A parallel plate capacitor fully charged to voltage V is connected to the battery (the voltage on the plates remains fixed). If
Papessa [141]

Charge will decreases.

A parallel plate capacitor when it is fully charged to voltage V is given as:

                    C = Q/V

The capacitance of parallel plate capacitor with two plates of Area A separated by distance d and no dielectric material between plates is

                    C = ε₀ A /d

since from above equation it shows C is proportional to Q and also C is inversely proportional to distance d.

So, ATQ when d increases C will decrease which in result decreases charge on the capacitor.

Thus,  Charge will decrease.

An electron de-excites from the fourth quantum level to the third and then directly to the first. Two frequencies of light are e
4vir4ik [10]

Answer:

The answer is explained below.

Explanation:

The energy emitted during the de-excitation of an electron from a higher energy level to a lower energy level is directly proportional to the frequency of the emitted light.

Here, the total sum of the energies of 2 frequencies of light emitted in different stages is equal to the energy of a single frequency of light during the de-excitation of fourth level to ground level directly.

Hence the total sum of of the frequencies of 2 lights emitted in different stages is equal to the frequency of single frequency of light emitted during the de-excitation  from fourth level to ground level directly.

The some of the energies of 2 frequencies emitted by one electron is equal to the energy of a single frequency when electron jumps directly.

a current of 1.80 a flows in a wire. how many electrons are flowing past any point in the wire per second?
liubo4ka [24]

Any point in the wire has 1.12 x 10^{19}. electrons flow per second.

<h3>What causes a current in a wire?</h3>
  • Electric current in a wire, where electrons serve as the charge carriers, is a measurement of the amount of charge that moves through any point of the wire in a given amount of time.
  • A free electron is drawn to a proton to become neutral if an electron is added to the wire.
  • Lack of electrons can result from pushing electrons out of their orbits.
  • Electric current is the name given to the constantly moving electrons in wire.

The current is the quantity of charge Q flowing through a certain point of the wire in a time interval of \Delta t.

I = \frac{Q}{\Delta t}.

by using this relationship

I=1.80 A, we can find the charge passing any point in the wire in 1 second:

Electric Charge, Q = 1.80 C.

To find how many electrons corresponds to this charge, we should divide this value by the charge of a single electron

charge of the electron = 1.6 x 10^{-19} C.

No. of Electrons = Q/q = \frac{1.80}{1.6* 10^{-19}}= 1.12 x 10^{19}.
