repeat the experiment would be the easiest way to make sure u got the correct and accurate answer
Answer:
the catalyst is for activation energy
Answer: Sand
Explanation: Out of all the choices, sand is the only one that cannot react with other substances.
Answer:
Electrical energy to mechanical energy
Explanation:
In an electric motor, the energy transformation that is involve is a move from from electrical energy to mechanical energy.
For every system, according to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- An electric motor converts electrical energy to mechanical energy
- The electrical energy passes through and electromagnet set up.
- This then cause the motion to rotate.
- Therefore, electrical energy is transformed to mechanical energy.
it allows plants to survive and continue to reproduce
