2H2O->2H2+O2
This balanced chemical equation represents the decomposition of water into hydrogen gas and oxygen gas
Answer:
Push the washing machine harder onto the surface it sits upon, increasing friction between the two.
Explanation:
<h2>
Answer:</h2>
If you triple the charge, the electric potential is 3V.
<h2>
Explanation:</h2>
If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.
<em>But why this is true?</em>
Well, the potential V due to a single point charge q is:
If the strength of the charge is tripled means that our new q1=3q, therefore:
So you can see that in fact if you triple the charge, the electric potential is 3V.
The correct answer is B.
Let us think of the classical theory first. In the classical theory, light is a wave that gives energy. This energy gradually helps the electron jump to a higher energy level.
In quantum theory, this is wrong; an electron cannot absorb a small amout of energy because there is not close enough state to jump to with that energy; only very specific amounts of energy lead to a change in orbital levels/ absorbance of energy. Also, each pair of energy levels has a specific energy difference that is needed from an electron so that it can move.
Hence, B is correct; all other sentences describe classical models of light-electron interactions
