Answer: The work done by the toaster is 270,000 J
Explanation:
Power is defined as the ratio of rate of work done by an object with respect to time.
Mathematically,
\(P=\frac{W}{t}\)
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:
\(1500W=\frac{W}{180s}\\\\W=(1500W\times 180s)=270,000J\)
Hence, the work done by the toaster is 270,000 J
