1.	A person makes a quantity of iced tea by mixing 250g of hot tea (essentially wwater ) with an equal mass of ice at its melting point.Assume the mixture has negligible energy exchange with its environment. If the tea's initial temperature is T_(i) = 90^(@)C, when thermal equilibrium is reached what are (a) the mixture's temperature T_(f) and (b) the remaining mass m_(f ) of ice ? If T_(i) = 70^(@)C, when thermal equilibriumis reached what are (c ) T_(f) and (d) m_(f ) ?
Answer» Answer :(a)`5.3^(@)C`; (B) 0; (c ) 0.220 kg = 220 g

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
