Question

A pendulum takes 40 min to complete 80 oscillations. Calculate the time period

Answer 1

⭐⭐⭐ Hey mate!!

__________________________________________________________

✓❄️frequency⚡ is number of oscillation per second.

So,

⚡If in 40 × 60 sec oscillates 80 times

❄️Then in 1 sec.. 80/40×60

= 1/30

Here,

⚡Frequency =1/30

⚡ time period = 1/frequency

♐⚡Time period will be = 30sec

Hope it will help you...✌️✌️
