Crustal deformation builds landforms when two tectonic plates start to push into each other they can rise up and build mountains, or when they sink under, they create valleys.
How crustal deformation builds landforms?Tectonic pressure in a crust can cause folding. Folding can end up with the formation of valleys and mountains so we can conclude that when two tectonic plates start to push into each other they can rise up and build mountains, or when they sink under, they create deep valleys.

explain newtons 2nd law of motion by using the example of a rollercoaster
Answer:
When the cart gets to down-hill drop, for a moment it is at rest, until gravity (a force) acts upon the cart and causes it to accelerate downward.
Explanation:
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

What is the double-stranded nucleic acid?
Answer:
Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.

what is endothermic reaction
Answer:
Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
Answer:
Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.

A reaction vessel at 1215k contains a mixture of SO2( P = 2. 98 bar) and O2(P = 1. 18 bar). When a catalyst is added, this reaction takes place: 2SO2(g)+O2(g)⇌2SO3(g) At equilibrium the total pressure is 3. 80 bar.
Find the value of k?
This problem is providing the equilibrium reaction whereby SO3 is produced and asks for the value of the equilibrium constant. After the calculations, the answer turns out to be 0.124.
Chemical equilibrium.In chemistry, when a chemical reaction attempts to go to completion, it might experience a limitation known as equilibrium; a condition where it is not able to proceed any further.
In such a way, for the given reaction:
[tex]2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)[/tex]
We can write the equilibrium expression as:
[tex]K=\frac{p_{SO_3}^2}{p_{SO_2}^2p_{O_2}}[/tex]
Hence, given the total pressure at equilibrium, we can add the pressures of all the species at equilibrium including the reaction extent, x:
[tex]P_{eq}=p_{SO_3}+p_{SO_2}+p_{O_2}\\\\3.80=(2x)+(2.98-2x)+(1.18-x)[/tex]
Thus, we solve for x to obtain:
[tex]3.80-2.98-1.18=2x-2x-x\\\\-0.36=-x\\\\x=0.36bar[/tex]
Hence, we plug it in into the equilibrium expression to obtain the equilibrium constant as follows:
[tex]K=\frac{(2x)^2}{(2.98-2x)^2(1.18-x)}\\\\K=\frac{(2*0.36)^2}{(2.98-2*0.36)^2(1.18-0.36)}\\\\K=0.124[/tex]

When copper metal is added to silver nitrate
in solution, silver metal and copper(II) nitrate
are produced. What mass of silver is produced
from 52 g of Cu?
Answer in units of g.
Step 1: Write the chemical equation:
2Cu + AgNO₃ → Cu(NO₃)₂ + Ag
Step 2: Calculate the moles of Cu:
n(Cu) = mass/Ar
n(Cu) = 52 / 63.546
n(Cu)= 0.818 mol
Step 3: Find the mole ratio between Cu an Ag and figure out the moles of Ag
Cu : Ag
2 : 1
0.818 : 0.818 / 2
0.818 : 0.409
Thus, n(Ag) = 0.409 mol
Step 4: Find the mass of Ag:
Mass of Ag = moles × Ar.
Mass = 0.409 × 107.8682
Mass = 44.11g

Waste dairy whey is used to grow Kluyveromyces fragilis yeast in a continuous culture system operated at 30C and 1 atm pressure. Medium containing 4% w/w lactose (C12H22O11) and 0. 15% w/w NH3 flows into a specially designed aerated bioreactor at a rate of 200 kg h21. The reactor is compartmentalised to facilitate gravity settling of the yeast; a suspension containing concentrated cells is drawn off continuously from the bottom of the reactor at a rate of 40 kg h21, while an aqueous waste stream containing 0. 5 kg cells per 100 kg leaves from the top. All of the lactose provided is utilised by the culture. The biomass yield from lactose is known from preliminary experiments to be 0. 25 g g21. The composition of the K.

Write a paragraph (5-7 sentences) describing pH and conductivity.
Answer:
pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H3O+ equals the concentration of OH− in pure water. On the other hand, electrical conductivity is a non-specific measurement of the concentration of both positively and negatively charged ions within a sample. So the short answer to the question is as follows, the presence of any hydrogen ions present in a substance will impact the pH level and most probably influence conductivity levels. However, hydrogen ions make up only a small part of the ion concentration measured by a conductivity meter.
