What is the traditional definition of gravity?
Answer:
A force of attraction between things that have mass. Gravity can act between objects that are not even touching. In fact, gravity can act over very long distances. However, the farther two objects are from each other, the weaker is the force of gravity between them.

I, II, III and IV
Answer:
grass
Explanation:
it is a plant, hope this helps
Answer:
Only I
Explanation:
rabbits and foxes are not plants so it does not go through photosynthesis (they eat food to get their energy instead) . A mushroom is a decomomposer that breaks things down to get it's energy thus make the grass the only plant that goes through photosynthesis.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.
Answer:
The total amount of carbon in the world is not changing. Because matter is
conserved in all processes and reactions, carbon must decrease in one place if it increases in another.

Which of the following statements is true?
Like magnetic poles attract each other
There is no relationship between magnetic poles
Like magnetic poles repel each other
Answer:
Like magnetic poles repel each other
Explanation:
Among the following statements, the one that is true is Like magnetic poles repel each other.
What are magnets?Magnets are substances which possess their own magnetic field this magnetic field basically arises from the circular movement of negatively charge electrons. The elements which have unpaired electrons and have spin angular momentum or orbital angular momentum or they are together present are called as Magnets.
The magnetic field present is invisible but it is definitely responsible for the most notable property of a magnet. Magnetic force is a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
Therefore, Among the following statements, the one that is true is Like magnetic poles repel each other.

Explanation:
Increase the brightness of the light for the colors red, yellow, orange, and green. What effect did the brightness of the light have on the metal?
(science)
make me brainliest
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.
If the inclination angle is 15 how does the path of the Sun in the sky change as the planet moves from the right side of its orbit to the left?
Answer:
There is no change in the angle at which sunlight strikes the ground. When the inclinatio n angle is 23 degrees, the longest sunlit period is about 15 hours, and the shortest is about 9 hours.
Explanation:
Scientists claim that climate change is happening because Earth is warming. They also claim that humans have helped cause the warming by adding greenhouse gases to the atmosphere. Other people claim that Earth is not experiencing climate change because some winter days are still very cold. Use evidence to evaluate each claim about climate change.
help
this is science.
Answer:
There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.
Explanation:
Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.
What is global warming?Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.
Evidence which claim about climate changeGreenland, Antarctica, and tropical mountain glaciers have all provided ice cores that illustrate how the Earth's climate responds to fluctuations in greenhouse gas levels. Tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks all contain ancient data.Yes, 97 percent of actively published climate scientists agree that people are to blame for global warming and climate change.Based on the data, nearly 97 percent of climate scientists agree that human-caused climate change is happening, according to the American Association for the Advancement of Science (AAAS).To know more about Global warming here

Explanation: genetically modified organisms (GMOs) are being made by inserting a gene from an external source such as viruses, bacteria, animals or plants (etc) into foods. Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah

Choose the two statements that apply.
A. Clothing is hung outside on a day when the temperature is below the freezing point of water. The clothes dry, even though they freeze first.
B. An ice cube melts on the floor, then it evaporates.
C. Bromine is a reddish brown, liquid element. In a closed container, a reddish brown gas exists above the surface of the bromine.
D. Dry ice changes directly to carbon dioxide gas
Sublimation is the process by which solids are instantly transformed into gases. The forces of attraction between solids are completely defeated when they absorb enough energy. Solids, such as dry ice, undergo sublimation.
What is sublimation?Similar to melting, freezing, and evaporation, sublimation is a form of phase transition, or change in a state of matter. Without ever entering a liquid phase, a substance transforms from a solid to a gas through sublimation. Typical sublimation examples include dry ice, which is solid CO2,additional elements that cannot be sublimated. A solid-solid combination is separated by sublimation when one of the components sublimes (transforms from solid to gaseous state without producing liquid) following heating, leaving the other non- sublimable components behind.Sublimation is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase in between. Sublimation is an endothermic phase transition that occurs at temperatures and pressures lower than a chemical's triple point in the phase diagram.To learn more about Sublimation refer to:
