Several centimeters of lead. Gamma rays have the highest penetrating power and therefore need a thick layer of something, in most cases lead, to prevent penetration. (This is why if you have ever go to the dentist they put a heavy thing on you made of lead, to prevent the penetration of gamma rays that can destroy your most important organs).

Luis is helping his parents paint a border around the walls of a room. He uses a stencil to repeat the same design on each wall
iren [92.7K]

Answer:

Polymerization.

Explanation:

Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.

Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.

In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.

Polymerization is given by the chemical formula;

nA -----> A(n).

In this scenario, Luis uses a stencil to repeat the same design on each wall to form one long grapevine with a bunch of grapes every foot along its length.

Hence, the type of chemical reaction this best model is polymerization because it involved repeating the same design (monomers) to form a long grapevine with a bunch of grapes (polymers).

Elias could be standing on the transform boundary.

Answer: Option 1.

<u>Explanation:</u>

Transform boundaries are places where plates slide sideways past one another. At change limits lithosphere is neither made nor devastated. Many change limits are found on the ocean bottom, where they associate fragments of veering mid-sea edges. California's San Andreas issue is a transform boundary.

Transform boundaries are regions where the Earth's plates move past one another, scouring along the edges. Every one of these three sorts of plate limit has its own specific kind of flaw (or break) along which movement happens. Transforms are strike-slip issues. There is no vertical movement—just horizontal.
