If 400j of work is done on an object in 8 seconds, how much power does the object experience?

50w

45W

60W

408

50 W

Explanation:

Power can be found using the following formula.

p=w/t

where w is work and t is time.

400 Joules of work is done on the object in 8 seconds. Therefore,

w = 400 J

t = 8 s

Substitute these values into the formula.

p=400 J / 8 s

Divide 400 by 8

p=50 J/s

Add appropriate units. In this case, power uses Watts, or W. (1 Joule per second, or J/s is equal to 1 Watt, or W)

p = 50 W

The object experiences 50 Watts of power

50w

Explanation:

Power is equal to Energy divided by Time

∆E/t
