Question

12. A water pump can lift 90 kg
of water per minute to a tank.
If the potential energy of the
water stored is 21.6 kJ,
compute the height of the
water tank. Take g = 10 m/s2. *​

Answer 1

Answer:

whats kJ??

Explanation:

Answer 2

An

Explanation:

MASS= 30KG

POTENTIAL ENERGY = 23.4 KJ = 23.4 ×10^3 KJ

WE KNOW THAT POTENTIAL ENERGY IS GIVEN BY :-

POTENTIAL ENERGY = mgh

H= POTENTIAL ENERGY ÷ mg

H= 23.4×10^3 ÷ 30×10

H= 78m

HENCE HEIGHT IS 78m.
