An electric motor is used to hoist building supplies from the ground to the roof of a building. how much work can the motor do in 12 seconds if its power output is 1.5 kw (1,500 w)?

18000 J is the work can do by the motor.

Explanation:

If an electric motor works for 12 seconds and the power output is 1.5 KW = 1500 Watts we need to find how much work can an electric motor does.  

We know that,

“Power” is defined as the “rate” of doing “work”, the “energy” transferred or converted per unit time. Mathematically,  

Where, units of power is “Watt”, units of work is “Joule” and time in “seconds”.

Substitute the given values to find work

1500 × 12 = work

Work = 18000 Joules

Therefore, work can done by an electric motor is 18000 J.

18,000 J

Explanation:

1500 x 12 = 18,000 J

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."
