An example you could use for this would be if you threw a pencil across the room 10m away. the pencil would have travelled 10m(N). you could determine the objects speed by using the formula speed=distance/time. you would have had to time how long it took for the pencil to hit the 10m marking and divide 10 by however many seconds it took.

You connect a 9V battery to a capacitor consisting of two circular plates of radius 0.066 m separated by an air gap of 2.0 mm. W

mel-nik [20]

The charge on the positive plate is 1.734* $10^{-12}$ C

Given,

V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85* $10^{-12}$

We know C=∈ * $\frac{A}{G}$ = 8.85* $10^{-12}$ * $\frac{\pi *0.066^{2} }{0.002}$ =19.275* $10^{-12}$ F

Also, Q = C V = 19.275* $10^{-12}$ * 9 = 1.734* $10^{-12}$ C

<h3>Charge </h3>

When charged matter is exposed to an electromagnetic field, its electric charge—a property of matter—causes it to feel a force. A charge on an electric field might be positive or negative. Like and unlike charges are attracted to one another while being repelled by the other. Neutral describes a thing without any net charge. Electric charge is a conserved property; in an isolated system, the net charge, or the sum of the positive and negative charges, is constant. Subatomic particles transport electrical charge. The protons in atoms' nuclei carry positive charge in normal matter, while the electrons carry negative charge.
