Consider a cloudless day on which the sun shines down across the United States. If 2513 kJ of energy reaches a square meter (m²) of the United States in one hour, how much total solar energy reaches the entire United States per hour? The entire area of
the United States is 9,158,960 km².

elements make up everything, and they combine to make compounds.

the answer is c

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
