Ответ:
331.31 m/s
Explanation:
The speed of sound in air is given by,
where γ = ratio of molar heat capacity of the gas (1.401 @ 0 °C)
R = Universal gas constant ( 8.314 J/ molK)
T = absolute temperature (kelvin temperature) (273 K)
M = molar mass of gas (28.97 g/mol)
using these values,
= 331.31 m/s

Equation: -10 40/4^2
Explanation: I multiplied the -10, but idk if that' what you do cause I've never done this. So if you do do that it's -1000, but that is probably wrong. Sorry, I tried.
