Answer:
a 5 kilogram mass, at a height of 3 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.
Explanation:
Please find the figure attached below:
Answer:
a.Resistance of bulb=
=192 ohm
b.power consumed by bulb after motor disconnection=74.609 W
Explanation:
<u>a.Resistance of bulb=</u>
<u>=?</u>
As we know that 
putting R as resistance of bulb i.e. 

<u>b.power consumed by bulb after motor disconnection? </u>
from the figure we see that
are in series so

current through their resistance is

Power consumed by bulb is
