Answer: A) converting chemical energy to mechanical energy.
When a muscle contracts, it performs mechanical work. The chemical energy generated in the muscle cell gets converted to mechanical energy. The oxidation of carbohydrates and fats helps in contraction of muscles. The metabolic process generates ATP molecules which is a storehouse of energy. during contraction. These molecules break to generate energy.
When in the melting process particles start to move more freely when in the freezing process particles tend to slow and vibrate in place
well it depends on how much force was added but if they both have the same amount of force and they were rolled at the same time either they will bounce backwards or roll backwards not thats your question will they roll backwards are bounce backwards?
