The answer is A. conduction
Answer:
Thermal heat
Explanation:
The water heats up which it means it is thermal (heat/hot)
F = M*A
200N*10KG is 2000 newtons
so 2000 newton's is the normal force that is being exerted on the block
Answer:
Law of conservation of mechanical energy.
Explanation:
During motion of a block sliding on the floor from the bottom of the ramp to the moment it stops , kinetic energy is converted into potential energy so that total energy remains constant . No other conversion is taking place , if we consider friction to be absent in the system . Potential energy and kinetic energy form part of mechanical energy . So we can say that mechanical energy is conserved . Hence , system is following law of conservation of mechanical energy.
