elongation (or cOmpresk P 6 (b) and (b) the time-period of vertical oscillations of the and block when it is slightly depressed and released. 25. A cube of ice of edge 4 cm is placed in an empty cylindrical glasS of inner diameter 6 cm. Assume that the ice melts uniformly from each side so that it always retains its cubical shape. Remembering that ice is lighter than water, find the length of the edge of the ice cube at the instant it just leaves contact with the bottom of the glass. 6.
