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^(-10)`W

D

0.2 W

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Power `=("Workdone")/("Time")=("Pressure"xx"changein volume")/("Time")`
`=(20000xx1xx10^(-6))/(1)=2xx10^(-2)=0.02" W"`
