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

Explanation

To solve the problem of calculating the beat frequency and period of a human heart that beats 75 times in a minute, we can follow these steps:

### Step 1: Calculate the Frequency
The frequency (f) is defined as the number of cycles (or beats) per unit time. Here, we have 75 beats in one minute. To convert this to beats per second (which is the standard unit for frequency), we need to divide the number of beats by the number of seconds in a minute.

\[ f = \frac{\text{Number of beats}}{\text{Time in seconds}} = \frac{75 \text{ beats}}{60 \text{ seconds}} \]
