Astudent on a skateboard is moving at a speed of 1.40 m/s at the start of a 2.25 m high and 12.4 m long incline. the total mass is 48.0 kg, air resistance and rolling resistance can be modeled as a constant friction force of 41.0 n, and the speed at the lower end of the incline is 6.00 m/s. determine the work done (in j) by the student as the skateboard travels down the .

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

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
