According to the law of conservation of energy, energy is not created or destroyed. it changes form or is transformed. what energy transformation(s) is/are depicted here? a) electrical energy ⇒ light energy b) potential energy ⇒ kinetic energy ⇒ light energy c) chemical energy ⇒ electrical energy ⇒ light energy d) chemical energy ⇒ electrical energy ⇒ heat and light energy

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

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
