A 500 grams ball is thrown vertically upwards with a speed of 20 metres per seconds. what is the kinetic energy of the ball at the height of 5 metres?
Answer:
Ek = 24.5 [J]
Explanation:
To solve this problem we must use the theorem of work and energy which tells us that potential energy is transformed into kinetic energy or vice versa.
In this way, the kinetic energy will be equal to the potential energy at each moment.
Ep = Ek
With the height and mass data, we can find the potential energy.
Ep =m*g*h
where:
Ep = potential energy [J] (energy in Joules)
m = mass = 500 [gr] = 0.5 [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 5 [m]
Ep = 0.5*9.81*5
Ep = 24.5 [J]
So the kinetic energy is the same that the potential energy.
Ek =24.5 [J]

A typical blood pressure is 120 mm Hg. How high would you need to hang an IV bag so that the fluid enters the blood stream at this pressure? Assume the IV fluid has a density of 1000 kg/m^3.
Answer:
1.63 m
Explanation:
The following data were obtained from the question given above:
Pressure (P) = 120 mmHg
Density (d) = 1000 Kg/m³
Height (h) =?
Next, we shall convert 120 mmHg to N/m². This can be obtained as follow:
760 mmHg = 101325 N/m²
Therefore,
120 mmHg = 120 mmHg × 101325 N/m² / 760 mmHg
120 mmHg = 15998.68 N/m²
Thus, 120 mmHg is equivalent to 15998.68 N/m².
Finally, we shall determine the height to which the IV bag should be placed so that the fluid can enter the blood stream. This is illustrated below:
Pressure (P) = 15998.68 N/m².
Density (d) = 1000 Kg/m³
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) =?
P = dgh
15998.68 = 1000 × 9.8 × h
15998.68 = 9800 × h
Divide both side by 9800
h = 15998.68 / 9800
h = 1.63 m
Therefore, the the IV bag should be placed at a height of 1.63 m

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1.0003, and the index of refraction of water is 1.33.
What is the angle of refraction rounded to the nearest whole number?
22°
24°
30°
42°
Answer: It’s A
Explanation:
22 degrees
The angle of refraction rounded to the nearest whole number is 22°.
What is refraction?It is the phenomenon of bending of light when it travels from one medium to another medium. The bending towards or away from the normal depends upon the medium of travel as well as the refractive index of the material.
By using Snell's law,
n₁sin(θ₁) = n₂sin(θ₂)
Where n is the refractive index and θ represents angles
Substituting the respective values given into the equation:
1.0003 * sin(30°) = 1.33 * sin(θ₂)
θ₂= 22°
The angle of refraction rounded to the nearest whole number would be 22°.

A scale reads 184 N when a piece of copper is hanging from it. What does it read (in N) when it is lowered so that the copper is submerged in water?
Answer:
163 N
Explanation:
The density of copper is about 8.96. The ratio of the weight in water to the weight in air is about 1-1/ρ, so is about 0.8884.
0.8884 × 184 N ≈ 163 N
The submerged weight is about 163 N.
A change of temperature of 20 C is equivalent to a change in thermodynamic temperature of
Answer:
20 K
Explanation:
It is given that,
The change in temperature is 20 C.
We need to find the change in thermodynamic temperature.
If teperauture T₁ = 0° C = 0+273 = 273 K
T₂ = 20° C = 20 + 273 = 293 K
The change in temperature,
[tex]\Delta T=T_2-T_1\\\\=293-273\\\\=20\ K[/tex]
So, the change in temperature of 20°C is equivalent to 20 K.
The change in thermodynamic temperature is equal to 20 Kelvin.
Given the following data:
Change in temperature = 20°CTo determine the change in thermodynamic temperature:
A thermodynamic temperature can be defined as an absolute measure of the average total internal energy possessed by a body or an object. Thus, thermodynamic temperature is typically measured in Kelvin (K).
Mathematically, the change in temperature of an object is given by the formula:
[tex]\theta = T_f - T_i[/tex]
Where:
[tex]T_i[/tex] is the initial temperature (0°C)[tex]T_f[/tex] is the final temperature (20°C).Next, we would convert the values in degree Celsius to Kelvin:
Conversion:
0°C = 273 K
20°C = 273 + 20 = 293 K
For the change in thermodynamic temperature:
[tex]\theta = 293 - 273\\\\\theta =20\;K[/tex]

Determine the rate at which the electric field changes between the round plates of a capacitor, 8.0 cm in diameter, if the plates are spaced 1.4 mm apart and the voltage across them is changing at a rate of 110 V/s .
Solution:
The relation between the potential difference and the electric field between the plates of the parallel plate capacitor is given by :
[tex]$E=\frac{V}{D}$[/tex]
Differentiating on both the sides with respect to time, we get
[tex]$\frac{dE}{dt}=\frac{1}{D}\frac{dV}{dt}$[/tex]
Therefore, the rate of the electric field changes between the plates of the parallel plate capacitor is given by :

When you turn off your bedroom lights, the kitchen lights can stay on. This is because your home is wired using which of the following? (AKS 10b / DOK 1)
A.
Fuses
B.
Series circuits
C.
Batteries
D.
Parallel circuits
When you turn off your bedroom lights, the kitchen lights can stay on. This is because your home is wired by using the series circuit. Hence, option B is correct.
What is a Series circuit?The amount of current in the flow circuits of each element in a series circuit is the same. This is due to the recent flow having a single path. The flow rate (marble speed) at any point in a circuit (tube) at any given moment in time has to be equal because electric current moves through a conductor like marble in a duct.
The requirement that all values (voltage, current, resistance, and power) relate to one another in terms of the identical two places in a circuit is a significant exception to Ohm's law.
Therefore, the wiring of the home is in series combination. So, option B is correct.

