<h2>
The acceleration of gravity at the location is 9.64 m/s²</h2>
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
![T=2\pi \sqrt{\frac{l}{g}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bl%7D%7Bg%7D%7D)
Where l is the length of pendulum and g is acceleration due to gravity.
Substituting
![T=2\pi \sqrt{\frac{l}{g}}\\\\3.2=2\pi \sqrt{\frac{2.5}{g}}\\\\g=\frac{4\pi^2 \times 2.5}{3.2^2}\\\\g=9.64m/s^2](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bl%7D%7Bg%7D%7D%5C%5C%5C%5C3.2%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7B2.5%7D%7Bg%7D%7D%5C%5C%5C%5Cg%3D%5Cfrac%7B4%5Cpi%5E2%20%5Ctimes%202.5%7D%7B3.2%5E2%7D%5C%5C%5C%5Cg%3D9.64m%2Fs%5E2)
The acceleration of gravity at the location is 9.64 m/s²
Answer: False
explanation: because Total momentum is conserved only if the collision can be considered isolated from the influence of net external forces
Answer:
A. an increase in the height of the sound wave
Explanation:
Volume of the sound is measured by its intensity
So here we know that
intensity is directly depends on the square of the amplitude of the sound wave
so here as intensity depends on the loudness of the sound given as
![L = 10 Log(\frac{I}{I_o})](https://tex.z-dn.net/?f=L%20%3D%2010%20Log%28%5Cfrac%7BI%7D%7BI_o%7D%29)
so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase
So correct answer will be
A. an increase in the height of the sound wave
Not much changes, but there are some great pressure so some hills may form.
