Question

A human heart on an average is found to beat 75 times a minute. Calculate its frequency

Answer 1

Time= 75/60 =1.25s
Frequency = 1/T= 1/1.25= 0.8s/beat

Answer 2

${\huge{\underline{\underline{\mathfrak{\green{♡ANSWER♡}}}}}}$.

✴.The beat frequency of heart =${75/(1min)}$

= ${75/(60s)}$

= ${1.25[tex]{s}}^-1$

=${1.25}$${Hz}$

=${1/(1.25[tex]{s^-1}}$

=${0.8s}$.
