The famous scientist Galileo Galilei did several experiments with sloping planes, which he rolled metal balls down so that he could study motion. By changing the slope, he could study how the speed at which the ball rolled was affected.
What was one thing Galileo would have needed to control himself to make sure his experiment gave him useful information?
A. the speed of the ball
B. the slope of the plane
C. the pull of Earth's gravity
D. the material the ball was made of

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
