A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)
A) The surface area is increasing at the rate of 28pi square mm per second.
B) The surface area is decreasing at the rate of 28pi square mm per second.
C) The surface area is increasing at the rate if 32pi square mm per second.
D) The surface area is decreasing at the rate of 32pi square mm per second.
Answer:
Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
Explanation:
Given the data in the question;
let r be the radius and h be the height of the tube
so volume V = πr²h
dv/dt = πr² dh/dt + 2nrh dr/dt
⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt
⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2
Area Surface S = 2nrh
ds/dt = 2π ( r.dh/dt + h.dr/dt )
= 2π ( 6×2 + 2)
= 2π (14)
= 28π
therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )

Which one of the following equations correctly represents the process involved in the electron affinity of x?.
Electron affinity is known simply as the energy change from the addition of 1 e– to a gaseous element/ion. The one of the equations correctly represents the process involved in the electron affinity of x is X(g) + e- → X-(g)
For electron affinity,
Atom(g) + e– → Ion–(g), ΔE = –E.A.Electron affinity is simply known as the amount of energy that is given off when an electron is added to a neutral atom to create a negatively charged ion.
It is often hard to measure and as such the values are available for only a few chemical elements.

Researchers are investigating the effect of ph level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low ph , medium ph , or high ph , to the water in the tanks that hold the jellyfish.
In this experiment randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
In an experiment, variables are carefully controlled in order to ensure the reliability of the results. Usually, treatments are assigned randomly to experimental units. Randomization refers to the assignment of experimental units to groups by chance.
Randomization is important in this experiment because it tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
Missing parts;
Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?
A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
B. Randomization will make up for improper experimental design, data collection, and analysis.
C. Randomization makes the analysis easier since the data can be entered into the computer in any order.

The group that is made up of organisms that are all members of the same kingdom is fern, rose bush, and corn plant. The correct option is D.
What is taxonomic rank?Taxonomic rank is the relative level of a group of organisms in an ancestral or hereditary hierarchy in biological classification.
A common system consists of the following elements: species, genus, family, order, class, phylum, kingdom, and domain. Cladistics is another term for the study of taxonomy.
When it comes to taxonomic rank, the kingdom is the second highest, with smaller groups known as phyla.
Plantae is divided into four evolutionary related groups: bryophytes (mosses), seedless vascular plants, gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).
Kingdom Plantae consists of autotrophic, multicellular, photosynthetic eukaryotes. These are mostly non-motile, embryo-forming organisms that serve primarily as producers in the ecosystem by converting solar energy into chemical energy via photosynthesis.
Thus, the correct option is D.

The American Civil War, commonly referred to by other names, lasted from April 12, 1861, until May 26, 1865. The Union[f] ("the North") and the Confederacy ("the South"), the latter of which was made up of seceding states, engaged in combat.
The conflict over whether to allow slavery to spread into the western regions, creating more slave states, or to forbid it from doing so, which was widely believed to put slavery on the path to eventual extinction, was the main driver of the war.

You are going to write an essay about the life of a person whom you admire. Which two organizational aids could you use, and why?.
Answer:
Organizational aids are tools that allow an author to help the reader understand and follow the flow of information and ideas within a text. They provide a framework for organizing and connecting what has been written into a cohesive whole.
Explanation:
Two organizational aids that could be used to write about the life of someone whom you admire would either be chronological order or cause-and-effect. The chronological order might be used because the author may want to inform the reader about key events within the person's life, and this organizational aid would help to accomplish that goal. Using cause-and-effect could also work well because it could show how certain events were caused by other events, which ultimately led to the outcome of certain moments in the person's life.
Answer:
You can use a sequence chart or a timeline. Both organizational aids allow you to present the events of the person's life in order of occurrence.

A small fair charges an admission fee for children and adults. The cost for admission is $3 per adult and $2 per child. On a certain day, total admission fees were $900, and 350 people attended the fair. How many children attended the fair that day? 80 children 150 children 200 children 320 children.
150 children attended the fair for that day if $900, and 350 people attended the fair, hence option b is correct.
What is the number of children attended the fair?Detailed explanation:
Let's say there are x youngsters and y grownups.
350 persons in all visited the fair, thus.
So, x + y = 350.
In addition, fees per kid are $2 and fees per adult are $3.
Since, $900 is assumed to represent the entire sales.
So, 2x + 3y = 900
Consequently, we have the equation system,
2x + 3y = 900
x + y = 350
Now let's resolve the equations.
x + y = 350 ⇒ y = 350 - x
The result is that 2x + 3y = 900 2x + 3(350 -x) = 900 2x + 1050 - 3x = 900 -x = -150 x = 150.
The result is that y = 350 - x y = 350 - 150 y = 200.
Therefore, As a result, 150 children and 200 adults, respectively, visited the fair.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? The first law describes how thermal energy is conserved but not the direction it moves. The first law describes the direction thermal energy moves but not how it is conserved. The first law describes how thermal energy can be created but not how it can be destroyed. The first law describes how thermal energy can be destroyed but not how it can be created.
The statement which best describes the difference between the first law of thermodynamics in comparison with the second law of thermodynamics is that: A. The first law describes how thermal energy is conserved but not the direction it moves.
The First Law of Thermodynamics states that energy can neither be created nor destroyed but it can only be transformed (converted) from one form to another such as potential energy to kinetic energy. Thus, thermal energy is always conserved according to the First Law of Thermodynamics.
On the other hand, the Second Law of Thermodynamics states that the entropy (disorderliness) of an isolated system always increases and can never be decreased. Thus, the direction of an energy is described by the Second Law of Thermodynamics.
In conclusion, the difference between the First Law of Thermodynamics in comparison with the Second Law of Thermodynamics is that the first law describes how thermal energy is conserved but not the direction in which thermal energy moves.
