Question

Which of the following is a reasonable conclusion concerning the measurements of g from the two experiments? (The experiment of the dropped ball and the experiment of the ball thrown upward)

a) The measured value of g from the two experiments agree with each other.

b) In one experiment, the air resistance increases the observed acceleration (magnitude) and in the other experiment air resistance decreases the observed acceleration (magnitude).

c) No two experiments yield the exact same measured value. (The accepted value of g has been determined by making countless measurements using an average value.)

e) b and c, but not a
