Answer: The frequency of the electromagnetic wave is equal to the oscillation frequency of the electron is the correct option.
Explanation:
Electromagnetic waves are created by oscillating charges. Frequency of waves and oscillation of electron both are the same. Electromagnetic waves are always move perpendicular to the direction in which the wave moves.
Answer:
That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
Answer:
i would say B? Im sorry if im wrong
Explanation:
i think that because Catabolic reactions release energy, while anabolic reactions use up energy. Anabolism is the opposite of catabolism.
Answer:
Explanation: in exothermic reaction heat is released out
In endothermic reaction heat is absorbed
<span>The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases. you can look it up in Google</span>
