question 9 of 10
after driving in stop-and-go traffic in his new hybrid, jesse notices that his car battery’s power level has increased. what could be a possible explanation?

a. when jesse used his cruise control, energy was saved in the battery.

b. during acceleration, the battery was shut off and fuel was used.

c. each time jesse hit his brakes, the saved energy was stored in the battery.

d. when jesse used his cruise control, the battery worked efficiently to power the car.

Explanation:

Hybrid cars use regenerative braking, where braking converts kinetic energy into electrical energy stored in the battery. In stop - and - go traffic, there's frequent braking. Option A: Cruise control is not typically used in stop - and - go traffic, so this is incorrect. Option B: In a hybrid, the battery and fuel work together during acceleration, and this doesn't explain battery power increase. Option D: Cruise control isn't used in stop - and - go traffic, and this option doesn't explain power increase. Option C correctly describes regenerative braking in hybrids, where braking saves energy (kinetic to electrical) and stores it in the battery.

Answer:

C. Each time Jesse hit his brakes, the saved energy was stored in the battery.
