It is an extension of the grounding system
Answer:
The answer is below
Explanation:
Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:
V = kT, where V = volume and T = temperature, k = constant. Therefore:
V / T = k
Given that: 
The new volume is 3.41 m³. That is it expands by 0.41 m³
d.) a and b only
This is because sound needs a medium to travel. It can travel in a solid (the fastest) and air for example. Sound waves cannot propagate through a vacuum and since space is a vacuum the answer is a and b only.

In vacuum and empty space, it's 299,792,458 meters per second
(186,282.4 miles per second).
In any material stuff, it's somewhat less. How much less depends on
what stuff it is ... it's different in each material "medium".
