The electric field at any point in the region between the conductors is proportional to the magnitude Q of charge on each conductor. It follows that:
"The potential difference Vab between the conductors is also proportional to Q"
If we double the magnitude of charge on each conductor, the charge density at each point doubles, the electric field at each point doubles, and the potential difference between conductors doubles; however, the ratio of charge to potential difference does not change. This ratio is called the capacitance C of the capacitor:

Given that:

and
Lastly, the capacitance is given by:
Answer:
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
Explanation:
We have equation of motion
S = ut + 0.5at²
Here u = 0, a = g and t = 9.3 s
We have equation of motion v = u +at
Substituting
v = u +at
v = 0 + 9.8 x 9.3 = 91.14 m/s
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
Answer:
Va is two times greater than Vb
Explanation:
The maximum height reached by the balls are:

Since we are told that Ya = 4Yb:

Simplifying the equation:


Answer:
<u>Gravitational Force</u> is a force that attracks two objects with mass. For example, you are being pulled onto this planet, and that's why when you jump upwards, you fall back down quickly. A fun fact is that every object, even the entire universe, are pulling all on each other, including you!
