1) The heat added to system
2) 800J
3) I'm not sure but I think it would be 300J.. Not certain tho
Answer:
Given that,
- Power = 2000 W
- time = 60 seconds
- distance= 10m
Power = work done ÷ time
Here, since the movement is vertical, w = mgh
So,
Power = mgh÷t
2000 = (m × 9.8 ×10) ÷ 60
m = (2000 ×60) ÷98
m = 1224.5kg
Answer:
heat came from the supernova that led to the formation of solar system
