There are two sound waves in the same medium - wave A and wave B Wave A has a frequency of 4 Hz and an amplitude of 50 cm. Wave B has a frequency of 2.5 Hz and an amplitude of 50 cm. Which wave is likely to have the greatest speed? a. Wave A
b. Wave B
c. Both waves have the same speed
d. Cannot be determined

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

going in opposite directions

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
