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

Given:

Work = 300 Joule

time = 3 second

To find:

Power required to move a box = ?

Formula used:

P =

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 =

Where P = power required to move box

W = work done to move the box

t = time taken to move the box

P =

P = 100 Watt

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

Hence, Option (B) is correct.

iron would move it is magnetic there is a mag field around the current in the wire
