What is radiation?????????????

Answers

Answer 1

Answer:

Radiation is the emission of energy through space in the form of particles and/or waves. Nuclear reactions are very different from chemical reactions. In chemical reactions, atoms become more stable by participating in a transfer of electrons or by sharing electrons with other atoms.

Answer 2

Radiation is said to be the transfer of heat between two objects without any medium between them , that can help them in heat transfer . Hence radiation is said to be the direct transfer of heat between two objects . For example the heat we get from the sun can be said to be from radiation as there is nothing between us and the sun that is helping the sun's heat reach us . The sun's heat reaches Earth directly . This is an example of radiation; which is a type of heat transfer .

What are the organelles in the cell?

I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.

Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.

Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.

Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.

Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.

Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

a. Describe a likely result of this chemical reaction that allows a hot air balloon to rise.
b. Describe a design feature the distance a hot air balloon can travel. Explain your reasoning.

Answers

Fueled by propane cylinders, gas jets produce the hot air that fills the envelope (similar to ones you might use on a portable camping stove).

WorkingSince heated air rises, hot air balloons are functional. with the rest. As though it were floating in water, the balloon rises as a result of this. The balloon naturally starts to slowly deflate if the air is allowed to cool.The molecules in the air start to migrate and spread out as the air within the balloon is heated, which results in a decrease in the air's density. The heated air is pushed below the cooler, surrounding air. the warm air is pushed upward as a result of this.

Newton's Laws of Motion

Explanation:

1st- Inertia- every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

2nd- The second law states that the greater the mass of an object, the more force it will take to accelerate the object

3rd- action reaction- If the forces are equal in opposite directions, the object will not move. The forces cancel each other out so that the acceleration is zero. If one force acting in one direction is greater than the force acting in the opposite direction, the object will move.

Answers

Ocean currents are large-scale movements of water within the ocean, driven by a combination of factors such as wind, temperature, salinity, and the Earth's rotation.

What conclusions can be drawn about how salinity and temperature affect water flow?

As water becomes colder, it becomes denser and sinks, while warmer water rises to the surface. Similarly, as the salinity of water increases, its density increases, and it sinks, while less salty water rises to the surface. These density differences create circulation patterns, such as ocean currents and deep water circulation, which can have a significant impact on the distribution of heat, nutrients, and other important factors in the ocean environment.

An evidence-based claim that can be drawn from this information is that changes in temperature and salinity can have significant effects on the flow of water in the ocean. For example, if temperatures in a particular region of the ocean were to increase, it could potentially cause the water to become less dense and rise to the surface, which could disrupt ocean currents and affect the distribution of nutrients and other important factors. Similarly, changes in salinity, such as those caused by freshwater influx from rivers or melting ice, could also affect the density of ocean water and impact circulation patterns.

2. When substances are mixed together, you can see each individual component


3. When substances are mixed together, the mixture assumes the physical properties of each individual substance.


4. Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Answers

Answer:

4) Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Explanation:

Mixtures contain different substances with different physical properties, such as boiling point, melting point, solubility, density, and so on. These properties can be used to separate the individual substances in the mixture through various techniques. For example, distillation is a separation technique that relies on differences in boiling points of the substances in a mixture. When a mixture is heated, the substance with the lower boiling point will vaporize first, and it can be collected and cooled to form a pure substance. Similarly, other techniques such as chromatography, filtration, and crystallization also rely on differences in physical properties to separate mixtures.

On the other hand, chemical changes involve the rearrangement of atoms within a substance, resulting in the formation of a new substance with different properties than the original. While chemical changes can be used to synthesize new substances, they are not typically used to separate mixtures.

1. Find the volume ( cm3) of oxygen in: a. 1000cm3 of air b. 50 cm3 of air.

Answers

Answer:

A. 210 cm³

B. 10.5 cm³

Explanation:

It is important for us to note that air contains 21% of oxygen, O2. With this idea in mind, let us answer the questions given above.

A. Volume of air = 1000 cm³

Volume of O2 in air =.?

Percentage composition of O2 in air = 21%

Volume of O2 = 21% x 1000

Volume of O2 = 21/100 x 1000

Volume of O2 = 210 cm³

Therefore, the volume of O2 in 1000 cm³ of air is 210 cm³.

B. Volume of air = 50 cm³

Volume of O2 in air =.?

Percentage composition of O2 in air = 21%

Volume of O2 = 21% x 50

Volume of O2 = 21/100 x 50

Volume of O2 = 10.5 cm³

Therefore, the volume of O2 in 50 cm³ of air is 10.5 cm³.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.

Answers

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

No it would not conduct electricity as it is a insulator

explain the difference between the 3 types of galaxies

barred spiral galaxies

Answers

There is quite a big difference between a barred spiral galaxy and an elliptical galaxy.

The image attached below shows a barred spiral galaxy, NGC 2217. In barred spiral galaxy there is large bar like structure across the core of the galaxy , and on the terminal end there are the spiral arms of the galaxy. It is believed that the bar plays a role of material transportation to the core. The bar funnels in the surrounding material toward the SMBH at the core. The arms of the barred spiral galaxy often host high star formation rate as seen in the image below. The bar is often consist of dust and old stars.Where as in elliptical galaxy, the galaxies are somewhat diffused and also they don’t host much of the new stars. Elliptical galaxies are often unbounded. Elliptical galaxies are believed to be formed from several mergers and that’t the reason for their inability to form new stars.
