To develop this problem we will use the concepts related to Speed in a string that is governed by Tension (T) and linear density (µ)
Our values are given as:
Replacing we have that the velocity is
From the theory of wave propagation the average power wave is given as
Where,
A = Amplitude
Angular velocity
Replacing,
Therefore the amplitude of the wave should be 0.0165m

Really long we’ll not long but far in distance
The star with apparent magnitude 2 is more brighter than 7.
To find the answer, we have to know about apparent magnitude.
<h3>What is apparent magnitude?</h3>
- 100 times as luminous as a star with an apparent brightness of 7 is a star with a magnitude of 2.
- The apparent magnitude of bigger stars is always smaller.
- The brightest star in the night sky is Sirius.
- The brightness of a star or other celestial object perceived from Earth is measured in apparent magnitude (m).
- The apparent magnitude of an object is determined by its inherent luminosity, its distance from Earth, and any light extinction brought on by interstellar dust in the path of the observer's line of sight.
Thus, we can conclude that, the star with apparent magnitude 2 is more brighter than 7.

B. Elastic potential to kinetic energy
The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
