Explain how to identify a starting position on a line.

A position vector expresses the position of an object from the origin of a coordinate system.

Explanation:

Position vector is basically a straight line which has one of its ends end fixed to a body and whereas, the other end is attached to a moving point which tells the position of that specific point relative to the body. As the point accelerates, the position vector will vary its length and the direction accordingly.

Pick a reference point on the line to be the zero position. Determine the direction and measure the distance from zero in standard units.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
