a cyclist eats a full meal before going to ride a bike for 2 hours. which energy transformation happens during this process? chemical energy turns into mechanical energy. kinetic energy turns into potential energy. thermal energy turns into electromagnetic energy. potential energy turns into chemical energy.
Answer
Brief Explanations:
Food contains chemical energy. When the cyclist rides, this chemical - energy is used to do work (mechanical energy). Kinetic energy turning into potential energy is related to changes in motion and height, thermal to electromagnetic is not relevant here, and potential to chemical is not the correct transformation in this context.
Answer:
Chemical energy turns into mechanical energy.
