How do S and P waves move through a solid material?
abruzzese [7]

P waves move quickly and S waves move slowly through solids,

Explanation:

S and P waves can move through a solid material. P waves generally moves quickly and S-waves move slowly through solids.

S and P waves elastic seismic waves.

  • P waves are primary waves travels through any material medium. They move faster than S-waves.
  • S waves are secondary waves that moves through solid only. They are shear waves.
  • They cannot move through liquids and gases because these materials cannot be sheared.

At a seismic station, P waves arrives first because they have a higher velocity

How does nickel make stainless steel not magnetic?.
9966 [12]
The nickel, itself ferromagnetic, reduces the magnetism in stainless steel but not to zero. Austenitic stainless steel is defined as the steel crystal structure that is face centered cubic which is the same structure hot iron has as one of the allotropes of iron. Nickel above a certain percentage (18) stabilizes austenite structure just as if you took carbon steel and heated it above 730–770 C. Above this temperature the structure is FCC and above the Currie temperature where magnetism is killed due to the isotopic symmetry of the structure. However, you can still get a small magnetic attraction from austenitic stainless steel if it is cold worked, heat treated a certain way or welded. So it is not a guarantee that austenitic stainless is totally non magnetic.

Addition of a catalyst can speed up a reaction by providing an alternate reaction pathway that has a
kkurt [141]

Answer:

Addition of a catalyst can speed up a reaction by providing an alternate reaction pathway that has a lower activation energy

Explanation:

A catalyst is an agent that increases the rate of a chemical reaction by providing an alternate pathway for the reaction that requires a lower activation energy. As the requirement for activation energy is less in the presence of a catalyst, there are more reactant particles becoming involved in the chemical reaction and as such there are more products formed per unit time, or there is an increase in the rate of the reaction

Example of catalyst include

1. Addition of potassium permanganate to hydrogen peroxide to aid in the rapid decomposition into water and oxygen

2. Platinum serves as a catalyst in the complete combustion of carbon monoxide into carbon dioxide.
