Bare free charges do not remain stationary when close together. to illustrate this, calculate the acceleration of two isolated protons separated by 2.00 nm (a typical distance between gas atoms). explicitly show how you follow the steps in the problem-solving strategy for electrostatics.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?
