Two identical insulated metal spheres are equally charged and separated by a distance of 0.1 m. The resulting force between the spheres is 8.1 x 10-8N. -What is the force if the size of each charge is tripled? Show your calculation.

-What is the force if the distance between the spheres is doubled? Show your calculation.

Why do different substances have diffrent properties

Formulating a hypothesis: part i since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of " because when writing your hypothesis

Imagine that the rightward current flows in the rod for a short time. as a result, what will the net charge on the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral
