To calculate:The frequency of sound perceived by a submarine from another submarine.
Answer to Problem 4PP
The frequency of sound perceived by thedetector submarine from another submarine is
Explanation of Solution
Given information:
Speed of sound in water (
Velocity of first submarine (source) (
Velocity of second submarine (detector) (
Frequency of wave (
The first submarine (source) is moving towards the detector submarine which is at rest.
Formula used:
Doppler Effect equation:
Where
Calculations:
As per problem,
To calculate frequency perceived by detector,
Substitute the values:
Conclusion:
Thus, the frequency perceived by the detector submarine is

- air is pushed steadily though a forced air pipe at a steady speed of 4.0 m/s. the pipe measures 56 cm by 22 cm. how fast will air move though a narrower portion of the pipe that is also rectangular and measures 32 cm by 22 cmarrow_forwardNo chatgpt pls will upvotearrow_forward13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
