To solve this problem it is necessary to apply the concepts related to the change of Energy in photons and the conservation of energy.
From the theory we could consider that the energy change is subject to
Where
Initial Energy
Energy loses
Replacing we have that
Therefore the Kinetic energy of the electron once it has broken free of the metal surface is 0.8eV
Bouta catch these free points lmaoooo hey grace Im right next to you lololololol
BUT HEY YALL WE NEED THIS ANSWER ASAP
Answer:
25
Explanation:
I looked at it and its 25
<span>C) It does not change. At the point where the phase of a substance changes, there is no temperature change but only the phase change. After this, the temperature then goes up or down depending on the type of phase change occurring. </span>
