Energy stored in a stretched spring is U. It is cut in two equal parts. If one part is now stretched to
the same extension, energy stored in this part is
(1) U
(2) 2U
(3)U/2
(4) 4U

scientific laws are the result of testing theories and proving them to be facts.

  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.
