Question

A doctor counts 68 heartbeats in 1.0 minute. What are the corresponding period and frequency of the heart rhythm

Answer 1

`f=1.13s^(-1)=1.13Hz`

Step-by-step explanation:

Hello,

In this case, a frequency stands for a rate in which some action is done per unit of time. In this case, for the heartbeat, since 68 actions (heartbeats) occur in 1.0, the frequency turns out:

`f=(68)/(1.0min)=68min^(-1)`

Or as most commonly used in Hz (
`s^(-1)`):

`f=68(1)/(min) *(1min)/(60s)=1.13s^(-1)=1.13Hz`

Best regards.
