The well known mineral fluorite is chemically calcium fluoride. It is known that in one unit cell of this mineral there are 4 Ca^(2+) ions and 8F^(-) ions and that Ca^(2+) ions are arranged in a fcc-lattice. The F^(-) ions fill all the tetrahedral holes in the face centred cubic lattice of Ca^(2+) ions. The edge of the unit cell is 5.46 xx 10^(-8) cm in length. The density of the solid is 3.18 g cm^(-3) . Use this information to calculate Avogadro's number. (Molar mass of CaF_(2) = 78.08 g mol^(-1) )

Let two non-collinear unit vectors hata and hatb form an acute angle. A point P moves so that at any time t the position vector vec(OP) (where O is the origin) is given by hata cos t + hatb sin t. When P is farthest from origin I, let M be the length of vec(OP) and hatu be teh unit vector along vec(OP). Then P:
