Complete the table by calculating the sprinter’s instantaneous speed for each 1 s time interval. (Hint: To find the average speed in each 1 s time interval, you must know the distance that the sprinter covered in that time interval. Notice, however, that the second column of the table only gives you the total distance that the sprinter had covered by that point in the race.)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
