The speed of sound i gases depends on a humidity b air c temperature d visibility

The speed of sound in gases is represented mathematically as:

v(sound)  = √γRT/M

where γ = adiabatic constant which is the ratio of the heat capacities at constant pressure and constant volume; Cp/Cv

R = gas constant

T = temperature

M = molar mass of the gas

Hence, the speed of sound in gas is directly proportional to the square root of temperature.

Ans: c) temperature

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

b.
