A copper calorimeter of negligible thermal capacity is filled with a liquid. The mass of the liquid is 250 gm. A heating element found that the temperature of the calorimeter and its contents rise form 25^(@)C to 30^(@)C in 5 minutes when a current of 2.05 A is passed through it at al potential difference of 5 volts. The liquid isthrown off and the heater is switched on again. it is now found that the temperature of the calorimeter alone remains constant at 32^(@)C when the current through the heater is 0.7 A at the potential difference 6 volts. Calculate the specific heat capacity of the liquid. The temperature of the surrounding is 25^(@)C

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 ?
