Question

7. The heart of a man beats 75 times a minute. What is its frequency?

​

Answer 1

Answer:

1.25 Hz

Explanation:

1.25 Hz

75 beats/60 seconds = 1.25 beats per second which can be expressed as 1.25 Hz. The time period of the heart beat is an expression of seconds per beat (the duration of each heartbeat). 60 seconds/75 beats = 0.8 seconds per beat.

Answer 2

$frequency = \frac{1}{time} = \frac{1}{75}$
