A car engine supplies 2.0 x 103 joules of energy during the 10. seconds it takes to accelerate the car along a horizontal surfac
e. What is the average power
developed by the car engine while it is accelerating?
1. 2.0 x 10^1 w
2. 2.0 x 10^2 w
3. 2.0 x 10^3 W
4. 2.0 x 10^4 w
1 answer:
Answer: 2. 2.0*10^2 W
Explanation:
Power = Work/Time
Power = (2.0*10^3) Joules/10 seconds
Power = 2.0*10^2 Watts
