The electric field inside a parallel plate capacitor is given by:
E = Q/(ε₀A)
E is the electric field, Q is the charge stored on one of the plates, and A is the area of one of the plates.
The plates are circular, so the area A of one of the plates is given by:
A = πr²
where r is the radius.
Therefore the electric field is given by:
E = Q/(ε₀πr²)
Given values:
E = 3×10⁶N/C (max E field allowed before breakdown occurs)
r = 54×10⁻²m
Plug in these values and solve for Q:
3×10⁶ = Q/(ε₀π(54×10⁻²)²)
Q = 2.4×10⁻⁵C
Neuron and muscle cells have plasma membranes that undergo voltage changes in response to stimuli.
<h3>What is a neuron?</h3>
Neurons are messengers of information.
Between various brain regions and between the brain and the rest of the nervous system, information is transmitted using electrical impulses and chemical signals.
A neuron has a cell body that includes a nucleus and cytoplasm, from which long, thin hair-like structures emerge.
The axon, a solitary long component of the neuron, is responsible for carrying the nerve impulse to various body areas.
The dendrites are the neuron's small, branching body sections.

Answer:
12 N
Explanation:
Use Newton's second law:
∑F = ma
F = (2.4 kg + 1.3 kg) (3.2 m/s²)
F = 11.84 N
Rounded to two significant figures, the force is 12 N.
In your question where the ask is to calculate the charge that the small sphere carries which is the mass of it is 441g moving at an acceleration of 13m/s^2 nad having and electric field of 5N/C. So the formula in getting the charge is mutliply the mass and the quotients of Acceleration and the Electric Field so the answer is 1,146.6
To solve this problem we will apply the concepts related to classical mechanics, for which we will first consider the general equation that describes the movement of the body. From there, as we well know, we will obtain the derivative, which is equivalent to the speed of the body and the rate of change that is investigated in the problem.
Our values are given as,
We will start by defining the general height 'y' of the body at a reference distance of the lifting copter, given as
Differentiating both the sides we have
Now when the altitude of the copter is 124ft we have that
And,
Using these values at the derivative equation finally we have that
Therefore the distance between the man and the helicopter is increasing at the rate of 40.68ft/s
