Aman enters a tall tower, needing to know its height. he notes that a long pendulum extends from the ceiling almost to the floor and that its period is 26.5 s. (a) how tall is the tower? m (b) if this pendulum is taken to the moon, where the free-fall acceleration is 1.67 m/s2, what is the period there?

Explanation:

It is given that,

Time period of the pendulum, T = 26.5 s

1. The time period of the pendulum is given by :

, l is the length of the pendulum

l = 174.32 meters

2. On the surface of moon, the acceleration due to gravity,

Time period is given by :

T = 64.19 seconds

Hence, this is the required solution.

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.
