frequency?
As two notes are sounded, 6 beats per second are heard. The frequency of one note is 571 Hz. What are the two possible frequencies of the other note?
sum and difference: 571 ± 6 = 565 and 577. Either of those will produce a "beat frequency" of 6 Hz when combined (mixed, or heterodyned) with 571 Hz.
How does frequency or angularvelocity begin to increase orcome to an end?
When frequency or angular velocity does not change frequency is an integer or a number (angle l/r). But no number is frequency or angular velocity when frequency increases or decreases. When rate of counting increases or frequency increases from 0 at uniform speed, within the first cycle, period per cycle decreases from infinity. Should there be a period within the first cycle (or 0 to 1). When frequency decreases at uniform speed, can we pronounce 0, the last number, to declare that period has become infinity and frequency has become zero and counting has stopped?
This makes no sense. If the question is not clearly stated, it cannot be answered.
What frequency does the personhear coming from thestationary car?
A person is running toward a stationary car at a speed of 6.0 m/s and another car is moving away at a speed of 25 m/s. The horn in each car is producing a sound with a frequency of 920 Hz. a) What frequency does the person hear coming from the stationary car? b) What frequency does the person hear coming from the moving car? c) What beat frequency does the person hear? d) The stationary car starts moving towards the person at a speed of 10.0 m/s. What is the new beat frequency heard by the person?
F=the frequency that the person hear. f=the car stationary frequency if the person is in front of the stationary car: F=(V(sound)+v(person)/V(sound) -v(car))f and if the person is behind the car: F=(V(sound)-V(person)/V(sound) +v(car))f Just put the numbers in these formulas
