Newton's third law of motion relates to action and reaction. which of the following scenarios accurately names the correct action and reaction pair to apply to newton's third law? a. a skateboard moving (action) after being pushed (reaction) b. an ax being used to hit wood (action) and the wood splitting after being hit by the ax (reaction) c. a car accelerating forward (action) after the driver pushes the acceleration pedal (reaction) d. an arrow hitting a tree (action) after being launched (reaction

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

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34
