power=work/time so if:
power=1000 j
work= x
time= 5 s then , 1000 J = x/5
(5) 1000 J= x/5 (5/1)
5000 J*s=x answer
100 watts
Yes, provided the rain takes place in the daytime. But the power output of the panels will be reduced.

The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.
1 How many windmills it takes to power a city depends on the amount and reliability of the wind, the power output of each windmill, and the power requirements of the city.
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
If it takes 3400J to lift a rock onto a ledge, what power is required to lift the rock onto the ledge in 4 seconds Power is energy per unit time. It is measured in watts (joules per second). As such if 3400 joules is transfeered in 4 seconds, the power equals 3400 / 4. The power required is therefore 850 watts.
Yes, provided the rain takes place in the daytime. But the power output of the panels will be reduced.
The answer depends on what form the output takes.
