Which of these is not a resistor?a. wire
b. light bulb
c. hair dryer
d. all of these are resistors

Answers

The correct answer is (d.) all of these are resistors. A resistor creates the reduction of the current flow and voltage levels within the circuits. A wire is a resistor because it is made up of alloy and carbon that helps to maintain a low resistance and have an easy flow of the electric charges. Same as the light bulb and the hair dryer, they all reduce the current flow.

As a longitudinal wave travels through a medium, it displaces the particles . parallel to the direction which the wave travels.b. along the opposite plane of travel.
c. vertically along the direction that the wave travels.
d. perpendicular to the path of travel.

Answers

As a longitudinal wave travels through a medium, it displaces the particles parallel to the direction which the wave travels.

What is longitudinal wave?

This type of waves are vibrations that takes place in the same direction i.e parallel to the wave motion. They are usually mechanical and examples include sound waves which requires a medium.

A longitudinal wave is a form of wave in which the displacement of the medium and the medium's vibration are both parallel to the direction of the wave.

A longitudinal wave moves the particles parallel to its direction of passage as it passes through a material.

Explanation:

The potential difference between two points, A and B, in an electric field is 2.00 volts. The energy required to move a charge of 8x10^-19 coulomb from point A to point B is

Answers

The energy required to move the given charge from point A to point B is of $1.6 * 10^(-18) \;\rm J$ .

Given data:

The potential difference between the points A and B is, V' = 2.00 V.

The magnitude of charge is, $q = 8 * 10^(-19)\;\rm C$ .

The given problem is based on the work done to shift a charge from one point to another.

When a charge is moved between the two points, then some work is to be done, which gets stored in the form of electrostatic potential energy.
And the mathematical expression for the electrostatic potential energy is,

W = U

W = q × V'

Solve by substituting values as,

$W = (8 * 10^(-19)) * 2.00\n\nW = 1.6 * 10^(-18) \;\rm J$

Thus, we can conclude that the energy required to move the given charge from point A to point B is of $1.6 * 10^(-18) \;\rm J$ .

Answer:

$W_A_B=-1.6* 10^(-18) J$

Explanation:

Let A and B be two points located in a uniform electric field, A being a distance d from B in the direction of the field. The work that an external force must do to bring a unit positive charge q from the reference point to the point considered against the electric force at constant speed, mathematically is expressed by:

$V_B_A=(W_A_B)/(q)$

Therefore, isolating $W_A_B$ and replacing the data provided:

$W_A_B=V_B_A *q=-2*(8* 10^(-19)) =-1.6* 10^(-18)J$
