Answer: The work done by the toaster is 270,000 J

Step-by-step explanation:

Power is defined as the ratio of rate of work done by an object with respect to time.

Mathematically,


P=(W)/(t)

where,

P = power of the toaster = 1500 W

W = work done by the toaster = ?

t = time taken = 3 mins = 180 sec (Conversion factor: 1 min = 60 sec)

Putting values in above equation, we get:


1500W=(W)/(180s)\\\\W=(1500W* 180s)=270,000J

Hence, the work done by the toaster is 270,000 J
