Preston goes on a camel safari in africa. he travels 5km north, then 3km south and then 1km north again. what distance did he cover? what was his displacement?

Distance: 9 km

Displacement: 3 km

Explanation:

Distance takes into account the entire path that, in this case, Preston walked, while displacement, considers only the difference between the initial and final point.

In the picture, the different paths represent as a whole the distance he covered (5+3+1), whereas, the start and final point represent displacement (3-0)

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
