During the motion of the slinky in a transverse wave, what do the particles of the slinky coil do?Question 3 options:

the slinky particles move from the hand down the wave to the block


the slinky particles move side to side


the slinky particles move up and down

Answers

Answer 1
Answer:

The characteristics of the traveling waves we can find the correct answer for the movement of the particles in the transverse wave is:

  • The slinky particles move up and down.

The traveling wave movement is a way of transmitting energy without mass movement, it is formed by two movements united, an oscillatory movement and a displacement movement, there are two possibilities:

  • Longitudinal wave. In this case, the oscillation of the particles is in the same direction as the movement of the wave.
  • Transversal wave. The oscillation of the particle is perpendicular to the movement of the wave, see attached.

In both cases, the matter particles are oscillating around their equilibriumposition and the wave is the one that has a displacement movement.

Let's review the claims:

a) False. The particle has an oscillatory motion, it does not have a net displacement

b) False. The movement is oscillatory

c) True. As the wave is transversal, the oscillatory movement from top to bottom.

In conclusion using the characteristics of the traveling waves we can find the correct answer for the motion of the particles in the transverse wave is:

  • the slinky particles move up and down

What is the importance of the ozone layer?

Answers

Importanceofozonelayer:

  • The ozone shields the surface of the earth from ultraviolet UV radiation from the sun.
  • These radiations are highly damaging as they can cause cancer in both plants and animals, damage to eyes and immune system.
  • They can also lead to variations in global rainfall, ecological disturbances and dwingling of global food suppliers.

Explanation:

Formationofozonelayer:ozone at the higher level of the atmosphere is a product of UV radiations acting on oxygen O2 molecule. The higher energy UV radiations split apart some molecular oxygen( O2) into free oxygen (O) atoms.

Depletionodozonelayer:The amount of ozone in the atmosphere began to drop sharply in the 1980's . This decrease has been linked to synthetic chemicals like cholorofluorocarbons ( CFC's ) which are used as refrigerants and in fire extinguishers.

Ok I'm doing physics gragh an I don't know how to find the impulse on a graph

Answers


OK instead of telling us what you don't know, it would actually be much more helpful if we could talk about what you DO know.

What is it a graph of ? 

-- Impulse is (force applied) x (time the force persists).
Is there force or time anywhere on the graph ?
Is there acceleration anywhere on the graph, and do you know the mass ?
With acceleration and mass, you could calculate the force.

-- Impulse is also the change in momentum.
Is there momentum anywhere on the graph ?
Is there speed anywhere on the graph, and do you know the mass ?
With speed and mass, you can calculate the momentum.

We can use what you know to solve the problem.  But we cannot use
what you don't know to solve the problem.

I just had the coolest idea:  What if you took a picture of the Physics gragh
that you're doing, and post it here along with your question ? !  Then we
would have the same information that you have, and we could show you
how to use it.

Maurice directs a beam of light on a sheet of glass at an angle of 51°. What is the angle of refraction in the glass? The refractive index of glass is 1.46.A: 22 degrees
B: 29 degrees
C: 32 degrees
D: 36 degrees

Answers

Answer:

Angle of refraction in the glass is 32 degrees

Explanation:

It is given that,

Maurice directs a beam of light on a sheet of glass at an angle, θ₁ = 51°

The refractive index of the glass is, n₂ = 1.46

We know that the refractive index of the air is, n₁ = 1

We have to find angle of refraction in glass i.e. θ₂

According to Snell's law :

(n_1)/(n_2)=(sin\ \theta_2)/(sin\ \theta_1)

Putting all the values we get :

(1)/(1.46)=(sin\ \theta_2)/(sin51)  

\theta_2=sin^(-1)((sin(51))/(1.46))

\theta_2=32\ ^0

Hence, the correct option is (c) " 32 degrees ".  

Maurice directs a beam of light on a sheet of glass at an angle of 51°. The refractive index of glass is 1.46. The angle of refraction in the glass is 29 degrees. The answer is letter B.

Answers

Answer: Motor convert most of its electric energy into mechanical energy.

Explanation:

An electric motor is an electric machine which converts electric energy into mechanical energy.

Electrical energy → Mechanical energy.

The principle on which it works is that when current carrying conductor is placed under the influence of magnetic field it experiences force which termed as mechanical force.

Why does the number 54,289.00 have seven significant figures and not five

Answers

the 2 spots after the decimal still counts toward the total  the figures 

thought it was 5 at first too. the 00 past the decimal at significant because it's expressing it is exactly to that point. sort of confusing.
say you measured a pencil with a ruler, and say it was 5" long roughly. you can only scientifically put down that the pencil is 5 inches not 5.0000 because your ruler doesn't go that many decimal places. when something is absolute is the only time you can add .0000000000000000000000 to it and it still be correct. an example of something that is absolute is like you have 10 fingers, 10 is absolute because it's exact 10.0000000000000000=10 fingers it's not any more and not any less.
Those two zeros are included after the decimal so they aqre significant. The rule is all final zeros after the decimal are significant
Since there is a decimal point present, start with the leftmost nonzero didgit. Count that digit and every other digit to the right of it.
