Asonic boom is produced by a jet. what can you determine about the jet's motion?
a) it is near a mountain where echos can be produced
b) its engines produced backfire
c) it is increasing in altitude
d) it is traveling faster than the speed of sound

Option d) It is traveling faster than the speed of sound

Explanation:

A sonic boom is a sound that is produced as a result of the shock wave produced by an object travelling faster than the speed of sound. When a plane travels through air, it produces waves. If a plane is travelling slower than the speed of sound, then the sound waves propagate ahead of the plane. If the plane breaks the sound speed barrier, then a sonic boom is head when it flies past. The boom is a disturbance of the plane sound waves as it breaks the speed of sound.
