What is the critical angle for the interface between water and fused quartz? nquartz= 1.46, nwater= 1.33.
The critical angle for the interface between water and fused quartz is 1.097.
What is the critical angle?It is the greatest angle at which the ray of light travelling in a transparent medium can strike the boundary
By the formula of critical angle
[tex]\theta _C = arcsin( \dfrac {n_2}{n_1} )[/tex]
Given, n quartz is 1.46 and n water is 1.33.
Putting the value in the equation
[tex]\theta _C = arcsin( \dfrac {1.46}{1.33} ) = 1.097[/tex]
Thus, the critical angle for the interface between water and fused quartz is 1.097.

What was the migration pattern of early humans?
Homo Sapien migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the early expansions of hominins out of Africa of Homo erectus. This initial migration was followed by other archaic humans.
Anthropologists have researched to find out that early humans used to move from one place to another due to climatic conditions. One theory suggests that early man lived in Africa and then moved out from the African continent in successive waves.

Which expression is equivalent to (2x + 9)² - (x-7)?
Answer:
[tex]\boxed{\bf B. \: 4 {x}^{2} + 35x+88}[/tex]
Explanation:
In order to find what expression is equivalent to (2x + 9)² - (x-7), we'll use the binomial theorem (a+b)^2 =a^2+2ab+b^2 to expand (2x+9).
[tex]\bf 4 {x}^{2} +36x+81 - (x - 7)[/tex]
[tex]\bf 4 {x}^{2} +36x+81 - x+7[/tex]
Let's combine like terms. 36x + (-x) = 35x
[tex]\bf 4 {x}^{2} + 35x+81+7[/tex]
Add numbers. 81 + 7 = 88
[tex]\bf 4 {x}^{2} + 35x+88[/tex]

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student studied for the test if they pass it with a b or higher? 0.20 0.55 0.60 0.80
The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.
How to calculate the probability?In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.
Let S represent studied for.Let B represent a score of B or higher gradeTherefore, we need to find P(S|B):
[tex]S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}[/tex]

what caused relations to deteriorate between the united states and the soviet union in 1979? the united states invaded afghanistan to prevent the spread of communism. the soviet union invaded afghanistan to help its communist government. the shah of iran entered the united states, which angered communists. the united states fought the taliban, which angered communists.
Answer:The Soviet Union invaded Afghanistan caused relations to deteriorate between the United States and the Soviet Union in 1979.
Explanation:
The Soviet Union, officially the Union of Soviet Socialist Republics, was a socialist and communist state that spanned much of Eurasia from 1922 to 1991. It was nominally a federal union of fifteen national republics; in practice its government and economy were highly centralized until its final years. The country was a one-party state governed by the Communist Party of the Soviet Union, with Moscow as its capital within its largest and most populous republic, the Russian SFSR. Other major urban centers were Leningrad, Kiev, Minsk, Tashkent, Alma-Ata and Novosibirsk. It was the largest country in the world, covering over 22,402,200 square kilometres, and spanning eleven time zones.
The Soviet Union invaded Afghanistan to help its communist government.
What is Soviet Union?The Soviet Union, officially known as the Union of Soviet Socialist Republics (USSR), was an Eastern European and northern Asian federal socialist state that existed from 1922 to 1991.
It was the world's largest country by land area, covering over 22 million square kilometres, and was made up of 15 republics.
The Soviet Union invaded Afghanistan in 1979 to support the communist government in power at the time.
The Soviet intervention was met with opposition from Afghan rebel forces known as the Mujahideen, who were backed by the US and other Western countries.
Thus, the conflict lasted more than a decade and ended with the withdrawal of Soviet forces in 1989, but the consequences for both Afghanistan and the Soviet Union were long-lasting.

Think about the benefits of each type of federal student loan and then discuss how you feel about taking out student loans to pay for college. Consider the options that you have for funding your education besides taking out loans.

Federal student loans generally have lower interest rates than private loans. Rates for new federal loans are also fixed, meaning they'll stay the same during your entire loan term. Private loans frequently offer variable rates, which increase whenever the Federal Reserve raises the interest rate benchmark.
Altitudes $\overline{ad}$ and $\overline{be}$ of acute triangle $abc$ intersect at point $h$. if $\angle ahb = 128^\circ$ and $\angle bah = 28^\circ$, then what is $\angle hca$ in degrees?
The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.
What other principles were used to arrive at the answer?
The other principles of mathematics that were used to arrive at the above answer are:
Total Angles on a straight line; Total Angles on a point; and Line segments.What are the Steps to the Solution?Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.
We also know that:
The sum of angles in a triangle is 180°;...................AThe sum of angles on a straight line is 180°;.........BThe sum of angles in a polygon is 360°; while.....CThe total sum of angles at a point is 360°.............DSince A...therefore:
When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.
By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.
Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.
To verify that our answer is correct, recall that sum of angles in a polygon is 360°
That means:
∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°
That is, 90+ 128 + 90 + 52 = 360°
