question 5 (5 points) which of the following is an example of potential energy? a fan blade turning riding an exercise bike chewing food burning wood water stored in a reservoir question 6 (5 points) saved which of the following setups would convert centimeters to feet? cm × 2.54 cm / 1 in × 12 in / 1 ft cm × 1 in / 2.54 cm × 1 ft / 12 in cm × 2.54 in / 1 cm × 1 ft / 12 in cm × 2.54 cm / 1 in × 1 ft / 12 in cm × 1 in / 2.54 cm × 12 in / 1 ft

Explanation:

Question 5

Potential energy is stored energy. Water in a reservoir has gravitational - potential energy due to its position. The other options involve kinetic or chemical energy in action (turning fan blade, riding bike, chewing food, burning wood).

We know that 1 inch = 2.54 cm and 1 foot = 12 inches. To convert centimeters to feet, we first convert centimeters to inches by dividing by 2.54 (multiplying by $\frac{1\ in}{2.54\ cm}$) and then convert inches to feet by dividing by 12 (multiplying by $\frac{1\ ft}{12\ in}$).

Answer:

water stored in a reservoir
