Question

The atmosphere accounts for:

a. 3% of the total mass of the planet 0.5% of the total mass of the planet

b. 0.000003% of the total mass of the planet 0.08% of the total mass of the planet

c. 0.0025% of the total mass of the planet

d. 0.00009% of the total mass of the planet

Answer 1

D

Step-by-step explanation:

Weight of atmosphere would apply pressure on Earth's Surface

P = F/A

P=Atm pressure , F= force , A= area

Let mass M

M x g / A = P

g= 9.81 m/s^2

A is the surface area of a sphere = 4 x π x r^2

r= radius of earth

Putting values

`M*9.8/4*3.14*(6.37*10^6)^2 =1.013*10^5`

∴ M = 5.26 x 10^18 Kg

We know that total mass of Earth is 6×10^24 Kg.

Therefore we can say that The atmosphere accounts for:0.00009% of the total mass of the planet. Option D is correct.
