. Two students are performing an experiment where they roll a golf ball
down a
shallow ramp that runs along the back wall of their classroom. The top end of the
ramp rests on a small stack of 4 textbooks and the bottom end rests on the floor. The
ramp is about 6 meters in total length. The students start the ball at rest from the
top, upper third, middle and lower third of the ramp. They measure the time required
for the ball to reach the bottom of the ramp after it is released. They calculate the
speed of the ball at different points on the ramp. Their data is remarkably consistent
from trial to trial. The summary of the ball's speed at various points on the ramp is
shown in the chart below.
Off ramp
Which of these conclusions are best supported by the data represented here?
A)The ball experiences equal increases in speed in equal amounts of
time as it rolls down the ramp.
B) The ball maintains a constant speed as it rolls down the ramp.
C) The ball experiences greater increases in speed in equal amounts
of time as it rolls down the ramp.
D) The ball experiences lessening increases in speed in equal
amounts of time as it rolls down the ramp

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.
