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 the tesla (T).

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
