Answer:
m = 1.6 x kg
Explanation:
It is given :
Height, h = 170 m
Number of light bulbs = 2.2 million
Power of one bulb = 35 W
Time = 6 minutes = 6 x 60 s
= 360 s
Now power required for 2.2 million bulbs = 2.2 million x 35 W
= 2200000 x 35
= 77000000 W
Now we know that Power = energy / time
Therefore, Energy = Power x time
= 77000000 x 360
= 27720000000
= 2.772 x J
For Dam, we know
Energy = m.g.h
where g = acceleration due to gravity
= 9.8 m/s2
m = mass of water required
h = height from which water falls
= 175 m
Therefore,
E = m.g.h
m = E / (g.h)
= 2.772 x / ( 9.8 x 175 )
= 2.772 x / 1715
= 1.6 x 10 kg
Therefore mass of water = 1.6 x kg
