Answer:
In order to make a sound wave have a higher pitch you increase the frequency.
In order to increase the volume of a sound wave, you have to increase the amplitude.
Hope this helps!
Answer:
The work done on the wagon is 37 joules.
Explanation:
Given that,
The force applied by Charlie to the right, F = 37.2 N
The force applied by Sara to the left, F' = 22.4 N
We need to find the work done on the wagon after it has moved 2.50 meters to the right. The net force acting on the wagon is :
![F_n=F-F'](https://tex.z-dn.net/?f=F_n%3DF-F%27)
![F_n=37.2-22.4](https://tex.z-dn.net/?f=F_n%3D37.2-22.4)
![F_n=14.8\ N](https://tex.z-dn.net/?f=F_n%3D14.8%5C%20N)
Work done on the wagon is given by the product of net force and displacement. It is given by :
![W=F_n\times d](https://tex.z-dn.net/?f=W%3DF_n%5Ctimes%20d)
![W=14.8\ N\times 2.5\ m](https://tex.z-dn.net/?f=W%3D14.8%5C%20N%5Ctimes%202.5%5C%20m)
W = 37 Joules
So, the work done on the wagon is 37 joules. Hence, this is the required solution.

<h2><em>A. Rotation of Earth</em></h2>
<em>The moon rises in the east and sets in the west, each and every day. It has to. The rising and setting of all celestial objects is due to Earth's continuous daily spin beneath the sky</em><em>.</em>

Well I don't know. Let's actually LOOK at the picture and see if that helps.
A, B, C, and D all have the same TOTAL length, but A has the most waves crammed into that same total length.
By golly, that means the length of <u><em>each</em></u> wave in A must be shorter than each wave in B, C, or D.
The correct choice is <em> A </em>. Looking at the picture did the trick !
