Answer:
A longitudinal wave is a wave where the movement of the medium is in the same direction as the wave. On the other hand, a transverse wave is a wave where the movement of the medium is at a right angle to the wave direction.
Explanation:i got this right on a quiz so i know its right
A theromometer is the increase or decrease of earths atmospheric temperture, thats how you would measure the temperture of the air around you.
We have the equation for electric field E = kQ/![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
Where k is a constant, Q is the charge of source and d is the distance from center.
In this case E is inversely proportional to ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
So, ![\frac{E_{1} }{E_{2}} = \frac{d_{2}^{2}}{d_{1}^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BE_%7B1%7D%20%7D%7BE_%7B2%7D%7D%20%3D%20%5Cfrac%7Bd_%7B2%7D%5E%7B2%7D%7D%7Bd_%7B1%7D%5E%7B2%7D%7D)
= 485 N/C
= 0.208 cm
= 0.620 cm
= ?
![\frac{485 }{E_{2}} = \frac{0.620^{2}}{0.208^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B485%20%7D%7BE_%7B2%7D%7D%20%3D%20%5Cfrac%7B0.620%5E%7B2%7D%7D%7B0.208%5E%7B2%7D%7D)
= ![\frac{485*0.208^{2}}{0.628^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B485%2A0.208%5E%7B2%7D%7D%7B0.628%5E%7B2%7D%7D)
= 53.20 N/C
Answer: 3 square feet
Explanation: I took the test
It means that they were set earlier therefor they are older.
