A spotlight in jewellers shop shines light on a diamond ring at an angle 30 degree to the perpendicular. At what angle is the light refracted through the stone?

another example of kinetic energy would be,

kinetic energy   >     moving energy

1 the 4 is sig

c. newton's third law of motion

  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.
