What happens when a sound wave moves from air to water ?

explanation:

when a sound wave moves from water to air, the speed of the sound wave decreases. this is because the transfer of motion that produces the wave travels fastest through particles that are closely packed together. as water is denser than air, the sound wave moves faster from molecule to molecule.

b. the carbon cycle ensures living things have a source of hydrogen

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
