PHY 104 Oscillatory Motion Objective Question

Question

Worked Example 1: You measure your pulse to be 82 beats per minute. What is the period of your heartbeat in seconds?
Options
A 0.012 s
B 0.017 s
C 0.73 s
Correct Answer
D 1.37 s
Correct Answer

Option C is the correct answer.

Detailed Explanation

From Worked Example 1 on page 27: The frequency f = 82 beats/minute. To find the period T in seconds, first convert frequency to beats per second: f = 82 beats / (60 seconds) = 82/60 Hz. Then, T = 1/f = 60/82 s ≈ 0.73 s.

Hint

Period is the reciprocal of frequency. Convert beats per minute to beats per second first.
