The speeds of sound in air and sea - water are given to be 340 m/s and 1440 m/s respectively. A ship sends a strong signal straight down and detects its echo after 1.5 sec. The depth of the sea at that point is? And can anybody tell me which book is this question from? please?

Answer»

Speed of SOUND in WATER = 1440m PER secondTime = 1.5sDistance = 2 x DEPTH. eq.1let depth be 'd'Speed = Distance/time1440 = Distance/1.51440 x 1.5 = Distance2160 m = DISTANCEDISTANCE = 2 x depth from eq.12160 = 2 x depthDepth = 2160/2Depth = 1080mHope it helps !Read more on Brainly.in - brainly.in/question/2386337#readmore
