AND CORRECT ANSWERS
Sound waves, - CORRECT ANSWER An analogy that compares these phenomena to electrical
signals defines their impedance as the ratio of pressure to flow rate. Hermann von Helmholtz names a
kind of cavity that amplifies these phenomena at a particular frequency. A parameter governing these
phenomena marks the onset of choked flow in compressible fluids. These phenomena travel at a (*)
speed proportional to the square root of air pressure over air density, which works out to about 343
meters per second in room-temperature air. Objects moving faster than these phenomena have a Mach
number greater than 1. For 10 points, name these longitudinal waves whose intensity is measured in
decibels.
The Amazons - CORRECT ANSWER According to Book 11 of the Aeneid, this group may
include a member of the Volsci named Camilla; at various other times, the leader of this group is
named as Myrina. During the nightmarish last days of the Trojan War, a leader of this group is killed
by Achilles, who weeps over the corpse. During a great battle against Heracles and Theseus, many of
their members are killed, including, according to some sources, (*) Pen·the·silea [pen-theh-zih-LAY-
uh]. For his ninth labour, Heracles retrieves the belt of one of these people named Hippolyta. These
people are said to cut off their right breasts to shoot arrows better. For 10 points, name this tribe of
warrior women in Greek mythology.
Arthur Miller - CORRECT ANSWER One of this man's characters thinks that her son must be
alive because November 25th was his "favorable day." In that play by this man, children play the
game "jail" in a front yard where Frank Lubey tries to use horoscopes to find a missing soldier. In a
play by this man, Ann Deever gets engaged to Chris Keller, whose reading of his brother Larry's
suicide note forces their father to admit to having sold faulty (*) airplane parts that killed 21 pilots.
Another of his plays ends with the title man's funeral after he crashes his car for the life insurance
money. Happy and Biff are the sons of Willy Loman in that play by this author of All My Sons. For 10
points, who wrote Death of a Salesman?
Czech - CORRECT ANSWER A novel in this language analyzes itself using the musical
notion of a "motif" and illustrates the notion that "What happens but once, might as well not have
happened at all." In that novel in this language, a professor dies in Cambodia trying to join the "Grand
March of History," and a painter shows her originality by wearing a (*) bowler hat. This language was
used for a play in which Helena fights for the rights of Dr. Gall's title automatons. A novel in this
language depicts the lives of Tereza and Tomas during a 1968 revolution. For 10 points name this
Eastern European language used by Karel Čapek in R.U.R. and Milan Kundera in The Unbearable
Lightness of Being.
Viola Davis - CORRECT ANSWER In an early role, this actress says "why you gotta know
something like that for sure when you don't," in a monologue where she repeats "it's just till June."
,Despite having only one scene, she was nominated for Best Supporting Actress for playing Donald's
mother in Doubt. In a 2011 film, her character works for the "Godless woman" Elizabeth and helps
Skeeter write about her fellow (*) maid, Minny. In a 2016 film, this actress gained attention for "snot-
crying" as Rose Maxson, the wife of the garbageman Troy. For 10 points, name this black actress who
played Aibileen in The Help, stars in How to Get Away With Murder, and starred opposite Denzel
Washington in Fences.
Markov - CORRECT ANSWER This mathematician proved that the probability of "a random
variable being greater than or equal to a" is less than or equal to "its expected value divided by a." The
simplest dynamic Bayesian network is a "hidden" example of this mathematician's namesake model.
Chebyshev's inequality can be proven using this man's namesake inequality. He names a model in
which the current (*) state is multiplied by a transition matrix to find probabilities of the next state.
Random walks and other stochastic processes can be studied using—for 10 points—what Russian
mathematician's namesake "chains"?
"Pathetique" - CORRECT ANSWER A C-minor piece with this nickname has an A-flat major
second movement marked "Adagio cantabile," whose theme begins "C, B-flat, E-flat." This is the
nickname of a C-minor piece whose first movement alternates between an "Allegro con brio" and a
"Grave" introduction in dotted rhythms. A symphony with this nickname was the first to include a
dynamic marking of six Ps, and has a (*) 5-4-time "limping" waltz for a second movement. That B-
minor symphony with this nickname premiered just days before its Russian composer died of possibly
self-inflicted cholera. For 10 points, give this nickname of Beethoven's eighth piano sonata and
Tchaikovsky's sixth symphony.
