An object of the same mass has three different weights at different times. which statement is possible?

the object gains matter and then loses it.

the object started on earth, was transported to space, and was deposited on the moon.

the object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill.

the object changes shape, which changes its weight.

the answer is b

  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.
