Use the passage to answer the question.
Studentka2010 [4]

This is not something that waves do because they need a medium to travel through, while particles do not.

<h3>How light travels in space?</h3>

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.

How is a flywheel constructed to maximize its rotational inertia?
BigorU [14]

Answer:

It is constructed with a high mass and a high raidus.

Explanation:

The rotational inertia I for every object is calculated as:

cMR^2 = I

where c is a constant, M is the mass of the object and R the radius of the object.

So, for a flywheel, the rotational inertia is calculated as:

I = \frac{1}{2}MR^2

Then, for constructed a flywheel with the maximun rotational inertia we have to set the maximum mass and the maximun radius.

The first charge is pulling on the second. Is the second pulling on the first? Explain your reasoning
Alex73 [517]

Answer:

law of action and reaction.

Explanation:

In Newton's three laws it is established that forces act in pairs, if one body interacts with another the second interacts with the first, this is the so-called law of action and reaction.

In this case, when the first load pulls on the second, the second pulls on the first, the two forces are not canceled because each one is applied to a different body.

Therefore the magnitude of the forces is the same, but the direction is opposite and each one is applied in a body
