The distance versus time graph for Object A and Object B are shown. A graph titles Distance vs Time. A straight slanting line is drawn through point 7 on y axis and this line is labeled Object A. The graph for Object B is a straight slanting line passing through the origin

What is the similarity between Object A and Object B?

Both have the same slope.
Both move with variable speed.
Both move with constant speed.
Both start the journey from the same point.

The correct answer is - Both move with constant speed.

Explanation:

If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.

The relation between the variables x,t, and v is

x=v.t

If V is constant which is the speed we get a straight line x-t in the graph.

By the given information we can say that both objects A and B are traveling at a constant speed.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
