Agerman scientist, george ohm, discovered the relationship between current, voltage, and resistance. this became known as ohm's law. according to ohm’s law, if v is voltage, i is current, and r is resistance, their relationship is expressed by the equation a) i = v/r b) i = v × r c) i = v + r d) i = v – r

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.

Why is a noble gas different from other elements

Asign is hung between two cables as illustrated below. if the sign weighs 350 n, what is the tension (in n) in each cable?
