<h3><u>Answer;</u></h3>

B.wrap more coils of wire around the nail

<h3><u>Explanation;</u></h3>
  • <em><u>Electromagnets are made by winding a wire through a magnetic material such as soft iron core making a coil, and then passing electric current through the coil thus making the soft iron core magnetic.</u></em>
  • <em><u>The strength of the electromagnet depends on the number of coils and also the size of the electric current through the coil.</u></em>
  • Therefore, in this case wrapping more coils of wire around the nail increases the strength of the electromagnet.

"A positively-charged particle is held at point A between two parallel metal plates. The plate on the left has a net positive ch
defon

Answer:

Explanation

A positively charged particle produces a positive electric potential while a negatively

charged particle produces a negative electric potential.

Given two parallel plates one is positive and the other is negative and a positively charge particle is place at point A.

The electric potential V at point P is the algebraic sum of the electric potentials contributed by the two parallel plates charges

V=Kq1/r+ Kq2/r

Since q1 is positive and q2 is negative and they have the same magnitude q.

Then, at position A,

Let assume the total distance between the parallel plate is x

Then, the positive plate should be at distance 'a' from, the other is at x-a.

V= Kq/a-kq/(x-a)

V=kq(1/a-1/(x-a))

V=kq(x-a-a/a(x-a))

V=kq(x-2a)/(ax-a^2)

Then, at position B

Let assume the total distance between the parallel plate is x

Then, the positive plate should be at distance 'b' from, the other is at x-b.

V= Kq/b-kq/(x-b)

V=kq(1/b-1/(x-b))

V=kq(x-b-b/b(x-b))

V=kq(x-2b)/(bx-b^2)

Close to the positive plate, the

potential has very large positive values. Close to the negative charge, the potential has very large negative values.

They have different potential.

What happens to the force between charged and uncharged objects as the distance between them decreases?
MaRussiya [10]

Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

Hope this helps have a awesome night/day❤️✨

Explanation:

Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.

(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)

So a better question would then be, what is gravity’s relationship with an electric field?

You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)

Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

A go cart with a mass of 60 kg is moving at a rate of 10 m/s. How much Kinetic Energy does the go cart have?
maria [59]

Answer:

<h2>3000 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass in kg

v is the velocity in m/s

From the question

m = 60 kg

v = 10 m/s

We have

k =  \frac{1}{2}  \times 60 \times  {10}^{2}  \\  = 30 \times 100 \\  = 3000

We have the final answer as

<h3>3000 J</h3>

Hope this helps you

Which of the following is an example of an even population distribution?
icang [17]
Even population distribution refers to a type of population distribution in which the arrangement is done in such a way that the distance between neighboring individual is maximized and uniform. This type of population distribution is usually found on the farm land, where the space in which the crops are planted have been carefully measured out. Thus an example of even population distribution is corn planted in a field.
