Consider two planets in space that gravitationally attract each other. if the masses of both planets are doubled, and the distance between them doesn't change, then the force between them is

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
