The separation of white light into its component colors is

Physics
1 answer:
Julli [10]3 years ago

<h2>Answer: dispersion</h2>

The dispersion of light occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.

The best known case is when a beam of white light from the sun passes through a prism, thus obtaining rays of different colors like those of the rainbow.

This phenomenom was named by Isaac Newton in the  eighteenth century, who performed the experiment explained above.

Hence, the correct option is C.

A small block of mass M = 0.10 kg is released from rest at point 1 at a height H = 1.8 m above the bottom of a track, as shown i
Ede4ka [16]

Answer:

D

Explanation:

A) is not correct, because the gravitation potential energy will depend on the height the block is located at. It will be calculated with the formula:

U=mgh.

If we take the ground as a zero height reference, then on point 2 the potential energy will be:

U_{2} = 0.10kg(9.81 m/s^{2})(0.6m)

U_{2}=0.59 J

While on point 3, the potential energy will be greater.

U_{3}=0.10kg(9.81 m/s^{2})(1.2m)

U_{3}=1.18 J

B) is not the right answer because the kinetic energy will vary with the height the block is located at in the fact that the energy is conserved (this is if we don't take friction into account or air resistance) so in this case:

U_{2}+K_{2}= U_{3}+K_{3}

We already know the potential energy at point 2. We can calculate the kinetic energy at point 3 like this:

K_{3} =\frac{1}{2}mv_{3}^{2}

K_{3} =\frac{1}{2}(0.10kg)(2.5 m/s)^{2}

K_{3} =0.31 J

So the kinetic energy at point 2 is given by the equation:

K_{2}  =U_{3}-U_{2}+K_{3}

so:

K_{2} = (1.18J)-(0.59J)+0.31J

K_{2} =0.9J

As you may see the kinetic energy at point 2 is greater than the kinetic energy at point 3.

C) Is not correct because according to the first law of thermodinamics, energy is not lost, only transformed. So, since we are not taking into account friction or any other kind of loss, then we can say that the amount of mechanical energy at point 1 is exactly the same as the mechanical energy at point 3.

D) Because of what we talked about on part C, this will be the true situation, because the mechanical energy of the block will be the same no matter theh point you measure it at.

Prove that the rate of heat production in each of the two resistors connected in parallel is inversely proportional to the resis
Viktor [21]
I believe that the answer to the question provided above is that with increase in resistance provided with constant current, Power dissipated will be lessen since power loss is high. Low power dissipation has low heat production.
Hope my answer would be a great help for you.

Suppose the universe were completely empty except for one object- a solid sphere moving through space at a speed of 100km/s. wha
vladimir2022 [97]

Straight linear path

Explanation:

If the universe were completely empty with just one object which is solid moving sphere  through the space at a speed of 100km/s, it will move along on a straight path.

An object will continue on a straight path or at rest unless acted upon by an external force. This is the first law of newton.

  • Since there is no other mass or body in the universe, it will move along in a straight line.
  • Our planet and other bodies moves in parabolic path and elliptical orbits because they are attracted by the gravitational forces of other bodies.
  • Any body with mass will attract other bodies and makes it move round it.
  • The body with the less mass will orbit in the vicinity of the larger mass.
  • But if we have just one body out there, there is no attraction from any other body, it will continue along it's straight path.
