Why write numbers in scientific notation
understanding physics will you describe in great detail how the world works. however, the characteristics of the worldspan an enormous range of numbers. the mass of an electron is 0.911 (incredibly the mass of the sun is 1,989,000,000,000,000,000,000,000,0 00,000 (incredibly if you hadto write, interpret, or use these numbers as written, you could very easily end up making a minor math error. scientificnotation was invented to easily express numbers that are too large or too small to be conveniently written in decimal form. the advantages of scientific notation are it 1) is compact, 2) articulate significant figures, and 3) works with numbersof any size. the traditional format for numbers written in scientific notation is 10is where is a number between 1 and 10 and is an integer (either positive or negative). for the examples above, the mass of an electron can be written as 9.1110-31and the mass of the sun can be written as 1.9891030

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
