ICSE − Q & A

An engine can pump 30000 litres of water to a vertical height of 45m in 10 minutes. Calculate the power of the machine if it's efficiency is 80%.[g=10m/s2 , density of water=1000kg/m3]
What answer doyou get?

Name the subjective and objective properties of sound.

Plz give similarity bw ac generator and dc motor 2 points

safety limit of sound level in human ear?

is V = v + Emf or V = emf - v
V = Terminal voltage
v= voltage drop
