Saturn’s rings consists of tiny ice particles, each of them moving in the circular orbit about the planet. all answers in this problem should be given in hours. (a) find the orbital period of particles in the innermost part of the d-ring. (b) find the orbital period of particles in the outermost part of the f-ring. (c) find the orbital period of particles that would orbit in the position of the cassini gap. compare that value to the period of saturn’s moon mimas. how do you comment on that result?

What is the length x of the side of the triangle below? (hint: use the cosine function)

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
