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 occurrences of a repeating event per unit of time. In this case, the heart beats 75 times in one minute. To find the frequency in hertz (Hz), which is beats per second, we need to convert minutes to seconds.

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