Answer:
A
Explanation:
Glucose is used which is the chemical energy, then his muscle moves which is the mechanical energy
When a skateboarder makes jump the energy transformed in chemical energy in from his food is transformed into mechanical energy. Thus,option A is correct.
What is the process of energy transfer?
The transfer of energy takes place in three ways radiation, conduction, and convention.
The term energy transfer shows the changes in energy that occur in and between organism within ecosystem.
When skateboarder jump it's energy transformed from potential energy to kinetic energy and thermal energy. The skateboarder has gravitational potential energy to going down the rap. Moving to ice skates have kinetic energy, which is known as energy of motion and then transformed to thermal energy due to friction.
The used glucose in the process is chemical energy and movement of muscle during skating is mechanical energy.
Therefore, when a skateboarder makes jump the energy transformed in chemical energy in from his food is transformed into mechanical energy. Thus, option A is
