Two friends A and B are standing a distance x apart in an open field and wind is blowing from A to B.A beats a drum and B hears the sound t_1 timed after he sees the event. A and B interchange their positions and the experiment is repeated. This time B hears the drum t_2 time after he sees the event. Suppose A and B in the previous problem change their positions in such a way that the line joining them becomes perpendicular to the direction of wind while maintaining the separation x. What will be the time lag B finds betweenseeing and hearing the drum beating by A?

Consider the situation of the previous problem. Assume that the temperature of the water at the botton of the lake remains contant at 4^(@)C as the ice forms on the surface (the heat required to maintain the temperature of the bottom layer may come from the bed of the lake).
