The process by which a gas changes to a solid is

Answers

Answer 1
Answer:

The correct answer to the question is - Deposition i.e the process by which a gas changes to a solid is called deposition.

EXPLANATION:

There are various thermal processes of state or phase change in which matter in one state is converted into matter in another state.

Deposition is the type of thermodynamic process of state or phase change in which a gaseous substance is directly converted into corresponding solid substance without entering into liquid phase.

During this process, the loss of thermal energy from gas is very fast. Hence, the gas directly enters solid phase without undergoing into liquid phase.

This process is just the opposite process of sublimation where a solid is converted into gas directly. That's why this process is also known as desublimation.

For instance, conversion of water vapor into ice.

Answer 2
Answer: That process is called deposition.

If you know the distance an object has traveled in a certain amount of time you can determine

Answers

With that information, you can determine the object's speed.
Just divide the distance covered by the time to cover the distance.

If you also know the direction the object moved, then you can
determine its velocity.  If you don't, then you can't.
You can determine the velocity it is moving at. 

A current is always developed in the secondary of a transformer. true or false

Answers

false. only when supply 'alternate' current in the primary.

The main difference between a series and a parallel circuit is thata. more components can be added to a parallel circuit.
b. the voltage source for a series circuit can be weaker.
c. in a series circuit there's only one path for current to flow.
d. a parallel circuit can handle components with higher resistances.

Answers

c) is correct

series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.

parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.

The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence, such as _____.

Answers

Answer:

Movement of Galaxies away from us.

Explanation:

Big Bang theory is the most widely accepted theory which says that the universe started with a huge expansion, it was not an explosion. By that logic everything must be moving from each other even today. This was proved by observing the Redshift in the spectrum of the galaxies which means that they are moving away from us.

What is BEST to say about a runner who is running at a constant velocity? A. Their acceleration is positive. B. Their acceleration is negative. C. Their acceleration is zero. D. Their acceleration cannot be determined.

Answers

The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer.

the correct answer is C.
