Who? Don't you mean what? Your question makes little sense. If the frequency is constant as you say, then it cannot be changed. However, if talking about radio equipment constant frequencies can be changed through a process known as Mixing. That is a second source of constant frequency is mixed in with the other frequency and you will get the sum and the remainder output. In other words, if the frequency of the 1st source is say 5 mhz and the frequency of the other source is 2 mhz, then on the output you would get 7 mhz and 3 mhz. This can be done with other frequencies also. If you are talking about 60hz (USA AC frequency), that can be changed using a VFD or Variable Frequency Drive.
At high frequency, capacitor can be considered as 1. Short Circuit in AC analysis. 2. Open Circuit in DC analysis. {because Xc= 1/(2*f*pi) where f= supply frequency,pi=3.14} As at high frequencies, in DC analysis, capacitor will be open circuited & can block the DC signal while AC signal is allowed to pass through.. Hence, this capacitor will act as a blocking capacitor for DC supply.
It depends on the length of th cable and the diameter of the copper cable used.
Generally th e current drawn by the transformer in no load condition is being utilised by the iron losses and the angle b/w voltage and current is known as hystresis angle.
The cost for a replacement stepper motor wil depend greatly on the exact type of motor to be relced. Stpper motors are availbl in 100's of varieties at the low end th cost is $25,but can reach into the thousands.
Safe working practices are systems of work that are carried out in a safe manner for any given task. Although most businesses use safe systems as a matter of course, it is best to record these and make sure they are communicated to your employees by giving them a copy of th recording during their training.
Frequency and distance are directly proportional the higher the frequency the more distance for the sound to dissipate th lower the frequency th shorter the distance for the sound to dissipate
A band-limited signal is one in which the Fourier transform is zero above a certain frequency. In other words it's a signal that ahas a finite frequency content. The simplest case is a pure sinusoidal signal, whose Fourier transform consists of a delta function centred on the frequency of the signal. A band-limited signal can be reconstructed exactly if it is sampled at at more than twice the maximum frequency present in the signal. A time-limited signal is a signal that is zero above a finite. An example of this would be a short pulse. The reason a signal cannot be both band-limited or time-limited is due to their relationship via the Fourier transform. One can show it is impossible for the Fourier transform of a signal with compact support ie either time or band-limited, to also have compact support. A time-limited signal must have a continuous frequency spectrum existing over all possible frequencies and a band-limited signal can only arise from signal existing for all time. Note this indicates in reality it is impossible to have a truly band-limited signal as it would take infinite time to transmit, but it is nonetheless a useful concept and we can produce nearly band-limited signal to a high degree of accuracy.
The period would decrease, since the period is simply the reciprocal of the frequency. Also, the wavelength should decrease - since the speed of a wave usually doesn't depend significantly on the frequency, and the wavelength is equal to the speed divided by the frequency.

To answer this question we need the centuries. "Th" is not a word or number.
The slope of a time-distance chart would be a constant. The slope of a time-velocity chart would be 0.
