P(1)(1 + i)
1 + 11) 121 - 1
M = (1 + )

it's all four options.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.
