An oxygen molecule consists of two oxygen nuclei, each of mass m = 2.7 × 10−26 kg, separated by a distance 1.2 × 10−10 m, and surrounded by a cloud of electrons, each of mass 9.1 × 10−31 kg. (a) ignoring the small mass of the electron, what is the moment of inertia for rotation of the nuclei around their center of mass? if this rotation has angular momentum equal to ~ , that is, planck’s constant divided by 2π, what is the corresponding energy of rotation? express your answer in units of electron volts (ev), where 1 ev = 1.6 × 10−19 j.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
