Astudent stays at her initial position for a bit of time, then walks slowly in a straight line for a while, then stops to rest a while, and finally runs quickly back to her initial position along a straight line. which of the following statements is true about the average speed and the magnitude of the average velocity of the student during her trip? her average speed is greater than the magnitude of her average velocity. her average speed is the same as the magnitude of her average velocity. her average speed is less than the magnitude of her average velocity. the student's average speed and velocity cannot be compared without knowing the farthest point she reached.

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
