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.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
