I believe it is the very first one
hope it helps :)
Answer:

Explanation:
Graham’s Law applies to the diffusion of gases:
The rate of diffusion (r) of a gas is inversely proportional to the square root of its molar mass (M).

If you have two gases, the ratio of their rates of diffusion is

The time for diffusion is inversely proportional to the rate.

Data:
t₂ = 222 s
t₁ = 175 s
M₁ = 28.01
Calculation
:

There are three specific types of stress.
Compression occurs when pressure pushes in on an object from opposite sides this happens slowly.
Tension occurs when pressure pulls on opposite sides of an object, causing it to stretch this happens quickly.
shear occurs when two objects try to slide past each other in opposite directions this happens not to fast but not to slow.
