    A 5 m long cylindrical steel wire with radius 2xx10 ^(-3) m is suspended vertically from a rigid support and carries a bob of mass 100 kg at the other end . If the bob gets snapped , calculate the change in temperature of the wire ignoring radiation losses. ( Take g = 10 m//s ^(2) ) ( For the steel wire , young's modulus = 2.1 xx10^(11) N//m^(2) , Density = 7860 kg// m^(3) , Specific heat = 420 J// kg ^@ C ) .

    The figure represents the instantaneous picture of a transverse wave travelling along the negative x-axis. Choose the correct alternative (s) related to the movement of the 9 points shown in the figure. (Instantaneous velocity) A perfectly elastic uniform string is suspended vertically with its upper end fixed to the ceiling and the lower end loaded with the weight. If a transverse wave is imparted to the lower end of the string, the pulse will

    A body of mass m is attached to one end of a massless spring which is suspended vertically from a fixed point. The mass is held in hand, so that the spring is neighter stretched nor comprssed. Suddenly the support of the hand is removed. The lawest position attained by the mass during oscillation is 4 cm below the point, where it was held in hand.
