Answer:
Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Explanation:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
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:
yes, radio waves and x-rays are type of light.
increase the strength of the magnetic field when current flows through the circuit
She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.
A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.
