I think its mass. :) if correct please brainly!
Kinetic energy because, the object is in motion.
<u>Answer </u>
A. that the initial gravitational potential energy of the masses transformed into kinetic energy of the paddles and then to thermal energy in the water
<u>Explanation</u>
James Joule allowed some water to fall from a height of 1 foot. the water would turn a paddle wheel at the bottom causing a temperature of water to raise.
The height form which the water fell, mass and the temperature of water was measured and used to calculate mechanical equivalent of heat.
From the choices given the best answer is A. that the initial gravitational potential energy of the masses transformed into kinetic energy of the paddles and then to thermal energy in the water.
The answer is that it is an elastic collision.
<u>Explanation:</u>
When two objects come in direct contact with each other, the collision occurs. It is the event in which two or more bodies exert forces on each other in about a relatively short time.
As a result of a collision, No losses in the kinetic energy.
The formula for an elastic collision of momentum is given by
m1u1 +m2u2 = m1v1 + m2v2
where m1,m2 represents the mass of 1st and 2nd body
u1, u2 represents the initial velocity of the first and second body
v1, v2 represents the final velocity of the first and second bodies.
During a collision, the kinetic energy before the collision will be equal to the kinetic energy after the collision.
Smaller the force, greater the collision acting upon the object.
