Aloaded ski lift pulls 20 chairs with people sitting in them up 200 meters. each chair with a person has 250 kg of total mass. how much power does it take to lift them if the ride takes 10 minutes?

a. 16,333 w
b. 163,333 w
c. 980,000 w
d. 98,000,000 w

First, we calculate the energy needed to transport one chair:
Energy = mass * gravity * height
Energy = 250 * 9.81 * 200
Energy = 490,500 Joules

Total energy for 20 chairs:
20 * 490,500
= 9,810,000 Joules

Power is expressed in watts which is joules per second, so:
Power = 9,810,000 / (10 * 60)
Power = 16,350 Watts

The answer is A

A descriptive investigation cannot show a cause-and-effect relationship between bacteria growth and possible factors affecting growth.
