An open pipe of length l is resonating at its fundamental frequency. which statement is correct? a. the wavelength is 3l/2 and there are two displacement antinodes located inside the pipe. b. the wavelength is l and there is a displacement antinode at the pipe's midpoint. c. the wavelength is l and there is a displacement node at the pipe's midpoint. d. the wavelength is 2l and there is a displacement node at the pipe's midpoint. e. the wavelength is 2l and there is a displacement antinode at the pipe's midpoint.

explanation:

newton's third law, for every action there is an equal and opposite reaction.

0.19 m/s and 0.45 m/s

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.
