A pipe that is 0.92 m long and open at both ends vibrates in the second overtone with a frequency of 584 Hz. What is the speed of sound in the air in this pipe

362.08 m/s.

Explanation:

The formula for the second over tune of an open pipe is

F = 3v/2l Equation 1

Where F = frequency of the third over tone, v = velocity of sound in air, l = length of the pipe.

Make v the subject of the equation,

v = 2Fl/3 Equation 2

Given: F = 584 Hz, l = 0.93 m,

Substitute into equation 2

v = 2×584(0.93)/3

v =  362.08 m/s.

Hence the speed of sound in air = 362.08 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.
