Answer:
Step-by-step explanation:
6A) Death Valley is located below sea level. It says it is -282 feet. This means that it is below 0 and sea level is marked at 0.
6B) 5280 + 282 = 5562 ft higher
6C) The closer you get to the ocean the closer you are to 0. If you were in the water floating on top you would be at 0.
13) all 3 are 28
The parenthesis have to stay. This is how we know to distrubute the 2 across the problem.
I got the same question and Im pretty sure its d. 20
the answer is 4.2 and i check if the answer is correct
and it was correct
<u>Answer-</u>
![\boxed{\boxed{L=\dfrac{g}{4\pi^2 f^2}}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7BL%3D%5Cdfrac%7Bg%7D%7B4%5Cpi%5E2%20f%5E2%7D%7D%7D)
<u>Solution-</u>
The equation for time period of a simple pendulum is given by,
![T=2\pi \sqrt{\dfrac{L}{g}}](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cdfrac%7BL%7D%7Bg%7D%7D)
Where,
T = Time period,
L = Length of the rod,
g = Acceleration due to gravity.
Frequency (f) of the pendulum is the reciprocal of its period, i.e
![f=\dfrac{1}{T}\ \Rightarrow T=\dfrac{1}{f}](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7B1%7D%7BT%7D%5C%20%5CRightarrow%20T%3D%5Cdfrac%7B1%7D%7Bf%7D)
Putting the values,
![\Rightarrow \dfrac{1}{f}=2\pi \sqrt{\dfrac{L}{g}}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B1%7D%7Bf%7D%3D2%5Cpi%20%5Csqrt%7B%5Cdfrac%7BL%7D%7Bg%7D%7D)
![\Rightarrow (\dfrac{1}{f})^2=(2\pi \sqrt{\dfrac{L}{g}})^2](https://tex.z-dn.net/?f=%5CRightarrow%20%28%5Cdfrac%7B1%7D%7Bf%7D%29%5E2%3D%282%5Cpi%20%5Csqrt%7B%5Cdfrac%7BL%7D%7Bg%7D%7D%29%5E2)
![\Rightarrow \dfrac{1}{f^2}=4\pi^2 \dfrac{L}{g}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B1%7D%7Bf%5E2%7D%3D4%5Cpi%5E2%20%5Cdfrac%7BL%7D%7Bg%7D)
![\Rightarrow L=\dfrac{g}{4\pi^2 f^2}](https://tex.z-dn.net/?f=%5CRightarrow%20L%3D%5Cdfrac%7Bg%7D%7B4%5Cpi%5E2%20f%5E2%7D)
Answer:
1/3
Step-by-step explanation:
there's 9 socks in total and 3 black socks so if it's simplyfied it would be 1/3
