Answer 1

Half of it can be be at 1000 watt microwave oven!!!                                                                                                                                                                                                                                                                                                            I hope it help!!!!!!

Answer 2

Answer:

30000 J

Explanation:

Power is defined as the amount of work done per unit time:

$P=\frac{W}{t}$

where

P is the power

W is the work done

t is the time taken

In this problem, we know the power of the microwave oven: $P=1000 W$, and we are asked to find the work done in a time of $t=30 s$, so by re-arranging the equation we find:

$W=Pt=(1000 W)(30 s)=30,000 J=30 kJ$
