Explanation:
The amount of the energy emitted by the microwave = 1100 J/s
It means that :
1100 J of the energy is emitted in 1 second
Also,
1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second
To calculate:
Time for emitting 4650 J of energy
Thus,
4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second
<u>Time = 4.2273 seconds</u>
I believe it is: The Law of Reflection says that the angle of incidence and the angle of reflection must be equal.
