Which statement best explains the relationship between the electric force between two charged objects and the distance between them?As the distance increases by a factor, the electric force increases by the square of that factor.

As the distance increases by a factor, the electric force increases by twice that factor.

As the distance increases by a factor, the electric force decreases by twice that factor.

As the distance increases by a factor, the electric force decreases by the same factor.

As the distance increases by a factor, the electric force decreases by the square of that factor.

Answers

Answer 1

Answer: According to Coulomb's Law. The relationship between the electric force between two charged objects and the distance between them is:
F = 1/d^2

So,

As the distance increases by a factor, the electric force decreases by the square of that factor.

Have researchers have now been able to cool substances to absolute zero

Answers

It's a law of nature, which I don't understand too well, that we can
cool things as close to Absolute Zero as we want to, but we can
never get all the way there.

I think that individual atoms and molecules have been cooled in
the laboratory to within a few thousandths of a Celsius degree
of it ... actually not too shabby an accomplishment !

The 1997 Nobel Prize in Physics was awarded to a team of three
physicists who invented a method of using lasers to slow down the
motion of atoms, and that's the same thing as cooling them. They

When we say that an object wants to maintain its state of motion, we’re talking about inertia. Which term determines the quantity of inertia for an object?

Answers

Inertia is determined by the mass of the object. greater the mass an object has, greater will be its inertia. smaller the mass an object has, smaller will be its inertia. Greater mass enables an object to resist change in its state of motion or rest while on the other hand smaller mass object can be easily made to change its state of motion or rest.

and object has mass, so if moving, has a momentum value.

The least common shape for a galaxy is ______. irregular elliptical cluster spiral spherical

Answers

Answer: cluster

Explanation:

There are four main shapes of galaxies: spiral, galaxies are divided into four main groups: spiral, lenticular, elliptical, and irregular, elliptical, and irregular.

The least common shape is cluster

Spiral galaxies- These are the most common. These have arms extending from a bright bulge in spiral shape.

Elliptical galaxy have ellipsoidal shape.

Lenticular galaxies - Intermediate between elliptical and spiral galaxies.

Irregular shape- No well defined shape

Spherical - Nearly spherical galaxies. These are least

cluster- group of galaxies having irregular shape is the least common shape.

Question: The least common shape for a galaxy _____.

Answer:Cluster

A reaction that requires free energy:a. must be endothermic.
b. is nonspontaneous.
c. must correspond to a decrease in entropy.
d. is spontaneous.

Answers

A reaction that requires free energy is spontaneous. The answer is letter D. this is because it does not any external energy to apply unto it to make the reaction happen. It just happens by itself that is why it is spontaneous.

which unit of measure would scientist use to measure the thickness of rock layer, created as a result of volcanic activity

Answers

A scientist would use a unit of length appropriate for the magnitude of what he or she is measuring. In this case, since rock is built up very slowly, they would probably use millimetres or centimetres. In some cases they may use meters.

There you go.
