Electromagnetic waves carry energy. This phenomenon is also called electromagnetic radiation. How is energy transferred in electromagnetic waves?
A)
Energy is transferred as the electric and magnetic fields regenerate each
other.
B)
Energy is transferred through the magnetic component of the
electromagnetic wave.
9.
Energy is transferred through the electric component of the
electromagnetic wave.
Energy is pushed from one point to the next along with the moving
electromagnetic wave.
D)

A15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°c to 175°c. what is the specific heat capacity of iron?

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.
