2. a biologist measures the speed of a swimming amoeba. the amoeba covers a distance of 17.36 microns in 30 seconds. the biologist wished to compare the speed of the amoeba with the speeds of other animals, but the speeds of other animals are listed in kilometers per hour. what is the speed of the amoeba in kilometers per hour? (1 micron = 1 × 10–6 m) use scientific notation, and express your answer to the correct number of significant figures. you
must show your work for full credit.

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
