Question

The heart of a man beats 75 times a minute. What is it's (a) frequency and (b) time period?

Answer 1

If a heart beats at 75 times a minute, then the frequency would be:

#f=75/60=5/4=1.25 Hz#

The period can be calculated as:

#T=1/f=4/5=0.8s#

Answer 2

Hi friend
--------------
Your answer
---------------------

Number of times the heart of a person beats in a minute = 75 times

(a) Frequency
-------------------------

1 minute = 60 seconds

Frequency = 75/60 Hertz => 1.25 Hertz

(b) Time period
-------------------------

Frequency = 1/ Time period [ V = 1/T formula]

1.25 = 1/T

T = 1/1.25 seconds => 0.8 seconds
