Answer:
Height of the building = 35.78 m
Explanation:
Given that,
The time period of a pendulum is, T = 12 s
We need to find the height of the building. The formula for the time period of a pendulum is given by :
[tex]T=2\pi \sqrt{\dfrac{l}{g}}[/tex]
Where
l is the height of the building
[tex]l=\dfrac{T^2g}{4\pi^2}\\\\l=\dfrac{(12)^2\times 9.8}{4\times 3.14^2}\\\\l=35.78\ m[/tex]
So, the height of the building is 35.78 m.
