Question

If a body consists of 64C charge then calculate number of electrons

Answer 1

Answer:

Water is falling on the Blades of a turbine at the rate of 6 * 103 kg per minure . The height of the fall is 10 m . Claculate the power given to the turbine.turbine at a rate of 100 kg/s from a certain spring.If the height of the spring be 100 metres, the power transferred to the turbine will be:

A .

100 kW

B .

10 kW

C .

1 kW

D .

1000 kW

m=100 kg

Height=100 m

w=mgh

⇒w=100×10×100=105 J

Power=TimetakenWorkdone 

⇒Power=1105

⇒Power=105 W

⇒Power=102×103 W=102 kW
