Question

An electric pump of 1.6 KW is used to pump water for 32 minutes calculate the energy supplied by the pump in joule

Answer 1

Explanation:

Energy = power ^ time taken

Energy = 1.6kwh ^ 32/60 h

= 0.85J

Answer 2

HOPE IT HELPS :

GIVEN :

Power = 1.6 KW or 1600 W

Time = 32 min or 1920 seconds

HENCE ENERGY SUPPLIED BY PUMP IS :

E = Power x Time

E = 1600 x 1920

E =3072000 joules

E = 3.072 x 10^(6) joules
