TASK DEFINITION: In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: 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.

SOLUTION: Science

PROBLEM: First proposed by Lewis, it is related logarithmically to a gas's standard Gibbs free energy divided by the temperature and gas constant. At equilibrium, this quantity must be equal in both gas and liquid phases. Taking the derivative of the natural log of this function is equates it to the derivative of a reaction's chemical potential. Equal to the gas' pressure when the gas is ideal, FTP, identify this thermodynamic quantity which replaces partial pressure when working with real gases and describes the tendency of a substance to escape from its current phase, symbolized by f.

SOLUTION: Science

PROBLEM: He adapted Joseph Blackburn's portrait d'apparat method for his works depicting a fat-looking woman with a blue book in Mrs. James Russell, Katherine Graves, an old elegant lady with a hint of a mustache in Mrs. Thomas Boylston, and a red-coated Samuel Adams. Influenced by John Smibert, his later historical works include The Death of the Earl of Chatham and The Death of Major Peirson. His The Boy with a Squirrel got him noticed, and he also painted a famous portrait of Paul Revere at his silver shop. FTP, name this American artist who depicted a dangerous incident occurring in Havana harbor in his Watson and the Shark.
