A ship sends out ultrasound that returns from the seabed and is detected after 3.42 s. If the speed of ultrasound through sea water is 1531 `ms^(-1)` what is the distance of the seabed from the ship?

Text Solution

Verified by Experts

Time between transmission and detection t-3.42 s Speed of ultrasound in sea water, v = 1531 `ms^(-1)`
Distance travelled by the ultrasound =`2 xx"Depth of the sea"-
2d= Speed of sound X time
=1531 m `s^(-1)xx 3.42 s =5236 m`
d=5236 m/2 =2618
Thus ,the distance of the seabed from the ship is 2618 m or 2.62 km.

A stationary (steady) ship transmits ultrasonic sound, that returns from the seabed, after the transmission it is received after 4s. If velocity of the ultrasonic sound in the sea is 1531 ms^(-1) then what is the distance of the seabed from the ship?

Two blocks of mass m_(1)=10kg and m_(2)=5kg connected to each other by a massless inextensible string of length 0.3m are placed along a diameter of the turntable. The coefficient of friction between the table and m_(1) is 0.5 while there is no friction between m_(2) and the table. the table is rotating with an angular velocity of 10rad//s . about a vertical axis passing through its center O . the masses are placed along the diameter of the table on either side of the center O such that the mass m_(1) is at a distance of 0.124m from O . the masses are observed to be at a rest with respect to an observed on the tuntable (g=9.8m//s^(2)) . (a) Calculate the friction on m_(1) (b) What should be the minimum angular speed of the turntable so that the masses will slip from this position? (c ) How should the masses be placed with the string remaining taut so that there is no friction on m_(1) .

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of the water and the fly at the end of the string rests on the water 3.6 m away from her and 2.4 m from a point directly under the tip of the rod. Assuming that her string (from the tip of her rod to the fly) is taut, how much string does she have out (see the given figure)? If she pulls in the string at the rate of 5 cm per second, what will be the horizontal distance of the fly from her after 12 seconds?

A horizontal cylinderical tank (6)/(pi)m in diameter is half full of water. The space above the water is filled with a pressurized gas of unknown refractive index. A small laser can move along the curved bottom of the water and aims a light beam towards the centre of the water surface. When the laser has moved a distance s=1m or more (measured from curved face) from the lowest point in water, no light enters the gas. The refractive index of gas is (mu_("water") = 4//3)
