If the time in a distance/time graph is written like '12 noon' and '1pm' etc and not like 30 minutes, 40 etc how do we calculate the average speed then? divide the distance by what kind of time?

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
