Mechanical waves travel slowest in which physical state?

Mechanical wave travels slowest in gases.

Explanation:

Mechanical wave is a wave in which there is a oscillation of the matter. Therefore, there is a transfer of the energy through the medium.

The wave travels over long distances. Mechanical waves are of two types: Longitudinal wave and Transverse wave. Mechanical wave requires a medium to travel. It can travel in the solid, liquid and gases.

It travels fastest in solid and slowest in the gases due to the packaging of the molecules of the state. The molecules of the gases are not tightly packed so therefore it is hard for the particle to transfer energy.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
