Now each of the hairs has the same positive charge. Things with the same charge repel each other. So the hairs try tomove away from each other. The farthest they can get is to stand up and away from all the other hairs.If you walk across a carpet, electrons move from the rug to you. Now you have extra electrons. Touch a door knob and ZAP! The electrons move from you to the knob. You get a shock.Question 1What does it mean for an object tohave an electriccharge?

What is happening when two objects are rubbed together and static electricity results?Question 444How many electrons are there in 2 ×10−5coulombs of charge? Determine the answer without using a calculator, and express the answer in scientific notation!Question 555If a positive charge is forcibly moved closer to another positive charge, mechanical work mustbe performed. This is analogous to compressing a spring: work must be done to cause motion against the natural repulsion of the system:This mechanical work becomes “stored”in the electric field between the charges, and is a form ofpotential energy. This, again, is similar to a mechanical spring, where the work done in compressing a spring is “stored”as potential energy in its compressed state.Definevoltagein terms of the change in potential energy resulting from this forceful motion of the charge, the way a physicist would.Question 1For an object to be electricallycharged, it must have either a surplus or a deficit of electrons among its atoms.Ans. To
A common example ofelectrically charging objectsis rubbing latex balloons against wool clothing, or brushing your hair with a plastic comb. The consequences of these electric charges are very easy to perceive!Question 2There are 6.25 ×1018electrons in onecoulombof charge. What would this appear as without the use of scientific notation? Write this same figure using the mostappropriate metric prefix.Question 3When certain combinations of materials are rubbed together, the rubbing action transfer electrons from the atoms of one material to theatoms of the other. This imbalance of electrons leaves the former material with apositive
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
