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.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
