Answer: Decreases
Explanation:
By definition, absolute zero temperature defines the temperature at which the atoms of a material no longer transmit thermal energy.
Engineering materials can transmit thermal energy at higher temperatures by random molecular motion.
It follows that as the temperature decreases toward absolute zero, random molecular motion decreases.
The sound is perceived as louder if the amplifier increases, and softer if the amplitude decreases.
I think the answer is (C.) but im not sure
acceleration equals to the force applied divided by mass
an object moving at a velocity of x carries the force of its mass times its speed.
when you apply a force onto an object, the increase in speed of it would be affected by its mass. Think of it this way: you apply some force onto an iron ball, and apply the same force on a plastic ball (they are of equal volume). Which one moves faster, and which one moves slower? The answer is obvious: the iron ball will accelerate slower and travel slower, while the plastic ball is faster.
The iron ball has a greater mass, so the force which makes it accelerate is deduced more. The plastic ball has a smaller mass, so the force applied is divided by a smaller number.
I hope this helps you a bit.
