1.	The power of a motor pump is 2 Kw .How much water per minute can the pump raise to a.height of 20 intrs. (given g= 10 m/s^2)
Answer» Given, power of pump = 2kW =2000W Time (t)= 60sec Height (h) = 20m g = 10m/s2 As you know, power =work done per unit time. Work done = mgh = m ×10×20 =200m Therefore, 2000W = 200m/60s Therefore, m = 600kg So, the pump can raise 600kg of water in one minute.

Answer»

Given, power of pump = 2kW =2000W

Time (t)= 60sec

Height (h) = 20m

g = 10m/s2

As you know, power =work done per unit time.

Work done = mgh = m ×10×20 =200m

Therefore, 2000W = 200m/60s

Therefore, m = 600kg

So, the pump can raise 600kg of water in one minute.
