Answer:

D.transverse waves move perpendicular and longitudinal waves move parallel to the direction of energy movement

Explanation:

Transverse wave : It is defined as the wave in which the the vibration of the particles of the medium through which the wave travel is perpendicular to the direction of motion of the wave. Example : electromagnetic wave

Longitudinal wave : It is defined as the wave in which the the vibration of the particles of the medium through which the wave travel is parallel to the direction of motion of the wave. example : Sound wave

Which best summarizes a concept related to the work-energy theorem?

Maurinko [17]

Answer:

When work is positive, the environment does work on an object.

Explanation:

According to the work-energy theorem, the net work done by the forces on a body or an object is equal to the change produced in the kinetic energy of the body or an object.

The concept that summarizes a concept related to the work-energy theorem is that ''When work is positive, the environment does work on an object.''

Which disadvantage of nuclear power use poses the greatest threat to the environment?

Mekhanik [1.2K]

The correct answer is The storage and management of radioactive wastes

Explanation:

In general, nuclear reactions (changes in the nucleus of an atom such as fission) release a lot of energy including a lot of heat. Moreover, this heat is used by humans to obtain electricity and other types of energy, which is known as a nuclear power. This type of power is considered positive because it does not emit carbon and it is quite efficient.

However, in most cases, it is a threat to the environment and living beings because storing and managing the wastes of this type of power is difficult and expensive. Indeed, dealing with the wastes of nuclear power requires complex infrastructure, and any accident or leaking leads to serious consequences from the death of those exposed to the wastes to permanent loss of diversity or changes in nearby areas.

LenKa [72]

Answer : The de-Broglie wavelength of this electron, $0.101\AA$

Explanation :

The formula used for kinetic energy is,

$K.E=\frac{1}{2}mv^2$ ..........(1)

According to de-Broglie, the expression for wavelength is,

$\lambda=\frac{h}{mv}$

or,

$v=\frac{h}{m\lambda}$ ...........(2)

Now put the equation (2) in equation (1), we get:

$\lambda=\frac{h}{\sqrt{2\times m\times K.E}}$ ...........(3)

where,

$\lambda$ = wavelength = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

m = mass of electron = $9.11\times 10^{-31}Kg$

K.E = kinetic energy = $4.71\times 10^{-15}J$

Now put all the given values in the above formula (3), we get:

$\lambda=\frac{6.626\times 10^{-34}Js}{\sqrt{2\times 9.11\times 10^{-31}Kg\times 4.71\times 10^{-15}J}}$

$\lambda=1.0115\times 10^{-11}m=0.101\AA$

conversion used : $(1\AA=10^{-10}m)$

Therefore, the de-Broglie wavelength of this electron, $0.101\AA$

What characteristics of EM waves did you discover?

jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
The shape of electromagnetic waves is transverse waves.
It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
The universal constant of the velocity of electromagnetic waves in a vacuum is $\boxed{ \ c = 3 \times 10^8 \ m/s. \ }$
The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

<h3>Further explanation</h3>

Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.
