The work required to move a box a particular distance is 300 J. How much power is required to move the box in 3 seconds?

A. 30 W
B. 100 W
C. 300 W
D. 900 W

Respuesta :

Given:

Work = 300 Joule

time = 3 second

To find:

Power required to move a box = ?

Formula used:

P = [tex] \frac{W}{t} [/tex]

Where P = power required to move box

W = work done to move the box

t = time taken to move the box

Solution:

Power required to move the box is given by,

P = [tex] \frac{W}{t} [/tex]

Where P = power required to move box

W = work done to move the box

t = time taken to move the box

P = [tex] \frac{300}{3} [/tex]

P = 100 Watt

Thus, Power required to move the box for 3 second is 100 Watt.

Hence, Option (B) is correct.
