PHYS 1260 Exam 1 DeWitt questions and answers ,latest updated Just as gravity is the study of a wide range of gravitational interactions, electricity is the study of a wide range of ANSWER>>>electrical interactions Electricity is the name given to a wide range of electrical phenomena that, in one form or another, underlie just about everything around us Electrostatics is a branch of electricity that focuses on ANSWER>>>both electrical charge and electrical force when static AKA static electricity. Electrostatics involves electric charges, the forces between them, the aura that surrounds them, and their behavior in materials. In an electrically neutral atom the number of protons in the nucleus is equal to the number of ANSWER>>>electrons that surround the nucleus Important facts about atoms: -Every atom is composed of a positively charged nucleus surrounded by negatively charged electrons. -The electrons of all atoms are identical. Each has the same quantity of negative charge and the same mass. -Protons and neutrons make up the nucleus. (The common form of the hydrogen atom, which has no neutron, is the only exception.) Protons are about 1800 times more massive than electrons, but they carry an amount of positive charge equal to the negative charge
