Answer: Albert Einstein
Explanation:
Light can be considered as a wave or as particles, in this context Einstein proposed that light behaves like a stream of particles called <u>photons</u> with an energy, in order to correctly explain the photoelectric effect (in fact he won the 1921 Nobel Prize in Physics because of this explanation).
To uderstand it better:
The photoelectric effect is a fenomenom that consists in the emission of electrons that occurs when light falls on a metal surface under certain conditions.
This can only be explained based on the corpuscular model of light, that is, light is quantized.
So, Einstein theorized light as a stream of energy packets called photons, this energy is able to pull an electron out of the crystalline lattice of the metal and communicate, in addition, a kinetic energy.
To solve this problem it is necessary to apply the concepts related to heat exchange and Entropy.
The temperature and mass remain constant, therefore the entropy values will be the only ones to change.
Of the three elements given their entropy values are given by
Part A) From thermodynamic theory we know that temperature is inversely proportional to entropy
Energy remains constant
Therefore the order would be
Lowest Temperature= Water
Medium Temperature= Glass
Highest Temperature=Iron
Part B) In the case of Energy the opposite happens because it is proportional to the entropy, then
Temperature is constant
Lowest Energy = Iron
Medium Energy = Glass
Highest Energy = Water
Answer:
1. :uniformly accelerated motion
2. .0m/s
All we can say is that the object's volume is about 41 liters. That's the same as the volume of water displaced.
We can't say anything about the object's weight. There is no direct connection between the weight of the object and the weight of the water it displaces.
F = ma, where m is the mass of the body and a its acceleration.
So F = 39x7.8 = 280.8 N
