Answer:

90000J

Explanation:

Given parameter:

Power of the microwave = 1000watt

time for soup to heat = 90s

Unknown:

Amount of energy delivered = ?

Solution:

Electric power is the rate at which electrical energy is transferred.

  Electrical power = [tex]\frac{electrical energy}{time}[/tex]

 Electrical energy = electrical power x time

input the variables;

 Electrical energy = 1000 x 90 = 90000J
