Electricity and magnetism are separate yet interconnected phenomena. Which of the following options BEST supports the idea that
the electricity and magnetism are interconnected? (A) Electricity is the phenomenon of electric charges, whether they are stopped or moving.
(B) When a particle is stationary or stopped, it has an electric field, yet if the charge is moving, it also generates a magnetic field.
{C) Any magnetic particle or object has a "north" and "south" pole, with the directions based on the orientation of the Earth's magnetic field.
(D) Magnetism, like electricity, also has associated units of measurement, such as Tesla (T).
Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline.
It’s B. Sound travels faster through solids than liquids. Have you ever put your head on a desk, and tap the desk? That’s an example of it going faster through solids
