Pulse rate of a noumal person is 75 per minute. The time period of heart is

A

`0.8 s `

B

`0.75` s

C

`1.25` s

D

`1.75` s

Text Solution

Verified by Experts

The correct Answer is:
A
The beat frequency of heart is
`v (75)/((1 "min")) = (75)/(60 s ) = 1.25 s^(-1)`
=1.25 Hz
The time period of heart is
`T = (1)/(v) = (1)/(1.25s^(-1))=0.8` s
