Find the speed of sound in pure nitrogen from its bulk modulus and its density.

251.38 m/s

Explanation:

Let us assume that the gas is undergoing an isothermal process

So B = Partial pressure of nitrogen

B = 79033.5 Pa

ρ = Density of nitrogen = 1.2506 kg/m³

Speed of sound

Speed of sound through pure nitrogen is 251.38 m/s

the closer the planet is to the sun, the larger the gravity

force tends to be low and long diustance masses are high
