________ is a measure of the internal energy that has been absorbed or transferred from one body to another, often due to a diff

stich3 [128]

Answer: Heat

Explanation: Heat is a form of energy, and it is exchanged between bodys when they are not at the same temperature.

Heat is transferred from the body with higher temperature to the one with lower tempertature, this is so that in time they end up being at the same temperature.

This means that the one with lower temperature is the one who absorbs the heat, and the one with higher temperature transfer it.

the kinetic energy of an object with mass m moving with a velocity of 5 m/s is 25 j what will be its kinetic energy when its vel

Dmitriy789 [7]

Answer:

100 J, 225 J

Explanation:

The kinetic energy of an object is given by:

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is the velocity of the object

In this problem, the initial kinetic energy of the object is

K = 25 J

Then, the velocity is doubled, which means

v' = 2v

Therefore, the new kinetic energy will be

$K'=\frac{1}{2}m(2v)^2 = 4(\frac{1}{2}mv^2)=4K$

Therefore, the kinetic energy has quadrupled:

$K' = 4(25)=100 J$

Later, the velocity is tripled, which means

v'' = 3v

Therefore, the new kinetic energy will be

$K''=\frac{1}{2}m(3v)^2 = 9(\frac{1}{2}mv^2)=9K$

Therefore, the kinetic energy has increased by a factor of 9:

$K' = 9(25)=225 J$
