I) Do both the cyclists start at the same point? If not, who is ahead at the starting point? ii) At t = 7s, which cylclist is lagging behind? iii) Which cyclist – A or B would be travelling with greater speed? How can you justify?

Answer and Explanation:

Assuming the image attached is the distance/displacement-time graph of both cyclists A and B:

I hope this explanation was easy to understand and helpful.

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.
