Question

The sound produced by a seconds pendulum will be audible to us.

• A. True
• B. False

Answer 1

The correct option is B False

A seconds pendulum has a time period of 2 seconds, i.e., T = 2 s. Hence, its frequency is given by:
$f=\frac{1}{T}=\frac{1}{2}=0.5Hz$
The audible frequency range for our hearing is 20-20000 Hz. As the calculated frequency is less than 20 Hz, the sound will not be audible to us.
