Question

as bronco brown steps off a hovering high - flying helicopter and falls in the air, he experiences an impulse. a decreasing acceleration. an increasing speed. all of the above question 14 1 pts strictly speaking, more fuel is consumed by your car if the air conditioner, headlights, or even a radio is turned on. this statement is true. true only if the cars engine is running. false.

Explanation:

1. For the first question: When a person steps off a hovering helicopter, an impulse acts on them due to the change in momentum. As they fall, air - resistance increases, so the net force (and thus acceleration) decreases over time. Also, their speed initially increases as they fall.
2. For the second question: When the air - conditioner, headlights, or radio are turned on in a car, the alternator has to work harder to generate more electricity. This requires more mechanical energy from the engine, which in turn consumes more fuel when the engine is running.

Answer:

1. D. all of the above
2. B. true only if the car's engine is running.
