Explain what happens to the kinetic energy of the representative particles of a substance as the temperature increases.​

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Which is an advantage of subdividing science into different areas?
