If a negatively-charged rod is brought close to an electroscope that is negatively charged, what will the two leaves of the electroscope do? move closer together move farther apart not move at all become positively charged

Move further apart

Explanation:

The negative charge on the rod repels the electrons on the cap thus they concentrate at the leaves causing an increase in the amount of charge at the leaves. Since like charges repel, the two leaves of the electroscope move further apart.

  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.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