John Coltrane - CORRECT ANSWER One of this man's songs begins with the major chords
"B D, G B-flat, E-flat" in three quick bars. This man punningly remade Miles Davis's "Tune Up" into
another song with a major-third-based progression. He worked with Eric Dolphy on albums for
Impulse Records like Africa/Brass. Pianist McCoy Tyner played on an album by him consisting of the
tracks (*) "Pursuance," "Restitution," "Psalm," and "Acknowledgement." He played sax next to
Cannonball Adderley on Kind of Blue, and included tracks like "Countdown" and "Naima" on an
album made seven years before his 1967 death. For 10 points, name this saxophonist behind Giant
Steps and A Love Supreme.
Oxidation states - CORRECT ANSWER This value is plotted against free energy on Frost
diagrams. This value changes at two carbons in ozonolysis. An increase in this value increases a
bond's covalent character. This value is unusually high for the central atom of permanganate. When
calculating this value, electrons are assigned to the more electronegative atom, unlike in (*) formal
charge computations. This value decreases for an atom undergoing a reduction. This value, which
determines the suffixes "-ous" and "-ic," is written with Roman numerals in parentheses. For 10
points, name this value, the number of electrons an atom has gained or lost.
, Republic of Madagascar - CORRECT ANSWER Periwinkle species native to this country have
been used to treat illnesses including Hodgkin's disease and leukemia. This country is home to a
carnivorous animal similar to cats and mongooses, called the fossa. The traveler's palm is featured on
the national emblem of this home to the 19th-century Canal des (*) Pangalanes. Most species of
baobab trees are native to this country. Along with Indonesia, this country is the world's largest
producer of cloves and vanilla. Mayotte lies southeast to this home of the Merina ethnic group, who
speak Malagasy. Lemurs are found on—for 10 points—what large island country that the
Mozambique channel separates from southeast Africa?

Power - CORRECT ANSWER For an ideal dipole antenna, dividing this quantity by current-
squared gives the radiation resistance. For an electromagnetic wave, the amount of this quantity per
unit area is given by the Poynting vector, and in general its amount per unit area is given by intensity.
For a purely resistive load, this quantity's RMS value is exactly half its peak value. For a resistor, this
quantity is equal to "I (*) squared times R" according to Joule's heating law. This quantity equals
current times voltage for electrical systems. In general, it is the time derivative of work. The amount
of energy consumed per unit time is—for 10 points—what quantity measured in watts?
Paper - CORRECT ANSWER This material's "tooth" varies in its "cold press" and "hot press"
types, and it can sometimes feature a laid pattern. The "rag" type of this material is often heavily
deckled. Types of this material are often differentiated by their "caliper" and "basis weight," measured
in pounds. Artworks made from this material can start with (*) bases like "kite" or "waterbomb."
Manufacturers of this material are identified by their watermarks. 3D objects are often made of this
material by layering strips of it soaked in a flour-water mixture. Sizes like A1 describe—for 10
points—what material that's folded to make origami?
Art songs - CORRECT ANSWER Description acceptable. A D-minor piece in this genre uses a
"circling" right-hand figure and a "thumping" left-hand figure to depict both the title object and the
title girl's heart. Another piece in this genre uses different registers to represent three characters and
uses pounding octave Gs in the right hand to depict a galloping horse. A set of these works begins "A
stranger I arrived..." or "Fremd bin ich eingezogen" [fremt BIN eekh eyen-gu-TZOH-gen] in the piece
(*) "Gute Nacht" [GOO-tuh nakht]. "Gretchen am Spinnrade [SHPIN-rah-duh]" and "Erlkönig"
[EHRL-kur-nikh] are among Franz Schubert's over 600 works in this genre, including Winterreise, a
