Answer:
80%
Explanation:
Efficiency = Power output / Power input × 100 %
To calculate efficiency we need to find power output of electric pump.
We can use,
Work done = Energy change
Work done per second = Energy change per second
Work done per second = Power
Therefore, Power = Energy change per second
= Change in potential energy of water per second
=mgh / t
= 200× 10×6 / 10
= 1200 W = 1.2 kW
Now use the first equation to find efficiency,
Efficiency = × 100%
= 80 %
Answer:
The smallest diameter is
Explanation:
From the question we are told that
The resolution of the telescope is
The wavelength is
From the question we are told that
So
Therefore
Now
So
=>
The smallest diameter is mathematically represented as
substituting values
