Asimple pendulum of length 2.5 m makes 5.0 complete swings in 16 s. what is the acceleration of gravity at the location?

Explanation:

Length of pendulum = 2.5 m

Time taken for 5 swings = 16 seconds

Time taken for 1 swing = 3.2 seconds

Period of pendulum = 3.2 seconds.

We have equation for period of simple pendulum as

Where l is the length of pendulum and g is acceleration due to gravity.

Substituting

The acceleration of gravity at the location is 9.64 m/s²

it's a b and

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
