The sonar of a stationary ship sends a signal with a frequency of hertz 6.66x103 down through water. The speed of the signal is 1.5x10 meters per second. The echo from the bottom is detected 5.3 seconds later. What is the depth of the water under the ship? (Round to the singles place, no decimal points or units.)​

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
