Which piece of evidence explains what is causing schools to receive extra food this fall? (A) Meatless Mondays and Taco Tuesdays are already on the menus for school lunches. Now some may get Trade Mitigation Thursdays. (B) It's buying the food to help farmers hurt by trade negotiations. This is called trade mitigation. (C) The USDA has long purchased and distributed agricultural products to help farmers, who can face swings in supply and demand in any given year. (D) Schools account for a majority of the $27 million of products ordered for child nutrition programs.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
