Answer:
Explanation:
Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.
Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.
scale = 
= 
= 
scale = 1:40
This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.
The man's direction is
north of east.
The graphical drawing of the vector is herewith attached to this answer.
Answer:
This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.

Answer:
Explanation:
Force between two charges is given by coulomb's law as follows
F = 
Where Q₁ and Q₂ are two adjescent charges at distance d.
Putting the given values in the equation we have
=
[/tex]
= 13.1 N
This will be attractive in nature so it will act in - ve x- direction.
