That which travels in waves that are not the same length is called

Which energy-level change shown in the diagram below emits electromagnetic radiation with the longest wavelength?

Andrej [43]

-- Electromagnetic radiation is emitted (spit out) when an electron
moves from a higher energy level to a lower one.

-- The greater the difference in energy between the two levels, the more
energy is emitted, and the shorter the wave;length of the emitted photon.

<span>a) an electron moving from 4 to 5
This electron is moving to a HIGHER energy level. It doesn't emit anything.
In fact, you had to shoot energy INTO the atom to make the electron do this.

b) an electron moving from 5 to 2
This electron loses maybe something like 3.1 eV.

c) an electron moving from 6 to 1
This electron loses maybe something like 13.4 eV.

d) an electron moving from 2 to 1</span>
This electron loses something like 10.2 eV.

The least energy is emitted by the electron in choice-b.
That one will emit the photon with the longest wavelength (shortest frequency).

This whole chart refers to the one electron in a hydrogen atom ...
how much energy it has at each level, how much energy is required
to boost it from one level to another, and how much energy it spits out
when it falls from one energy level to another.

The Balmer Series ... any drop that ends up at energy-level #2 ...
is the set of transitions that produce photons of visible light.

The Paschen Series are transitions that all emit less energy.
All of those emit infrared photons.

The Lyman series are transitions that all emit big energy.
All of those emit X-ray photons.

A large cube (mass = 25 kg) being accelerated across a horizontal frictionless surface by a horizontal force . A small cube mass

belka [17]

Answer:F=400.28 N

Explanation:

Given

mass of large cube $M=25 kg$

mass of small cube $m=4 kg$

coefficient of static friction $\mu =0.71$

acceleration a of the system is given by

$F=(M+m)a$

$a=\frac{F}{M+m}$

Now Normal reaction between two blocks is given by

$N=ma$

friction tries to balance weight

thus $f_r=mg$

and $f_r=\mu N$

$f_r=\mu ma$

$\mu ma=mg$

$\mu \frac{F}{M+m}=g$

$F=\frac{(M+m)g}{\mu }$

$F=\frac{29\times 9.8}{0.71}$

$F=400.28 N$

Please help I have no idea how to do this

rewona [7]

Answer:

So an object with mass is attracted to another object with mass, and the gravitational force is directly proportional to the masses of the two objects, and inversely proportional to the <em>square</em> of the distance between the two objects.

If distance were to increase, than the gravitational force would decrease. If mass were to increase, so would the gravitational force.

Ishmael has an object that produces an electric field. He then places another charged object inside that electric field.

taurus [48]

The increase the magnitude of the electric force ;

1) The charges on the objects must be increased

2) The distance of separation between the objects must be reduced.

<h3>What is electric field?</h3>

The term electric field has to do with the region where the electric force on an object is expirieced. We must the note thate electric force is a result of the influence of a charge on another.
