Answer:
Thermal energy produce =4,000 J.
Explanation:
Given that
Mechanical energy at the top of hill = 6,000 J
Mechanical energy at the bottom of hill = 2,000 J
We know that energy is conserve
Energy at top of hill = energy at bottom of hill + Thermal energy produce
So now by putting the values
Energy at top of hill = energy at bottom of hill + Thermal energy produce
6,000 = 2,000+ Thermal energy produce
Thermal energy produce =6,000-2,000 J
Thermal energy produce =4,000 J.
As we know that thermal energy produce due to friction when one mechanical component slides on the other mechanical component then always heat is generated and this heat is known as thermal energy.
