According to Newton's first law of motion, what happens to the ball is  the ball rolls backward.

<h3>What is the first law?</h3>

This means that an object at rest or in motion will remain uniformly rectilinear and tend to be in that state if the net force on it is zero.

In this case, we have to think that the ball is at rest and the train is moving with a velocity that way, the reaction of the ball will be to go in the opposite direction to the motion.

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.

Answer this question thanks

Like they said the leopard seal will overpopulate and kill out all of the other animals. Because it would be at the top of the chain then without the killer whale. Therefore, since it is at the top of the chain it will overpopulate because it has nothing to eat/kill it so then they would eat the animals lower than them<span />

Which of the following modifications to a solenoid would be most likely to decrease the strength of its magnetic field?
Goryan [66]

By reading the fine details of the question, carefully and analytically, I have determined that there's no list of modifications to choose from.

The strength of the magnetic field of a solenoid depends on the electric current in its coil windings, the number of wire turns in its coil windings, and the material in its core.

In order to <em>DE</em>crease the strength of its magnetic field, any one or more of these steps could do the job:

-- DEcrease the electric current in its coil windings.  This can be accomplished by decreasing the voltage of the power source that energizes the coil, and/or increasing the resistance of the wire in the coil.

-- DEcrease the number of wire turns in the coil.

-- If the solenoid has anything in its core, change the core to something with a lower magnetic 'permeability'.  An Iron core will produce the greatest magnetic field strength.  Air, vacuum, or NO core will produce the lowest magnetic field strength.
