Answer: Option B
Explanation:
When the thermal energy is transferred from a hotter body to the colder body then the transfer of energy takes place until the temperature of both the objects are same.
The energy from the hotter body is transferred to the colder body. Example: The heat transfer from the hotter water takes place into the colder water.
The energy transfer will stop only when the temperature of both the water will be same.
I'm like 98% it's D.
Momentum, a physics concept, is the product of mass and velocity of an object. An increase in either mass or velocity will increase an object's momentum. Momentum has the same direction as that of velocity.
Momentum in physics is the product of an object's mass (m) and velocity (v), represented as P=mv. Due to this relationship, if either the mass or the velocity of an object increases, its momentum will also increase. The momentum's direction is the same as the velocity's direction. If the direction of motion changes, the momentum's direction will also change.
Consider a situation where a car bumps into another car in front of it. Both the cars will experience a change in velocity and hence a change in momentum due to the collision. However, taking into account the principle of conservation of momentum, the total momentum before the collision would be equal to the total momentum after the collision, assuming that friction is negligible.
For example, a football player with greater mass running at high velocity will collide with greater impact because of greater momentum. Similarly, a smaller object moving with a high velocity can also achieve high momentum.

Answer:
Explanation:he ball bounces back up with nearly the same speed as it hit. i don,t know if is right
