Question

On an average, a human heart is found to beat 75 times in a minute. Calculate its frequency and time period.

Answer 1

• 1 min=60s
• Heart beats per minute=75

Frequency=

• 75/60=5/4=1.25s^{-1}

Now

Time period:-

$\\ \rm{:}\dashrightarrow \dfrac{1}{\nu}$

$\\ \rm{:}\dashrightarrow \dfrac{1}{1.25}$

$\\ \rm{:}\dashrightarrow \dfrac{4}{5}$

$\\ \rm{:}\dashrightarrow 0.8s$
