How long would a 700-w microwave have to run to use the same energy as a 100-w light bulb left on for 35 min?

The microwave will run for 5 minutes using the same energy as the bulb

Explanation:

Step one

Given data

Power for microwave =700-W

Power consumption for light bulb=100W

Time =35minto hours 35/60=0.58hrs

Energy consumption for bulb =power *time

= 100*0.58

=58.33joule

If the microwave wave is to consume this same amount of energy then it will run for

Energy =power *time

Time =energy /power

Time =58.33/700

Time =0.083hrs to min=0.083*60

Time =5 minutes

Taking it was dropped with inital velocity of 0m/s.

v = u+at

v = 0 + 9.8*1.5

v = 14.7s

(a=9.8m/s^2 << That's the acceleration due to gravity)
