First is ! the material or substance that a wave moves through is called a . the medium affects the speed of the wave that passes through it. one factor that affects the speed of a wave is the of medium. some waves move faster in solids and some waves move faster in liquids and gases. another factor that affects wave speed is the of the medium.

The material or substance that a wave moves through is called a medium. The medium affects the speed of the wave that passes through it. One factor that affects the speed of a wave is the type of medium. Some waves move faster in solids and some waves move faster in liquids and gases. Another factor that affects wave speed is the temperature of the medium. 

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

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.
