Weight of an object is given by the formula W = m x g , where
m : mass of the object
g : gravitational acceleration
It is <u>independent of the horizontal </u><u>acceleration</u>.
<h3>What do we mean by weight of an object?</h3>
Weight is a gauge of how strongly gravity is<u> pulling something down.</u> It is dependent on the object's mass, or how much matter it consists of. It also depends on the <u>object's uniformly distributed</u> downward acceleration caused by gravity.
This equation can be used to express weight:
W = m x g
<h3>What is the difference between weight and mass of an object?</h3>
In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably; nevertheless, the two concepts don't have the same meaning. In contrast to weight, which is a <u>measurement of</u> how the <u>force</u> of gravity works upon a mass, mass is the <u>amount of substance</u> in a material.

Answer:
at the beginning: ![2.3\cdot 10^{-10} F](https://tex.z-dn.net/?f=2.3%5Ccdot%2010%5E%7B-10%7D%20F)
when the plates are pulled apart: ![1.1\cdot 10^{-10} F](https://tex.z-dn.net/?f=1.1%5Ccdot%2010%5E%7B-10%7D%20F)
Explanation:
The capacitance of a parallel-plate capacitor is given by
![C=k \epsilon_0 \frac{A}{d}](https://tex.z-dn.net/?f=C%3Dk%20%5Cepsilon_0%20%5Cfrac%7BA%7D%7Bd%7D)
where
k is the relative permittivity of the medium (for air, k=1, so we can omit it)
is the permittivity of free space
A is the area of the plates of the capacitor
d is the separation between the plates
In this problem, we have:
is the area of the plates
is the separation between the plates at the beginning
Substituting into the formula, we find
![C=(1)(8.85\cdot 10^{-12}F/m)\frac{0.210 m^2}{8.15\cdot 10^{-3} m}=2.3\cdot 10^{-10} F](https://tex.z-dn.net/?f=C%3D%281%29%288.85%5Ccdot%2010%5E%7B-12%7DF%2Fm%29%5Cfrac%7B0.210%20m%5E2%7D%7B8.15%5Ccdot%2010%5E%7B-3%7D%20m%7D%3D2.3%5Ccdot%2010%5E%7B-10%7D%20F)
Later, the plates are pulled apart to
, so the capacitance becomes
![C=(1)(8.85\cdot 10^{-12}F/m)\frac{0.210 m^2}{0.0163 m}=1.1\cdot 10^{-10} F](https://tex.z-dn.net/?f=C%3D%281%29%288.85%5Ccdot%2010%5E%7B-12%7DF%2Fm%29%5Cfrac%7B0.210%20m%5E2%7D%7B0.0163%20m%7D%3D1.1%5Ccdot%2010%5E%7B-10%7D%20F)

Answer:
553.1m
Explanation:
When an object moves at constant velocity we can express this movement like V=x/t, where V is the velocity, x is the displacement and t is the time spent on it.
In that way, the expression x=V.t give us the displacement from t=0s until t=51s, but we have to sum the initial distance from the point A.
x=242m +V.t = 242m + (6.1m/s x 51s) = 553.1m
