The charge on the positive plate is 1.734*
C
Given,
V=9v, R=0.066m Gap(G)=2.0mm=0.0020m ∈=8.85*
We know C=∈ * 
= 8.85* *
=19.275* F
Also, Q = C V = 19.275* * 9 = 1.734* 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.

Answer:
9.0 m/s
Explanation:
The problem can be solved by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
is the acceleration of gravity
t is the time
When the ball reaches the maximum height, the velocity becomes zero. If we consider this as initial point of the motion, we can write
u = 0
The time it takes for the ball to go down from the maximum heigth to the ground is half the total time, so
And solving the formula for v, we find the final velocity:
So, the final speed is 9.0 m/s.
Answer:
It would be C because quantity means numbers
Answer:
D.The potential energy per unit charge
Explanation:
Electric potential of a charged particle:
It is scalar quantity because it has magnitude but it does not have direction.
It is the amount of work done required to move a unit positive charge from reference point to specific point in the electric field without producing any acceleration.
Mathematical representation:
Where W= Work done
= Unit positive charge
Other formula to calculate electric field:
Where K=
It can be defined as potential energy per unit charge.
Hence, option D is true.
Explanation:
The matter passes in the directions of the noise and flows from the source to a receiver like sound flows through a substance. As the sound flows through a fluid, the material is disrupted for an amount of time, but after the sound leaves, it restored to its normal location.
