Me : ( which pair of atoms will form an ionic compound? a) one atom of oxygen and two atoms of fluorine b) one atom of calcium and two atoms of chlorine c) one atom of nitrogen and three atoms of fluorine d) two atoms of nitrogen and four atoms of oxygen

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

  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.
