question:
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.

Science

question:
One protagonist in this novel spends a summer with the wife of Colonel Forster, and that character's aunt and uncle have the surname Gardiner. One character in this novel initially rejects a marriage proposal by Mr. Collins, while her sister is romanced by Mr. Bingley, and another romance in this novel is initiated by the master of Pemberley, Mr. Darcy.

answer:
Literature

question:
A mixture of this compound and hydrogen peroxide is used in the Piranha clean. This compound is produced along with hydrogen iodide in the Bunsen reaction, part of a cycle used to produce hydrogen gas. This compound is reacted with sodium chloride in the Mannheim process and is useful in the production of fertilizer because it is added to apatite in the "wet method" of phosphoric acid production. This compound can reversibly add a blocking group to benzene rings and protonates nitric acid for electrophilic aromatic substitution. A vanadium-five oxide catalyst is used for the production of this compound in the contact process. For 10 points, name this diprotic acid with formula H2SO4.
