The height of the dam , in a hydroelectric power station is 10 m . In order to generate 1 MW of electric power , the mass of water (in kg) that must fall per second on the blades of the turbines is

A

A)`10^(6)`

B

B)`10^(5)`

C

C)`10^(3)`

D

D)`10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Power , `P=(mgh)/(t)`
or `(m)/(t)=` mass of water fall second
`=(P)/(gh)=(1xx10^(6))/(10xx10)=10^(4)kg//s`

A rain drop of radius 2mm falls from a height of 500m above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original, height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey? What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10m s^(-1) ?
