Einstein used the photoelectric effect to show that light can behave both as a particle and as a wave.
My answer will be C. Law of Original lateral continuity. :)
Kinetic energy has increased.
The <em>Kinetic Molecular Theory</em> of gases states that the average kinetic energy of the molecules of a gas is directly proportional to its Kelvin temperature.
Thus, if the temperature of the air in a room has increased, the average kinetic energy of its molecules has increased.
Which of these what?
This isn't clear, can you put the answer choice or something?
Answer: The transition metals make up the middle block of he periodic table
