The property of air mass include
1) it must be large.
2) it must have relatively uniform properties.
3)it must travel as a recognizable entity.
It must have a warm front at its leading edge, is not necessarily a property of an air mass because Not all air masses have a warm front at their leading edge. There are five types of air masses and different types of the front can be developed.

Friction is the force that acts on an object and opposes its motion
So....
imagine the x and y axis or draw it on a piece of paper, a white board or even on your wall if you like. I'm kidding just draw it on a piece of paper
50m up and 20m down
the dog's displacement is 50 - 20 which is 30
your answer is 30m north
Answer:
F = 2.6 x 10⁻²² N
Explanation:
According to the Coulomb's Law, the force of attraction or repulsion between two charges is directly proportional to the product of the magnitudes of both the charges and inversely proportional to the square of the distance between them. The formula for the force is given as follows:
F = k q₁ q₂/r²
where,
F = Force of Attraction or Repulsion = ?
q₁ = magnitude of first charge = charge on electron = 1.6 x 10⁻¹⁹ C
q₂ = magnitude of second charge = charge on proton = 1.6 x 10⁻¹⁹ C
k = Coulomb's Constant = 9 x 10⁰ N m²/C²
r = distance between the charges = 885 nm = 8.85 x 10⁻⁷ m
Therefore,
F = (9 x 10⁹ N.m²/C²)(1.6 x 10⁻¹⁹ C)(1.6 x 10⁻¹⁹ C)/(8.85 x 10⁻⁷ m)²
<u>F = 2.6 x 10⁻²² N</u>
