Why the frequency of aeroplanes is 400 Hz?
Higher the fequency , higher the speed. Similarly,freq is inversely proportional to the the flux , higher the freq lower the flux requirement hence lower the winding req. which will reduce the weight ( this is necessary req. in operation of Aeroplane) of the winding The higher frequency allows a lighter transformer. Doubling the frequency allows the transformer's iron core to be half the weight. So 400 Hz allows light transformers (and motors) to be used.
What is the relationship between frequency and bandwidth in terms of data transmission?
Frequency and bandwidth are closely related in data transmission. Frequency refers to the number of cycles per second that a signal oscillates at, while bandwidth is the range of frequencies that a signal occupies. In data transmission, higher frequencies allow for more data to be transmitted in a given amount of time, resulting in a wider bandwidth. Therefore, a higher frequency signal typically has a larger bandwidth and can carry more information.
What purpose of heat number write on the pipe?
Depends on what pipe you are asking about. Most pipe such as PVC has a max heat rating for internal and external temperatures. this is why regular white PVC should never be used for hot water from a hot water heater which can be 120 degrees (F) or more and melt regular PVC. That is why they recommend using CPVC which has a higher temperature rating. Depends on what pipe you are asking about.

What is the difference between frequency and pitch?
The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch
In GSM which frequency uplink or downlink is greater?
The main reason of selecting a lower frequency for up-link channel in GSM is because of free space path loss. The more is the frequency the more is the loss. As mobile phones, being a battery driven device, have limitation in terms of power we should always look for lower path loss. Whereas BTS antennas can transmit the signal (in down-link channel) with a comparatively high power, which will compensate the path loss. And that is why it is chosen to have lower frequency for up-link and higher frequency for down-link in GSM standards. The same theory applies in almost all type of radio communication. NOTE: Frequency and power are independent of each other. For example you can control the transmission power of BTS antenna, which still transmits in the same frequency.
Why internal fertilization often produces fewer offspring than external fertilization?
Internal fertilization utilizes a placenta and womb and this limits the number of offspring that can be produced. Internal fertilization also has a higher birthrate than external fertilization.
What changes the frequency of things?
The frequency of things can be changed by altering the speed at which they occur. Factors such as the rate of vibration, rotation, or oscillation can affect the frequency of events. Additionally, external influences like temperature, pressure, or tension can also impact the frequency of phenomena.
What is gain roll off?
A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.
What does resonant frequency mean?
Resonant frequency is the natural frequency at which an object vibrates most efficiently when disturbed. It is the frequency at which an object naturally oscillates without any external force. For example, pushing a swing at its resonant frequency will cause it to swing higher with minimal effort.
Is Natural frequency and Resonance of a Cantilever Beam will be same?
No, the natural frequency and resonance frequency of a cantilever beam are not necessarily the same. The natural frequency is the frequency at which a system oscillates without any external forces, while the resonance frequency is the frequency at which a system is most responsive to external forces. In a cantilever beam, the resonance frequency is typically higher than the natural frequency.
What is internal friction in liquid?
Internal friction in a liquid refers to the resistance encountered by the liquid molecules as they flow past each other. It is a measure of how easily the liquid can respond to external forces and deformations. Internal friction affects the viscosity of the liquid, with higher internal friction leading to higher viscosity.
Does higher frequency correspond to higher pitch?
Yes, higher frequency corresponds to higher pitch.
What is the frequency of thought?
The frequency of thought is subjective and varies depending on the individual. It is influenced by factors such as cognitive processes, emotions, external stimuli, and personal experiences. Some people may have a higher frequency of thought due to a more active mind, while others may have a lower frequency.
What changes the frequency of an xylophone?
The pitch. The higher the pitch, the higher the frequency.
How a sound pitch and frequency are related?
Higher the frequency higher the pitch.
How sound pitch and frequency are related?
Higher the frequency higher the pitch.
What would it be with a frequency of 100000 hertz?
A frequency of 100000 Hz means there are 100,000 cycles per second. In the audio range, this frequency is on the higher end, so it may be difficult for humans to perceive it directly as a distinct pitch. Devices like ultrasonic sensors and medical imaging machines operate in this frequency range.
