Copper has an weight of 63.55 g/mole and avogadro's number (6.02 x 10 atom/mol). then find: a) lattice constant for the unit cell (a)? b) radius of copper atom (r)? c) calculate the interatomic distance (d) of the (222) plane in the copper unit cell?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
