In the Earth's mantle, hot magma near the core rises up and heats up the magma near the crust. How does the heat transfer from bottom of the mantle to the top?

Conduction

Convection

Radiation

None of the above

Answer:

The freezing point of a substance is the same as that substance's melting point. At this particular temperature, the substance can exist as either a solid or a liquid. At temperatures below the freezing/ melting point, the substance is a solid.

Explanation:

edge 2021

Answer: The relationship between freezing point and melting point is that freezing point is at the temperature of when a liquid freezes and melting point is at the temperature when a solid melts which are both at the same temperature

Some quotes from the text to support this is that: "Freezing point is the temperature at which a liquid freezes and melting point is the temperature at which a solid melts.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.

Answer:

Radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis because radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and use the data for processing and analysis. These radio light waves, that are raw analog signals, are converted into digital signals to create and distinguish delicate details in the universe.

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

Answer:by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery

Answer:

C

Explanation:

scientists usually focus on one specific problem, rather than a whole range. so the answer would be that it's too wide a focus.

btw this is where the crown is on the bottom of the question

Answer:

c

Explanation:

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.

Answer:

8.47 x 10^3

Explanation:

So since we only want 3 sig figs we have to round our last digit up and then it is 10^3 because we moved the decimal place to the left 3 times to get 8.47

Comment if you have any other sig fig questions, happy to answer them!

Answer:

mass is the answer

Answer:

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

Answer:

the law of conservation of matter

Explanation:

The mass of hydrogen is conserved during cellular respiration as it follows the Law of Conservation of Matter.

The Law of Conservation of Matter states that the reactants must equal the products, which is demonstrated through the equation that demonstrates cellular respiration.

C6H12O6 + 6O2 -> 6CO2 + 6H20

This shows that hydrogen has been conserved throughout the entire process (H representing Hydrogen) as the product has the same amount of hydrogen as the reactants.

Not a straight up answer, but moreover to help you get it: (Circuit Boards)

Aside from the tasks it performs, perhaps the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated. Also, circuit boards are less expensive than other options because they can be designed with digital design tools and manufactured in high volume using factory automation.

Partially straight up, helping you  get the answer: (Copper Chloride)

Copper(II) chloride is the chemical compound with the chemical formula CuCl 2. This is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate.

Etching helps us to see the structure of the atoms of copper.

The term etching refers to the process by which we expose the inner structure of copper. It is usually done electrically or by the use of an acid. The surface of the copper is removed and the inner structure of the copper is shown.

As such, when you etch copper, you can see the inner structure such as the arrangement of the atoms of copper and how they fit together.

As such looking through the etched copper would help you to appreciate that matter is composed of atoms.
