| January 31, 2021 | education
These tasks: A (operation of the pump used when pumping out water) = 16 J; t (pump running time) = 20 s.
The power of the electric pump used can be determined by the formula: N = A / t.
Let’s calculate: N = 16/20 = 0.8 W.
Answer: The electric pump used has a power of 0.8 W.
