Why does transporting materials during production release carbon dioxide?
-Materials release carbon dioxide as they move around in vehicles.
-Materials exposed to air get warm easily. The warm materials release more carbon dioxide.
-Materials break down as they move and cause pollution. Pollution releases carbon dioxide.
-Vehicles used to move materials consume fuel and release carbon dioxide.

Answer:

They break down quicker than stable isotopes.

Explanation:

I hope this helps

Have a blessed day

The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.

A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.

Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.

Therefore, option C that is, they  break down quicker than stable isotopes is correct.

Answer:

Explanation:

Dalton's Atomic Theory explained a lot about matter, chemicals, and chemical reactions. Nevertheless, it was not entirely accurate, because contrary to what Dalton believed, atoms can, in fact, be broken apart into smaller subunits or subatomic particles. We have been talking about the electron in great detail, but there are two other particles of interest to us: protons and neutrons. We already learned that J. J. Thomson discovered a negatively charged particle, called the electron. Rutherford proposed that these electrons orbit a positive nucleus. In subsequent experiments, he found that there is a smaller positively charged particle in the nucleus, called a proton. There is also a third subatomic particle, known as a neutron.

Protons, neutrons, and electrons are fundamental particles that constitute the building blocks of atoms.

Protons and neutrons are found in the nucleus, the central core of the atom, whereas electrons are located in electron shells surrounding the nucleus. Protons carry a positive electric charge and have a mass of approximately 1 atomic mass unit (amu).

Neutrons, on the other hand, are electrically neutral, meaning they have no electric charge, but they also have a mass of about 1 amu. Electrons, which are much smaller than protons and neutrons, have a negligible mass of approximately 1/1836 amu and bear a negative electric charge that exactly balances the positive charge of protons, resulting in an overall neutral charge for the atom. The combination of these three particles determines an element's chemical properties and behavior in chemical reactions.

If my skater begins at a height of 5 meters, then the skater will have enough total energy to successfully complete the skate park ramp from start to finish

Brainliest me

If my skater begins at a height of 5 meters, then the skater will have enough total potential energy to successfully complete the skate park ramp from start to finish.

If my skater starts at a height of 5 metres, he or she will have enough total potential energy to complete the skate park ramp from beginning to end. Potential energy is a physics notion that is affected by an object's height and mass. Because of its position in a gravitational field, an object at a specific height above the earth has potential energy.

The skater has a particular amount of potential energy connected with their starting height of 5 metres. As they go down the ramp, this potential energy is turned into kinetic energy, or motion energy. As the skater moves down the ramp, their speed rises, as does their kinetic energy.

The digestive tract carries out the function of peristalsis by moving food through the system.  Peristalsis also removes excess liquid from the body.  Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis.  Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

Answer:

•  Friction is a force that occurs when two surfaces slide past

one another.

• The force of friction opposes the motion of an object,

causing moving objects to lose energy and slow down.

• When objects move through a fluid, such as air or water, the

fluid exerts a frictional force on the moving object. The

frictional force from a fluid is called a drag force.

• Friction examples: tires skidding to a stop on a road,

sandpaper rubbing against wood, air pushing against the

nose of an airplane

• Friction drag force causes objects to slow down as they move through a

fluid, such as air or water.

• Drag force depends primarily on the following variables:

– Cross‐sectional area of an object moving through the fluid

– Speed of moving object

– Density of the fluid

– Drag coefficient (determined by experiments; related to the shape of

the object)

• Drag force is especially dependent on the speed of an object. As an

object’s speed increases, the drag force from the fluid increases

exponentially.

• For example, when you drive at high speeds, the frictional force of air on

the car increases and fuel economy decreases

Answer:

if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity

The greater the force that is applied to an object of a given mass, the more the object will accelerate

Explanation:
