A scuba diver wants to signal to someone standing on the shore of a lake. If the diver is 1.2 m below the lake's surface, at what angle in degrees, relative to the normal, should the diver shine a flashlight beam in order for the person to see it. The index of refraction for water is 1.33.

the area between the graph and the t axis

  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.
