B would be first cause they are tall then
c cause they are
short then D can they are tall then A
This is what I would say
Answer:
due to heaviness
Explanation:
because metal is heavier than water
Answer:
Part a)
![q_2 = -6.8 \mu C](https://tex.z-dn.net/?f=q_2%20%3D%20-6.8%20%5Cmu%20C)
Part b)
![F = 0.700 N](https://tex.z-dn.net/?f=F%20%3D%200.700%20N)
direction = downwards
Explanation:
As we know that the negative charge will experience the force due to some other charge below it
the force is given as
![F = 0.700 N](https://tex.z-dn.net/?f=F%20%3D%200.700%20N)
now we know that
![F = \frac{kq_1q_2}{r^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7Bkq_1q_2%7D%7Br%5E2%7D)
now plug in all data
![0.700 = \frac{(9 \times 10^9)(0.550\mu C)q_2}{0.220^2}](https://tex.z-dn.net/?f=0.700%20%3D%20%5Cfrac%7B%289%20%5Ctimes%2010%5E9%29%280.550%5Cmu%20C%29q_2%7D%7B0.220%5E2%7D)
![0.700 = 1.022\times 10^5 q_2](https://tex.z-dn.net/?f=0.700%20%3D%201.022%5Ctimes%2010%5E5%20q_2)
![q_2 = -6.8 \mu C](https://tex.z-dn.net/?f=q_2%20%3D%20-6.8%20%5Cmu%20C)
since this is a repulsion force so it must be a negative charge
Part b)
As per Newton's III law it will exert equal and opposite force on it
So here the force on the charge below it will be same in magnitude but opposite in direction
so here we have
![F = 0.700 N](https://tex.z-dn.net/?f=F%20%3D%200.700%20N)
direction = downwards
5320*14= 74480 gallons. <span>
First let us convert gallons to cm^3 and we get 2.819374858x10^8
cm^3.
We then multiply with density and then times 1000 to get it
in terms of tons.
Then multiply the number by 7 to get how many tons of crude
oil a single plane uses in 14 hrs.
Finally divide this by the production of crude oil.
