A projectile launch test is carried out with the same firing speed of 200 ft / s, the first is fired at 53o above the horizontal and the second is fired with a delay of two seconds at 90o above the horizontal.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
