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.

A scientist that studies rocks and minerals is called a Geologist. They study the characteristics of rocks to understand Earth's history, predict natural occurrences, and find resources.
A scientist who studies rocks and minerals is known as a Geologist. Geologists use rocks and minerals to help them understand the history of our planet. They study different substances found in rocks such as fossils, metals, and oils to learn more about the earth's past. For instance, by looking at the characteristics of a rock, like its color, texture, and mineral composition, a geologist can predict where resources (like oil, gas, and precious metals) might be found, understand volcanic activities or even predict potential future earthquakes.

Answer:
They make food by using chemosynthesis.
Explanation:
Deep-water bacteria, known as chemoautotrophs, make their own food through a process called chemosynthesis, using chemicals like hydrogen sulfide from hydrothermal vents instead of sunlight.
Some deep-water bacteria in the ocean are known as chemoautotrophs, which can produce their own food by using chemical energy from hydrothermal vents. Unlike plants, they do not use sunlight for photosynthesis. Instead, they rely on chemosynthesis for their energy supply. In this process, bacteria convert chemicals from the vents into usable energy or food. For example, some bacteria use hydrogen sulfide, a chemical abundant in the deep ocean, for chemosynthesis. This biological process allows these deep-water bacteria to thrive in environments where sunlight is not available.

1) C4H8O2
2) C4H12O4
3) C2H10O2
A) CH3O
B) CH5O
C) C2H4O
Answer:
1) C4H8O2 = C2H4O
2) C4H12O4 = CH3O
3) C2H10O2 = CH5O
Explanation:
Answer:
C₄H₈O₂ = C₂H₄O
C₄H₁₂O₄ = CH₃O
C₂H₁₀O₂ = CH₅O
Explanation:
1) C₄H₈O₂ = C₂H₄O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₄/₂H₈/₂O₂/₂ = C₂H₄O
2) C₄H₁₂O₄ = CH₃O
The smallest subscript is 4. So dividing each subscript by 4 we get,
C₄/₄H₁₂/₄O₄/₄ = CH₃O
3) C₂H₁₀O₂ = CH₅O
The smallest subscript is 2. So dividing each subscript by 2 we get,
C₂/₂H₁₀/₂O₂/₂ = CH₅O
