Using the simulation above, write a paragraph to describe what happens to the positively charged alpha particles when the positive charges in the atom are concentrated and diffuse. Is there a difference when
you change the distance? Why or why not?

Ahollow metal sphere has 6 cm and 11 cm inner and outer radii, respectively. the surface charge density on the inside surface is −100nc/m2. the surface charge density on the exterior surface is:

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
