Which of the sources of error that you cited in question 5 do you think most affected your experiment? Why?
The greatest possible source of error is probably in the measurement of the time
because of problems in determining the moment of starting the timer and the exact
moment the mass hits the floor. Also individual reaction times usually cause rather
large errors.

Why do flat disks form around young stars?
A) They don't; the stars form from the disks. B) Centrifugal force pushes gas outward from the spinning gas cloud. C) Intense winds from nearby massive stars flatten the gas cloud. D) Collisions between rotating gas particles flatten the gas cloud along the axis of rotation.
