A nurse in a hospital , noted for a patient that heart was beating 75 times a minutes. Find its frequency and time period.

Text Solution

Verified by Experts

Number of oscillations(beats) in 60s =75
Number of oscillations (beats) n 1 s=`(75)/(60)=1.25`
`therefore` Beat frequency of heart =1.25`s^(-1)`=1.25 Hz
Time period , T=`(1)/(n)=(1)/(1.25)=0.8s `
