WHO IS GOOD AT PHYSICS, ELECTRIC CIRCUITS?​

Vanyuwa [196]3 years ago

Answer: An electric circuit is a representation of how current moves from the source of the current( example a battery or a cell) through resistors and other devices before entering the source.

Explanation:

The two important types of electrical circuit includes:

--> open circuit and

--> closed circuit.

A circuit is said to be open when the electrical source, such as the battery or the cell, is not connected to any external conductor (or resistance). In this situation, any voltmeter connected across the terminal of the cell measures the total driving force of the cell.

In this type of circuit, current cannot flow from one end of power source to the other due to interruptions.

A circuit is said to be closed if the source of electricity is connected to an external conductor through which current is passed.

In a closed circuit, there is complete electrical connection which allows current to flow or circulate. Here, part of the total driving force of the source is used to drive current through the external resistance and the difference is used to overcome the internal resistance of the battery.

LiRa [457]

Answer:

Equation for SHM can be written

V = w A cos w t        where w is the angular frequency and the velocity is a                                         maximum at t = 0

V1 = w1  A cos w1 t

V2 = w2 A cos w2 t

V2 / V1 = w2 / w1     since cos X t = 1 if t = zero

V2 / V1 = 2 pi f2 / (2 pi f1) = f2 / f1 = T1 / T2

If the velocity is twice as large the period will be 1/2 long

The Position Of A Particle Moving In The Xy Plane Is Given By R= [2.0*cos(3.0t)i+ 2.0*sin(3.0t)j] Where R Is In Meters And T Is
ExtremeBDS [4]

Answer:

Explanation:

We can prove that this is a circular motion if we demonstrate that the norm of the vector is independent of time. Hence we have

R(t)=2.0cos(3t)\hat{i}+2sin(3t)\hat j\\\\|R(t)|=\sqrt{4cos^2(3t)+4sin^2(3t)}\\\\|R(t)|=\sqrt{4(cos^2(3t)+sin^2(3t))}\\\\

but cos^2(3t)+sin^2(3t)=1. Thus we obtain

|R(t)|=\sqrt{4}=2

The norm is independent of t, thus, the particle describes a circular motion

Hope this helps!!

During which two moon phases would the amount of light reflected from the moon appear to be equal from Earth? Why does this occu
shusha [124]

The moon phase shows that D. light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.

<h3>What is a moon phase?</h3>

It should be noted that the <em>moon</em> phase simply means the portion of the moon that we can see from the Earth.

In this case, the light reflected during the first quarter and third quarter moon phases appears equal because the sun, moon and Earth are at right angles.
