B. they both involve wave interaction.
Answer:

Explanation:
Average velocity of oxygen molecule at given temperature is

now we have
M = 32 g/mol = 0.032 kg/mol
T = 27 degree C = 300 K
now we have


now for de Broglie wavelength we know that



Well, first of all, EVERY physical quantity is measured in a combination
of 2 or more units, except for mass, length, time, and electric charge.
ALL other units are made out of these. So it should not surprise you.
[ Example: Speed = (length) / (time) ]
Density is not the mass of a substance. It's the mass of a substance in
a standard volume of it. So the density is made of the mass in any lump
and the volume of that lump. That way, no matter how much of a substance
you have, you can always compare the lump you have to all other substances.
Winds are immigrants. They're named for where they have already been and are coming from, not for where they're going.
A Westerly wind is coming from the West. Anything caught in it is being blown toward the east.
