1.	Assertion : Heating enegineersuse u-values , rather than k-valueswhen calculatingheatlosses through walls, windows and roots . Reason : The u-values of a singlebrick wallis1.7Wm^(-2)K^(-1)
Answer» If both the assertion and reason are true statement ANDREASON is correct explanation of the assertion . If both the assertion and reason are true statement but reason is not a correct explanation of the assertion . If the assertion is true but the reason is a false statement. If both assertion and reason are false statements. Solution :The u-value of a single BRICK wall is 3.6 ` W m^(-2)K^(-1)`

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 ?
