The length of a vector arrow represents its magnitude and the point represents its direction
true or false
apex

The answer is: True.

The magnitude of a vector is represented by the length of the arrow.

The arrow length is drawn according a chosen scale.

For example, the diagram shows a vector with a magnitude of 100 kilometers, if the scale used for constructing the diagram is 1 cm = 10 km, the vector arrow is drawn with a length of 10 cm.

The arrow has an obvious tail and arrowhead. The arrow points in the precise direction.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
