 the one with the greatest mass always has more kinetic energy. so the answer is D
Simora [160]4 years ago

The answer is D. According to the formula of kinetic energy, E=(1/2)*m*v². When the speed of these objects are the same, the object with the maximum weight has the greatest kinetic energy.

Objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blu
7nadin3 [17]

Light from the galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.' As the objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift, most galaxies in the universe exhibit redshift, i.e., option D.

<h3>What are redshift galaxies?</h3>

Most other galaxies are moving away from others since 1929, when Edwin Hubble discovered that the Universe is expanding. Light from these galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.'

Redshift is the displacement of an astronomical object's spectrum toward longer (red) wavelengths. It is attributed to the Doppler effect, which is a change in wavelength caused by the motion of a given source of waves and an observer with respect to each other.

As objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift. It shows that most galaxies in the universe exhibit redshift.

Thus the correct option is D.

Write 16 facts about the carbon cycle
mario62 [17]

-Some objects can store carbon for many years and are known as carbon sinks.

-Carbon in the air is attached to oxygen and is known as a molecule called carbon dioxide.

-Plants use carbon dioxide in the air to make their own food through a process called photosynthesis.

-When plants die and decompose, they could eventually become a fossil fuel and be burned to return as carbon dioxide in the air.

-Carbon dioxide in the atmosphere is helpful because it helps keep our planet at a livable temperature.

-The ocean takes up quite a bit of carbon dioxide to provide nutrients for its plants.

-Living substances that contain carbon are known as organic.

-Carbon is the second most abundant substance in living organisms behind water.

-Humans can obtain carbon in the carbon cycle by eating plants or eating animals that eat plants.

-Roughly 99% of carbon is stored deep within the Earth’s surface.

-Carbon is so important that there is an entire branch of chemistry dedicated to it called organic chemistry.

-Carbon is very versatile in that it can combine with up to four other elements at the same time and can exist as a solid, liquid, or a gas.

-Carbon-14 dating is a technique used to determine the age of ancient artifacts and fossils.

-Carbon is number 4 on the most abundant elements in the universe list.-

-The origin of the word carbon comes from the word carbo which is Latin for coal.

TRUE OR FALSE
luda_lava [24]

Answer:

The correct answer is - true.

Explanation:

Popular genetics is the study of genetic diversity which is having several hypotheses and theories about genetic diversity and mutation of a particular genome.

The selection of such mutations in a genome occurs due to diversification. This postulates that due to the different environmental conditions two subpopulations of a species can have different alleles o a specific locus of the genome.
