On the average a submarine on patrol sights 6 enemy ships per hour. Assuming the number of ships sighted in length of time is a Poisson variate the probability of sighting 6 ships in the next half an hour is

An indian submarine is moving in the Arabian sea with constant velocity. To detect enemy it sends out sonar waves which travel with velocity 1050(m)/(s) in water. Initially the waves are getting reflected from a fixed island and the reflected waves are coming back to submarine. The frequency of reflected waves are detected by the submarine and found to be 10% greater than the sent waves. Now an enemy ship comes in front, due to which the frequency of reflected waves detected by submarine becomes 21% greater than the sent waves. Q If the wavelength received by enemy ship is lamda' and wavelength of reflected waves received by submarine is lamda'' , then ((lamda')/(lamda'')) equals

After rising a short distance, the smooth column of smoke from a cigarette breaks up into an irregular and random pattern. In a similar fashion, a stream of fluid flowing past an obstacle breaks up into eddies and vortices which give the flow irregular velocity components transverse to the flow direction. Other examples include the wakes left in water by moving ships, the sound produced by whistling and by wind instruments. These examples are the results of
