What steps are involved in converting potential energy to kinetic energy, or kinetic energy to potential energy?

Physics
1 answer:
Ray Of Light [21]3 years ago
7 0

Explanation:

Potential energy is the energy obtained by an object due to the position of an object. Whereas kinetic energy is the energy obtained by an object due to its motion.

For example, an ball is placed over a building of height h. Then steps followed to covert its potential energy into kinetic energy are as follows.

Step 1: When ball is at placed over a building of height h, then it has only potential energy and no kinetic energy.

Step 2: A man pushes the ball and it moves in the downward direction.

Step 3: When ball starts to move or fall it gains kinetic energy, that is potential energy now becomes equal to 0.

Similarly, on reaching the ground and after bouncing a few times when it stop moving then kinetic energy converts into potential energy.

Twenty grams of a solid at 70°C is place in 100 grams of a fluid at 20°C. Thermal equilibrium is reached at 30°C.
zaharov [31]

Answer:

c. is more than that of the fluid.

Explanation:

This problem is based on the conservation of energy and the concept of thermal equilibrium

heat= m s \Delta T


m= mass

s= specific heat

\DeltaT=change in temperature

let s1= specific heat of solid and s2= specific heat of liquid

then

Heat lost by solid= 20(s_1)(70-30)=800s_1


Heat gained by fluid=100(s_2)(30-20)=1000s_2


Now heat gained = heat lost

therefore,

1000 S_2=800 S_1

S_1=1.25 S_2

so the specific heat of solid is more than that of the fluid.

Explain why xrays are used to take images of inside the body but UV isnt
Sidana [21]

Answer:

X-rays go all the way through the body, but ultraviolet rays do not.

Explanation:

An x-ray will show inside the body, but uv light isn't strong enough to go all the way through the body.

A small sphere with a mass of 441 g is moving upward along the vertical +y-axis when it encounters an electric field of 5.00 N/C
sweet-ann [11.9K]
In your question where the ask is to calculate the charge that the small sphere carries which is the mass of it is 441g moving at an acceleration of 13m/s^2 nad having and electric field of 5N/C. So the formula in getting the charge is mutliply the mass and the quotients of Acceleration and the Electric Field so the answer is 1,146.6
