Question

question 8 10 pts an elevator must have more power if the same number of people are transported upward at a slower speed. any time it moves faster regardless of the number of people on board. fewer people are transported upward at the same speed. more people are transported upward at the same speed.

Explanation:

Power in physics is defined as the rate of doing work (P = W/t). Work done in lifting people in an elevator is related to the force (which is related to the weight of people, F = mg) and the distance moved. When more people are transported upward at the same speed, more work is done in the same time - interval. Since power is work per unit time, more power is required.

Answer:

D. more people are transported upward at the same speed.
