Answer:
F = 1958.4 N
Explanation:
By volume conservation of the fluid on both sides we can say that volume of fluid displaced on the side of the car must be equal to the volume of fluid on the other side
so we have
![L_1A_1 = L_2A_2](https://tex.z-dn.net/?f=L_1A_1%20%3D%20L_2A_2)
![1.20(\pi 18^2) = L_2(\pi 5^2)](https://tex.z-dn.net/?f=1.20%28%5Cpi%2018%5E2%29%20%3D%20L_2%28%5Cpi%205%5E2%29)
![L_2 = 15.55 m](https://tex.z-dn.net/?f=L_2%20%3D%2015.55%20m)
so the car will lift upwards by distance 1.2 m and the other side will go down by distance 15.55 m
So here the net pressure on the smaller area is given as
![P = P_{atm} + \frac{12,000}{\pi (0.18)^2} + \rho g (1.2 + 15.55)](https://tex.z-dn.net/?f=P%20%3D%20P_%7Batm%7D%20%2B%20%5Cfrac%7B12%2C000%7D%7B%5Cpi%20%280.18%29%5E2%7D%20%2B%20%5Crho%20g%20%281.2%20%2B%2015.55%29%20)
excess pressure exerted on the smaller area is given as
![P_{ex} = \frac{12000}{\pi (0.18)^2} + 800(9.81)(16.75)](https://tex.z-dn.net/?f=P_%7Bex%7D%20%3D%20%5Cfrac%7B12000%7D%7B%5Cpi%20%280.18%29%5E2%7D%20%2B%20800%289.81%29%2816.75%29)
![P_{ex} = 2.49\times 10^5 Pascal](https://tex.z-dn.net/?f=P_%7Bex%7D%20%3D%202.49%5Ctimes%2010%5E5%20Pascal)
now the force required on the other side is given as
![F = P_ex (area)](https://tex.z-dn.net/?f=F%20%3D%20P_ex%20%28area%29)
![F = (2.49 \times 10^5)(\pi (0.05)^2)](https://tex.z-dn.net/?f=F%20%3D%20%282.49%20%5Ctimes%2010%5E5%29%28%5Cpi%20%280.05%29%5E2%29)
![F = 1958.4 N](https://tex.z-dn.net/?f=F%20%3D%201958.4%20N)
Answer:
size get smaller maybe there is no object remaining
:<span> </span><span>Under the assumption that a cell is made up of two concentric spheres you find the surface are of the inside sphere which will be your A.
You already have your separation and dielectric constant so just use the formula you stated towards the end of your question and you get 8.93x10^-11 Farads which is about 89pF</span>
The units for G must be ![[N][m^2][kg^{-2}]](https://tex.z-dn.net/?f=%5BN%5D%5Bm%5E2%5D%5Bkg%5E%7B-2%7D%5D)
Explanation:
The magnitude of the gravitational force between two objects is given by:
![F=G\frac{m_1 m_2}{r^2}](https://tex.z-dn.net/?f=F%3DG%5Cfrac%7Bm_1%20m_2%7D%7Br%5E2%7D)
where
F is the force
G is the gravitational constant
are the masses of the two objects
is the separation between the objects
We know that:
- The units of F are Newtons (N)
- The units of
are kilograms (kg) - The units of
are metres (m)
So, we can rewrite the equation in terms of G, to find its units:
![G=\frac{Fr^2}{m_1 m_2}=\frac{[N][m]^2}{[kg][kg]}=[N][m^2][kg^{-2}]](https://tex.z-dn.net/?f=G%3D%5Cfrac%7BFr%5E2%7D%7Bm_1%20m_2%7D%3D%5Cfrac%7B%5BN%5D%5Bm%5D%5E2%7D%7B%5Bkg%5D%5Bkg%5D%7D%3D%5BN%5D%5Bm%5E2%5D%5Bkg%5E%7B-2%7D%5D)

Answer:
Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Hope this helps you! :)
