Question

The density of the atmosphere at sea level is 1.29kg/m3 and g=9.8m/s2 .assume that both do not change with altitude .how high should the atmosphere extend?

Answer 1

use formula, $P=\rho gh$

where P is atmospheric pressure,

$\rho$ is density of atmosphere.

g is acceleration due to gravity.

here given, $\rho$ = 1.29 kg/m³ ,P = 1.013 × 10^5 N/m² and g = 9.8 m/s²

h = P/$\rho$g = 1.013 × 10^5/(1.29 × 9.8)

≈ 8013 km

hence, atmosphere extended 8013km high from the sea level.

Answer 2

Answer:

Explanation:

d=hpg

d=1.29 kgm^-3 × 10 m/s^2

h=1.29 kgm^-3 × 1000 kgm^-3 ×10 m/s^2

h=1.29×10×1000

h=7989m

h=8 km
