Question

Convert 54km/hr into m/s and Calculate the Time-period of a simple Pendulumim if it takes 72 seconds to complete 24 oscillations.

Answer 1

Answer. 54km/hr=54×5/18=15m/s. hence 15m/s is greater than 6m/s.

Answer 2

Answer:

Explanation:

1 kilometer is equal to 1000 meters. 1 Hour is equal to 60 minutes. 1 minute is equal to 60 seconds. Hence, 54 km/h is equal to 15 m/s

2. The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds

3.given in photo

4.answer:3.6km

speed=4m/s

time=15min=15x60=900sec

distance=speed*time

=900x4

=3600m

=3.6km
