Answer:
Rectilinear propagation describes the tendency of electromagnetic waves to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.
The winds normally blow from east to the west rather than blowing from the north to the south in the northern and the southern hemispheres.
<u>Explanation:</u>
The reason for the blowing of the wind from the east to the west rather than from the north to the south in both the hemispheres which are the northern and the southern hemispheres are because it happens in light of the fact that Earth's rotation around it's own axis creates what is known as the Coriolis effect.
The Coriolis impact makes wind frameworks turn counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

if the distance between the objects is doubled the force is reduced by a factor of 4
<h3>Whats is gravitational force?</h3>
Gravitational force is the force of attraction between objects in the universe.
f = G * m1 * m2 / r^2
f = gravitational force
G = gravitational constant
m1 = mass of object 1
m2 = mass of object 2
r = distance between the objects
From the formular, the gravitational force and the distance is an inverse relationship so increasing the distance by a factor results to reduction of the force by the square of the factor. hence doubling the distance which is distance mutiplied by 2 will lead to reduction of the force by 2^2 = 4
Therefore: The force decreases by a factor of 4.
