For this we need to use several formulas:
v = a*t
This simply means that after 1 second we will have some speed and if we double time, speed will double as well.
But, relation time-traveled distance isn't linear. Traveled distance we calculate:
s = 1/2*a*t^2 we can say that h=s
so if we double time, traveled distance will increase 4 times because of square relation between time and traveled distance.
New traveled distance (h2) will be: h2=4*h
b) Because distance depends on gravity acceleration in free fall h2 will certainly change but the relation h2=4*h will remain the same.
Medium.
Medium is matter, and electromagnetic waves do not need matter to travel. Just like the sun, its plasma light travels across space to reach us.

Answer:
The guitarist should increase the tension of the string.
Explanation:
The frequency of a vibrating string is determined by fn=(n/(2L))√T/μ. So if the tension in the string increased, the rate at which it vibrates (the frequency) will also increase.
Therefore it is advisable that she increase the tension of the string.
