Are diamonds shiny or dull?

Also can you give me an example of dull?

Answers

Answer 1
Answer: Diamonds are shiny. Dull is low in luster,
Answer 2
Answer: Diamonds are shiny.  An example of something that is dull would be a metal that does not have a shiny value to it (reflects light very well).  One example would be concrete.

Law of action-reaction

Answers

Answer:

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

discuss the relationship between the size and weight of an object and the amount of friction that is present

Answers

As both size and weight of an object increase, so will the amount of friction. The bigger size an object is, the more surface area it will have, and the heavier an object is, the more pressure it will place on something else. Both these factors lead to increased friction.

Which organic molecule is digested into simple sugar?

Answers

Whilst inorganic molecules, such as the mineral calcium, are broken down into smaller molecules, they aren't broken down into simpler structures, because they are already in their simplest form. 

Large organic molecules such as starch need to be broken down into simpler forms - maltose and glucose respectively via digestion. Other organic larger molecules are broken down into simpler forms like protein to amino acids and lipids to fatty acids and glycerol etc. 

Glucose is one of several simple sugars (monosaccharides). 

Biological catalysts are what help to break down these large molecules (polymers) to simpler ones (monomers), they are called enzymes.

What are three ways that magma can form

Answers

The three ways of magma formation are, decompression melting brought on by reducing pressure, 2) Flux melting brought on by introducing volatiles  and 3) Heat-induced melting brought on by raising temperature.

What is magma?

Magma is the molten fluid in the earth crest which eventually forms the rocks.Here are the three main ways that rock behavior can move past the green solidus line and result in molten magma:

1) Decompression melting brought on by reducing pressure, 2) Flux melting brought on by introducing volatiles and 3) Heat-induced melting brought on by raising temperature.

Different temperatures cause minerals to melt, as demonstrated by the Bowen's reaction Series. The solidus border is more of a fuzzy zone than a clearly defined line since magma is a mixture of many minerals; some minerals melt while others remain solid.

Partially melting rocks have the same characteristics as real-world magmas, which often include solid, liquid, and volatile components.

#SPJ2
The three ways magma can form are when rock is heated, when pressure is released, and when the composition of the rock changes. The temperature of magma is 1300-2400F. Magma collects in magma chambers under the earth's surface, and can be come to the surface in the form of lava.
