Answer:
While In an <em><u>ideal/isolated</u></em> system, as long as the object is not in motion, its potential energy will be the same.
However, <u>potential energy is relative</u>. On Earth, usually, it is measured with respect to gravity. <u>The higher the object, the greater the potential gravitational energy</u>. It's all relative. For the sake of this question, I would assume that potential energy increases.
Explanation:
While kinetic energy depends upon speed, potential energy is always relative to some arbitrary reference point.

Answer:
The distance between two posts
Explanation:
As the students have already measured the amount of time necessary for the wave to oscillate up and down that is on the string between two posts,They have to measure the speed of the wave.
ie v=fλ
<em>They have to measure distance between the posts.
</em>
Because wavelength is equal to the distance between the posts ie full length of string.
The frequency of the wave is calculated by
f=
1/T
Where is the time period which the students have calculated ie the amount of time taken to oscillate up and down,
Thus the wave speed is calculated using formula
v=λ/T
