the two slits is 1.73 x 10⁻³ cm.

The third black fringe will appear 0.627 cm from the center of the dazzling fringe.

(a) The distance between the central bright fringe and the third bright fringe is given by:

Δy = (nλD) / d

where Δy is the distance between the central fringe and the nth bright fringe, λ is the wavelength of the light, D is the distance between the slits and the screen, and d is the distance between the slits.

Substituting the given values, we get:

3.11 cm = (1 x 632.8 nm x 85.0 cm) / d

Solving for d, we get:

d = (1 x 632.8 nm x 85.0 cm) / 3.11 cm = 1.73 x 10⁻³ cm

Therefore, the distance between the two slits is 1.73 x 10⁻³ cm.

(b) The distance between the central bright fringe and the nth dark fringe is given by:

Δy = [(2n - 1)λD] / (2d)

where Δy is the distance between the central fringe and the nth dark fringe, λ is the wavelength of the light, D is the distance between the slits and the screen, and d is the distance between the slits.

Substituting the given values and n=3, we get:

Δy = [(2 x 3 - 1) x 632.8 nm x 85.0 cm] / (2 x 1.73 x 10⁻³ cm) = 0.627 cm

Therefore, the third dark fringe will occur 0.627 cm away from the central bright fringe.

A. the distance between the two slits is approximately 12.8 micrometers. B. the third dark fringe will occur at a distance of approximately 0.557 cm from the central bright fringe.

Slit is a term used to refer to a long, narrow opening or gap. It is most commonly used to describe a thin cut in a piece of material or a surface. Slits are used in a variety of fields, including engineering, manufacturing, and architecture.

A. The distance between the two slits can be calculated using the equation:
d sinθ = mλ
First, we need to calculate the wavelength of the light using the frequency:
[tex]\lambda = c/f = (3.00 \times 10^8 m/s) / (6.32 \times 10^{14} Hz) = 4.74 \times 10^{-7} m[/tex]
[tex]tan \theta = (3.11 cm) / (85.0 cm)[/tex]
[tex]\theta = tan^{-1} (3.11 cm / 85.0 cm) = 2.10^{\circ}[/tex]
Finally, we can substitute the values into the equation and solve for d:
[tex]d = m\lambda / sin\theta = (3)(4.74 \times 10^{-7} m) / sin(2.10^{\circ}) \approx 1.28 \times 10^-5 m = 12.8 \mu m[/tex]
Therefore, the distance between the two slits is approximately 12.8 micrometers.

B. The distance from the central bright fringe to the third dark fringe can be calculated using the equation:
[tex]y = (m + 1/2) (\lambda d)\\y = (m + 1/2) (\lambda D/d) = (3 + 1/2) (4.74 \times 10^{-7} m) (85.0 cm) / (12.8 \times 10^{-6} m) \approx 0.557 cm[/tex]
Therefore, the third dark fringe will occur at a distance of approximately 0.557 cm from the central bright fringe.
