how to derrive doppler effect formula for when the observer is passing a stationery source to get the speed of the observer on its own on one side of the equal sign

SOLVE STEP BY STEP IN DIGITAL FORMAT DOPPLER EFFECT 13. A source emits a sound with a frequency equal to 261.63 Hz. It is necessary for an observer to hear a tone (apparent frequency) of 370 Hz. Calculate: a) How fast will the source have to move towards the observer? b) If the source remains at rest, with what speed will the observer have to move towards the source?

A UFO travels at such a speed as to remain above one point on the earth ata height of 200 km above the earth's surface. A radio signal of frequency 110:0 MHz is sent to the UFO. i.What is the shift in the frequency received by the UFO? ii. If the signal was reflected back to earth, what would be the observed frequency of the return signal?

A snake crawls from a hole to find food. It starts at 8 m SW; then goes 10 m 40o N of W; then sensed something moving 9 mS from where it is and moves to it.b. How far and in what direction was the moving object from the hole?c. If after realizing that the moving object was not good for food, the snake moved from itbecause it saw another moving thing, moved to its direction by covering a fourth unknowndisplacement and is now 20 m and 30o E of S from the hole. Determine the magnitude anddirection of the fourth displacement?

Two cars A & B are driving away from each other and sounding their horns. You are the driver of car B which is travelling at a speed of 23.6m/s and you measured the horn of the other car to be sounded at 885HZ, which is travelling at a speed of 27.9m/s. Speed of sound is 340m/s. Calculate the following: a) Speed of the observer in m/s %3D (0.5 mark) b) Speed of the source in m/s %3D (0.5 mark) c) frequency of the source (original) in hertz (1.5 mark) d) How much does the frequency of the source decreased (A) in hertz =

9. As the spaceship in Number 8 passes by the space dock, the ship's captain flashes a flashlight at 1.00 s interval as measured by space-dock personnel. How often does the flashlight flash relative to the captain? A. Every 0.87 s B. Every 1.15 s C. Every 1.00 s D. cannot determine

Check Your Understanding a. A particle travels at 1.90108m/sand lives 2.10108swhen at rest relative to an observer. How long does the particle live as viewed in the laboratory? b. Space craft A and B pass in opposite directions at a relative speed of 4.00107m/s . An internal clock in space craft A causes it to emit a radio signal for 1.00 s. The computer in spacecraft B corrects for the beginning and end of the signal having traveled different distances, to calculate the time interval during which ship A was emitting the signal. What is the time interval that the computer in spacecraft B calculates?

(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

A spacecraft zooms past the Earth with a constant velocity. An observer on the Earth measures that an undamaged clock on the spacecraft is ticking at one-third the rate of an identical clock on the Earth. What does an observer on the spacecraft measure about the Earth-based clock's ticking rate? (a) It runs more than three times faster than his own clock. (b) It runs three times faster than his own. (c) It runs at the same rate as his own. (d) It runs at one-third the rate of his own. (e) It runs at less than one-third the rate of his own.

(a) All but the closest galaxies are receding from our own Milky Way Galaxy. If a galaxy 12.0109ly ly away is receding from us at 0. 0.900c, at what velocity relative to us must we send an exploratory probe to approach the other galaxy at 0.990c, as measured from that galaxy? (b) How long will it take the probe to reach the other galaxy as measured from the Earth? You may assume that the velocity of the other galaxy remains constant. (c) How long will it then take for a radio signal to be beamed back? (All of this is possible in principle, but not practical.)
