As the fly approaches you, the observed frequency of the hum will increase. This is due to the Doppler effect, where the frequency is higher when the source of the sound is moving towards the observer. To calculate the observed frequency, you can use the formula: observed frequency = original frequency x (speed of sound + speed of fly) / (speed of sound).
What else can I help you with?
What the expected frequency of a person that having tongue rolling ability and attached earlobe?
The expected frequency can be calculated using the product rule in probability. If we assume that the ability to roll the tongue and having attached earlobes are independent, then we can multiply the frequencies of each trait in the population to get the expected frequency of individuals with both traits.
If the frequency of a wave traveling in a rope is doubled what will happen to the speed of the wave?
Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
What is the relationship between intensity and frequency?
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
What is short frequency?
Well, I assume you are talking about waves, am I correct? Frequency is the distance between the crest and the trough of a wave. Gamma rays are the waves of highest frequency that we know of. Ultraviolet possesses a frequency just above the frequency of visible light (remember ROYGBIV). Descend in frequency beneath red and you'll come to infrared. While snakes can detect this (I am not yet sure how) the human eye cannot detect anything of this low frequency although we often use this in modern technology (note nightvision goggles). The higher the frequency, the smaller the wavelength and vice versa. Radio waves have an extremely short frequency and an extremely long wavelength.
What is the speed of the solar signal in water with a frequency of1000 hertz and wavelength of 1.5?
I assume that a "solar signal" means light. Light moves at approximately 262 million meters per second in water, regardless of the frequency or wavelength of the light. Also, if light has a frequency of 1000 Hz, then it has a wavelength of 300 kilometers. The speed of light, c, is equal to the product of the frequency and the wavelength. In other words, c=f*w
The herzt is the unit of measurement for?
Its a unit for frequency. Specifically its the number of cycles per second. I assume you mean hertz - The unit of frequency
Is alpha the probability that the test statistic would assume a value as or more extreme than the observed value of the test?
Alpha is the probability that the test statistics would assume a value as or more extreme than the observed value of the test, BY PURE CHANCE, WHEN THE NULL HYPOTHESIS IS TRUE.
In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
What causes the oscillation at a certain frequency in an inkjet printer?
I assume you mean the frequency at which the head moves back and forth. If this happens only at a certain frequency, then it sounds as if that is caused by resonance - which happens when the excitation (in this case, the head moving back and forth) has a similar frequency to the object's (the printer's) natural frequency.
Why is radiation with the shortest wavelength actually the most powerful?
I assume you are talking about electromagnetic radiation.If the wavelength is shorter, the frequency is larger. And the energy per photon is directly proportional to the frequency.
How does the wavelength of a light wave change if the frequency in increased by a factor of 3 Assume the speed of the wave remains unchanged?
i
4301.85GHZ mean on system properties?
I assume you mean Mhz. Depending on where in sys properties you are looking at, this number refers to the CPU clock frequency.
Who was first observed the Milky Way galaxy?
The Milky Way can be seen with the naked eye, so we can assume that people have been observing it before written history.
If the frequency of a wave traveling in a rope is doubled what will happen to the speed of the wave?
Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
What the expected frequency of a person that having tongue rolling ability and attached earlobe?

Need of drives in motor?
Drives - I assume you are referring to Variable frequency Drives. The drives are useful when a motor needs to rotate at different speeds when in operation with out stopping it.
What is the ratio of frequency of visible light to frequency of audible sound?
The lowest frequency of visible light ... assume wavelength = 750 nm ...is around 400,000 GHz.The highest frequency of audible sound is around 20 KHz.So the smallest ratio ... lowest frequency of light to highest frequency of sound ...is 4 x 1014/2 x 104 = 20 billion .
