Normally, an atom has an equal number of protons and electrons. So the positive charge (protons) and the negative charge (electrons) evens out. But electrons on the outer edges of an atom can be more loosely attached, so they can be transferred to another atom. When this happens, and an electron is lost, or transferred, to another atom, the original atom has a net charge.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap
