-is created by vibrations in electric and magnetic fields
-moves in longitudinal waves

Answers

Light is created by vibrations in electric and magnetic fields because the light is an electromagnetic wave, therefore the correct answer is option C

What is an electromagnetic wave?

The oscillation of an electric field and a magnetic field produces electromagnetic waves, which are waves. In other words, electromagnetic waves (EM waves) are made up of vibrating magnetic and electric fields that are orthogonal to one another.

It is undeniable that we experience solar radiation, which is an electromagnetic wave that originates from the sun and can travel through space to the planet.

Light is a form of electromagnetic which is made up of the electric and magnetic filed that are orthogonal to each other, light can travel without any medium.

Thus, Light is created by vibrations in electric and magnetic fields, because the light is an electromagnetic wave, therefore the correct answer is option C

Explain the energy transformations necessary for turning on a Chromebook. Your description should have at least three types of energy being described.You may want to talk about the different parts of the Chromebook,such as:

Plug
Battery
Light

PLZ HELP THIS IS DUE TODAY!!

Answers

Answer:

First, you need to charge the battery.

You do this by connecting the device to the electricity, in this way you can store the energy, that comes in form of electric energy, in the battery, that stores the energy in form of chemical energy.

When you push the "ON" button, the energy stored in the battery starts to run in the device, in form of electrical energy, in this way it reaches all the components and the computer is fully turned on.

At this moment the Chromebook turns on its screen, producing luminous energy (so consumes the electric energy that comes from the battery, and turns it into luminous energy).

There are other transformations, for example, in the cooler (the small fan inside the device) there is a transformation from electrical energy to mechanical energy (because the fan is rotating now).

Suppose you are standing on a skateboard and shoot a paintball gun at your friend. Which direction relative toyour friend will you move? Explain. _

Answers

Answer:

I will move way from my friend.

Explanation:

As I shoot the paintball towards my friend, the gun exerts a force on it that sends it moving towards my friend, and according to newtons third law, the paintball exerts an equal and opposite force on me, which causes me to move in the opposite direction of the movement of the paintball; this direction is away from my friend.
