The beat frequency of heart of a person is 1.35 H z. How many times, does it beat in a minute ? What is the time period ?
Hint `:` Number of oscillations in `1s =1.35`
Find number of oscillations in 60 s , and `T= (1)/(v)`

Explanation

To solve the problem, we need to find out how many times the heart beats in a minute and what the time period of each beat is.

### Step-by-Step Solution:

1. **Understanding Frequency**:
The beat frequency of the heart is given as 1.35 Hz. This means that the heart beats 1.35 times per second.

2. **Calculating Beats in One Minute**:
