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

`1.25s`

D

`1.75s`

Text Solution

Verified by Experts

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