This question is incomplete, the complete question is;
Calculate the average induced voltage between the tips of the wings of a Boeing 747 flying at 970 km/hr above East Lansing. The downward component of the earth's magnetic field at this place is 0.7 × 10⁻⁴ T. (DATA: Assume that the wingspan is 60 meters.)
Answer:
the average induced voltage between the tips of the wings of a Boeing 747 flying is 1.132 Volts
Explanation:
Given that;
Speed S = 970 KM/hr
downward component of the earth's magnetic field B = 0.7 × 10⁻⁴
wingspan 1 = 60min
Velocity V = (970 × 10³) / 3600 = 269.44 m/s
So Average Induced Voltage E = VBI
we substitute
E = 269.44 × (0.7 × 10⁻⁴) × 60
E = 1.132 Volts
Therefore the average induced voltage between the tips of the wings of a Boeing 747 flying is 1.132 Volts

Is any force exerted on the vertical sides of the loop that you used in the experiment and how does it affect the apparent mass?
a. There is a force exerted on each side of the loop that are equal in magnitude and opposite in direction.
b. No force is exerted on the sides of the loop.The lengths of the sides of the loop are much smaller than the bottom section and therefore the force on the sides are negligible.
c. The force on the sides are not in the same direction in which the mass is measured and therefore it does not affect the results.
d. The force exerted on the sides of the loop cancel each other out.
The force on the sides is not in the same direction in which the mass is measured and therefore it does not affect the results. Option c is correct.
What is force?Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The force on the sides does not alter the results since it is not in the same direction as the mass being measured. The forces acting on the loop's sides cancel one another out.
The force on the sides is not in the same direction in which the mass is measured and therefore it does not affect the results.
Hence option c is correct.

Average acceleration of an object is the:
Change in its position divided by the change in time
Change in time divided by the change in its position
Change in its velocity divided by the change in time
Change in time divided by the change in its velocity
Answer:
Option (c) is correct.
Explanation:
Acceleration of an object is given by the formula as follows :
[tex]a=\dfrac{v-u}{t}[/tex]
Where
u and v are initial and final velocity
t is time
(v-u) is also called the change in velocity
So, the acceleration of an object is equal to the rate of change of velocity. Hence, the correct option is (c) " Change in its velocity divided by the change in time".

Answer:
Substitute the numbers for YOUR problem this is NOT the answer.
Explanation:
In a vacuum, a 74 gram feather will fall to the Earth at the same rate (acceleration) as a 7.26 kg bowling ball. Which one will hit the ground first? Then use Newton’s 2nd Law of Motion to explain which object (the feather or the bowling ball) experiences a greater force due to gravity.
Answer:
We know that both objects fall at with the same acceleration, let's define that acceleration as g = 9.8m/s^2
Then the acceleration of both objects will be:
A(t) = -9.8m/s^2
Where the minus sign is because the gravity pulls the objects down.
Now, to get the velocity of the objects, we integrate over time, and get:
V(t) = (-9.8m/s^2)*t + v0
Where V0 is the initial velocity of the objects, because we do not have information about this, we can assume that both objects have the same value of V0, so for now, the movement equations are the same for both of them
To get the position we integrate again over time and get:
P(t) = (1/2)*(-9.8m/s^2)*t^2 + v0*t + P0
Where P0 is the initial position and same as above, we can assume that is the same for both objects.
Then both objects have the same motion equations, and the mass does not appear in any of them, then we can conclude that they will hit the ground at exactly the same time, because their motion equations are exactly the same.
B) By Newton's second law we know that:
F = m*a
Force equals mass times acceleration.
We know that both objects suffer the same acceleration, 9.8m/s^2
Then the force for the feather will be:
(remember that 1kg = 1000g, then 74g = (74/1000) kg = 0.074kg)
F = 0.074kg*9.8m/s^2 = 0.7252 N
And for the bowling ball will be:
F = 7.26kg*9.8m/s^2 = 71.148 N
Then you can see that the bowling ball experiences a greater force.

An automobile traveling 88.0 km/h has tires of 72.0 cm diameter. (a) What is the angular speed of the tires about their axles
Answer:
angular speed = 67.91 rad/s
Explanation:
Given that,
The diameter of a tire, d = 72 cm
The radius of a tire, r = 36 cm = 0.36 m
Linear speed of an automobile, v = 88 km/h = 24.45 m/s
We need to find the angular speed of the tires about their axles. The relation between angular speed and angular speed is given by :
[tex]v=r\omega\\\\\omega=\dfrac{v}{r}\\\\\omega=\dfrac{24.45 }{0.36}\\\\\omega=67.91\ rad/s[/tex]
So, the angular speed of the tire is 67.91 rad/s.
What's the difference between speed and velocity
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
