This question is written wrong, I think u meant 20 kg?
Answer:
mechanical energy
Explanation:
Mechanical energy is the combination of both potential energy and kinetic
Mechanical energy can be divided as
1)kinetic energy, this energy vis regarded as the energy of motion
2) potential energy which is the stored energy of position.
Mechanical energy reffered to as
motion energy this energy is responsible for the movement of an object based on its position as well as motion.
Mechanical energy= U + K
Where U= potential energy
K= Kinectic energy
As the tire is sitting on top of a ramp, it posses "potential energy" as it is released and rolls down the ramp the potential is converted to Kinectic energy
Answer:
A) Cold object will start getting hot
B) Heat exchange will stop as the two object acquire the same temperature.
Explanation:
A) When one hot object and one cold object are kept in contact then the heat is transferred from the hot object to the cold object via different modes of heat transmission. Hence, the cold object starts getting hot
B) The transmission of heat from the hot object to the cold object will stop as the temperature of the two object becomes equal to each other.
