If the heart pushes 1 cc of blood in one second under pressure 20000 N/m 2 the power of heart is

A

0.02 W

B

400 W

C

`5xx10` W

D

0.2 W

Text Solution

Verified by Experts

The correct Answer is:
A
Power `= ("workdone")/("time") = ("pressure " xx "change in volume")/("time")`
`=(20000 xx 1 xx 10^(-6))/(1)= 2 xx 10^(-2)= 0.02W`
