Answer:
[tex]1.5\cdot 10^5 J[/tex]
Explanation:
The power used by an object is defined as:
[tex]P=\frac{W}{t}[/tex]
where
W is the amount of work done by the object
t is the time taken
In this problem, we have:
P = 500 W is the power of the microwave
[tex]t=5 min=300 s[/tex] is the time taken
So we can solve the formula for W, the work done by the microwave:
[tex]W=Pt=(500 W)(300 s)=1.5\cdot 10^5 J[/tex]
