Answer:
Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom.
Answer:
standard unit of measurement provides a reference point by which objects of weight, length or capacity can be described.
Answer:
Force(N)= Mass(kg) x Acceleration(m/s^2)
Explanation:
The stereo uses an energy of

in a time

, therefore the power of the stereo is given by

We also know that the power of an electrical device is related to its voltage, V, and its resistance, R, by the following equation

therefore, we can rearrange the equation to calculate the resistance of the stereo:
