Explanation:
The observations are as follows: Initially with the plates in the dark, no electrons pass between the plates and no current flows. As we shine light on the plates, going from low energy red to high energy blue, suddenly current begins to flow. How?
Einstein explained the result be describing the light waves as packets of energy. He called the packets of energy photons. Each photon has a specific energy, the shorter the wavelength, the higher the energy. When a high-energy photon hits the plate (such as a green or blue), the photon has enough energy to knock out an electron and then the electron, being negative, will fly to the positive side. At this point, current flows.
The lower energy photons are unable to know out the electrons and no energy can flow.
The exciting thing to note is the treatment of energy as a particle or a packet, it is consistent with the fact energies are not additive. If we can bump electrons with light at 600 tera-hertz , we can�t just use 300 tera-hertz for twice the time and still expect to bump electrons.
What if the photon has greater than the threshold energy required to pop out an electron? The extra energy just goes into the kinetic energy of the electron. This relationship can be described by the following equation.
hf = w + KE
where hf is the energy of the photon.
w is the energy required to bump an electron.
KE is the kinetic energy of the electron.
If the photon has less energy than w, no electron is emitted.
Increasing the brightness of light for red, yellow, orange, and green colors can cause a metal to absorb more energy and potentially undergo physical or chemical changes such as expansion or emitting light of a certain color.
Increasing the brightness of the light for the colors red, yellow, orange, and green will affect the metal in different ways depending on the specific metal being used. Generally, metals will absorb some of the energy from the light and convert it into heat. This increase in heat can cause the metal to expand, change its color, or undergo other physical or chemical changes.
For example, when a metal is exposed to bright light, it may heat up and expand, leading to changes in its shape or dimensions. Additionally, depending on the metal and its properties, the increased brightness of light can lead to certain metals absorbing specific wavelengths of light, which can cause the metal to emit photons and exhibit a characteristic color.
In summary, increasing the brightness of light for red, yellow, orange, and green colors can cause a metal to absorb more energy and potentially undergo physical or chemical changes such as expansion or emitting light of a certain color.

Answer:
1.01 x 10^24 molecules
Explanation: This problem is solved by remembering Avogadro's number and since we have the mass of CO, we can easily calulate the number of moles.
Molecular Weight CO : 28.01 g/mol
47.2 g * 1mol / 28.01 g = 1.68 mol
Now 1 mol of CO is 6.022 x 10^23 molecules ( Avogadro's Number) then
1.68 mol CO * 6.022 x 10^23 = 1.01 x 10^24 molecules
Answer:
Explanation: Sediments or sedimentary rocks are formed from pre-existing rocks broken through the agents of denudation such as air, ice, water flow which carries the particles and deposits it, the accumulation of one layer on the others is called DEPOSITION. As the deposits keeps building, LITHIFICATION occurs which involves overburden pressure acting on the sediments in layers.
Note that during deposition oldest layers are below, while the younger layers are above
atm
to
torr
To convert atm to torr, we should know 1 atm equals 760 torrs then the conversion exists 2052 torr.
Torr and atmare the two main pressure units. To convert atm to torr, we should know 1 atm equals 760 torrs.
It exists the manometric pressure unit. It exists described as, the pressure exerted by column of mercury one millimeter high it exists represented by mmHg.
Torr to mmHg conversion:
Both exists equivalent to each other.
1 torr = 1 mmHg
Torr to atm:
Torr exists converted into atm by dividing the torr value 760.
mmHg to atm.
mmHg exists converted into atm by dividing the torr value 760.
Kilopascal:
The kilopascal exists the unit of pressure. It exists denoted by KPa.
Given:
2.70 atm
The conversion exists given by,
1 atm = 760 torr
2.70 atm = 760 × 2.70 torr
= 2052 torr
Therefore, the correct answer is 2052 torr.

Explanation:
multiply the pressure value by 760
Answer: The correct answer is C) it's phenotype.
Phenotype corresponds to the morphological form or physical appearance of an organism. It is depicted due to the genotype (genetic makeup) of the individual.
In other words, phenpti is related to the physical traits or specific characteristics of the individual.
Therefore, it describes how an organism looks (such as eye color, hair color, skin color).
Thus, C) is the right answer.
