In the early days of automobiles, illumination at night was provided by burning acetylene, C 2 H 2 . Though no longer used as auto headlamps, acetylene is still used as a source of light by some cave explorers. The acetylene is (was) prepared in the lamp by the reaction of water with calcium carbide, CaC 2 :   \text{CaC}_{2}(s) + 2\text{H}_{2}\text{O}(l)\ \longrightarrow\ \text{Ca}\left( \text{OH} \right)_{2}(s) + \text{C}_{2}\text{H}_{2}(g).   Calculate the standard enthalpy of the reaction. The \text{Δ}H_{\text{f}}^{{^\circ}} of CaC 2 is −15.14 kcal/mol.

(a) A shirtless rider under a circus tent feels the heat radiating from the sunlit portion of the tent. Calculate the temperature of the tent canvas based on the following information: The shirtless rider’s skin temperature is \text{34}\text{.}\text{0ºC} and has an emissivity of 0.Њ. The exposed area of skin is 0\text{.}\text{400}\ \text{~m}^{2} . He receives radiation at the rate of 20.0 W—half what you would calculate if the entire region behind him was hot. The rest of the surroundings are at \text{34}\text{.}\text{0ºC} . (b) Discuss how this situation would change if the sunlit side of the tent was nearly pure white and if the rider was covered by a white tunic.

Consider the velocity vs. time graph of a person in an elevator shown inFigure 2.56. Suppose the elevator is initially at rest. It then accelerates for 3 seconds, maintains that velocity for 15 seconds, then decelerates for 5 seconds until it stops. The acceleration for the entire trip is not constant so we cannot use the equations of motion fromMotion Equations for Constant Acceleration in One Dimensionfor the complete trip. (We could, however, use them in the three individual sections where acceleration is a constant.) Sketch graphs of (a) position vs. time and (b) acceleration vs. time for this trip. Figure2.56

Which assessment of Herbert Hooverâs presidency is most accurate? Hooverâs policies caused the stock market crash and subsequent depression.Although he did not cause the stock market crash, Hoover deserves criticism for his inadequate response to it.Hoover pledged a great deal of direct federal aid to unemployed Americans, overtaxing the federal budget and worsening the financial crisis.Hoover disapproved of American capitalism and therefore attempted to forestall any concrete solutions to the Depression.
