A simple pendulum takes 15 seconds to complete 5 oscillations. What is the time period of pendulum?

The distance between two stations is 300 km. A train takes 6 hours to cover this distance. Calculate the speed of the train.

• 25 km/h

• 50 km/h

• 50 m/s

• 50 km/s

A pendulum takes 0.5 seconds to make one oscillation about its mean position. How long will it take to make 5 oscillations?

One of the most common well-known periodic motion is that of

• Sundial

• Simple pendulum

• Digital clock

• Motion of a child on a see-saw

In a 100 meter race it is easy to decide whose speed is highest. How can we decide which is the highest?

• one who takes 100 sec to complete 100 metres

• one who takes 10 sec to complete 100 metres

• one who takes fatest time to cover the distance of 100 metres

• one who takes shortest time to cover 100 metres .
