Question

question 6 of 10
you eat a large meal and then hike up a hill. what kind of energy
transformation is your body performing?

a. chemical energy to kinetic energy and nuclear energy
b. gravitational potential energy to sound energy and nuclear energy
c. kinetic energy to chemical energy and light energy
d. chemical energy to kinetic energy and gravitational potential
energy

Explanation:

When you eat a meal, your body breaks down food (chemical energy). As you hike up a hill, your body moves (kinetic energy) and gains height (gravitational potential energy). There is no nuclear energy involved (eliminates A, B, C). Options B and C start with the wrong initial energy form. Option A has incorrect final energy forms (nuclear energy not relevant here). So the correct energy transformation is chemical energy (from food) to kinetic energy (moving) and gravitational potential energy (height gained while hiking up the hill).

Answer:

D. Chemical energy to kinetic energy and gravitational potential energy
