Apot of water is boiling under one atmosphere of pressure. assume that heat enters the pot only through its bottom, which is copper and rests on a heating element. in two minutes, the mass of water boiled away is m = 3.5 kg. the radius of the pot bottom is r = 5.5 cm and the thickness is l = 2.0 mm. what is the temperature of the heating element in contact with the pot?

Which statement best describes how private industry decides where to spend the money on research and development

True or false: the revolution of the earth creates day and night as it rotates around the sun

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
