How many kilowatt hours does it take to lift an apple that weighs 100g 1 meter.(use 9.8 kg
1 answer:
Answer:
The answer to your question is Power = 0.98 W or 9.8 x 10⁻⁴ kW
Explanation:
Data
Power = ?
mass = 100 g = 0.1 kg
distance = 1 m
gravity = 9.8 m/s²
Formula
Power = Work / time
Process
1.- Calculate the Work
Work = Force x distance
Force = mass x gravity
Work = mass x gravity x distance
Work = (0.1 kg)(9,8)(1)
Work = 0.98 J
2.- Calculate the power
Power = 0.98 J / 1 h
Power = 0.98 W or 9.8 x 10⁻⁴ kW
