Explanation:both balls have momentum to start and they share it after collision
Explanation:
d) Magnetic force is the power that pulls materials together (magnet e. g iron)
an example :how magnet can pick up a coin.
e) frictional force produces when two surfaces are in contact with each other.
effects of friction : I) it produces heat
II) it causes loss in power.
Answer:
when two object at different temperatures are in contact with each other.
Explanation:
Answer:
Iron has a higher heat capacity than copper
Explanation:
The heat capacity of a substance is defined as the amount of heat required to raise the temperature of an object by 1°C.
The higher the heat capacity of a substance, the longer the time it takes for the substance to become hot when heated.
Since the copper rod becomes too hot to hold much sooner than the iron rod, it means that iron has a higher heat capacity than copper.
