Q: This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.

Q: One novel set in this city features "apparat"s that share data about characters like Eunice Park and Lenny Abramov. That novel is Gary Shtyenngart's Super Sad True Love Story. In another novel set here a key found in an envelope prompts a meeting at which William Black is told by Oskar Schell about a voicemail consisting of the repeated phrase "Are you there" In another novel set here Keith Neudecker's estranged wife Lianne repeatedly sees the title street performer. For 10 points, name this setting of Jonathan Safran Foer's Extremely Loud and Incredibly Close and Don DeLillo's Falling Man, both of which center on responses to the 9/11 attacks.

Q: The reaction of this molecule with oxalyl chloride was the subject of pioneering photochemical work by Kharasch and Brown. Hassel's study of this molecule yielded its molecular structure and his 1943 paper "On The Conformations" of it elucidated those for the first time. Reacting it with pure oxygen forms adipic acid, which is used in the production of nylon. Its strain energy-bond angle curve has minima at twenty-three kilojoules per mole and maxima at forty-five kilojoules per mole, the former corresponding to the skew configuration, but its stable configuration is non-planar with a bond angle of about one hundred nine point five degrees. FTP, name this molecule having conformations twist, boat, and chair; a cyclic alkane with formula C6H12.
