Explanation:
Reverberation, in psychoacoustics and acoustics, is a persistence of sound after the sound is produced.[1] A reverberation, or reverb, is created when a sound or signal is reflected causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air.[2] This is most noticeable when the sound source stops but the reflections continue, decreasing in amplitude, until they reach zero amplitude.

Due to rotation of Earth on each day, our East & west gets change in every half day, and comes in it's initial state after a day. So, Stars which are in east relative to a stationary object in the Universe, will be in west relative to Earth after some time, and it changes our view of stars
Hope this helps!
Answer:
v = 6.93 m/s
Explanation:
given,
spring constant = k = 400 N/m
compression of spring = 6 cm = 0.06 m
mass of ball = 0.03 Kg
length of barrel = 6 cm
using energy conservation
KE of ball = PE of spring
v = 6.93 m/s
hence, the speed at which ball leaves the barrel will be equal to v = 6.93 m/s
