There are two hills A and B and a car is travelling towards hill A along the line joining the two hills. Car is travelling at a constant speed u. There is a wind blowing at speed u in the direction of motion of the car (i.e., from hill B to A). When the car is at a distance x_(1) from A and x_(2) from B it sounds horn (for very short interval). Driver hears the echo of horn from both the hills at the same time. Find the ratio (x_(1))/(x_(2)) taking speed of sound in still air to ve V.

A short bar magnet moment 5.25 xx 10^(-2)JT^(-1) is placed with its axis perpendicular to the earth's field direction . At what distance from the centre of the magnet, the resultant field in inclind at 45^(@) with earth's field on (a) its normal bisector and (b) its axis . Magntiude of the earth's field at the place is given to be 0.42 G . Ignore the lenght of the magnet in comparison of the distance involved .
