Question

6. A simple pendulum takes 42
seconds to bomplete 60
oscillations the time period is -
0.7 s
4.2 s
3 s​

Answer 1

0.7

Explanation:

$time \: period \: = \frac{total \: time \: }{total \: oscillations}$

$\frac{42}{60 } = 0.7 \: seconds$

Answer 2

Answer:

time period of pendulum=time take to complete one osxillation

therefore

in 42 seconds=numberof oscillations=60

for one oscillationstime taken=44/60=0.7seconds
