I need the answer as soon as possible Q-1) Choose one of the different choices indicated in the parenthesis such that the following sentenceshave correct meaning.1. The main purpose of modulation is to (Combine two waves of different frequencies, achievewave shaping of the carrier wave, Transmit low frequency information over long distances efficiently,produce sidebands).2. 100% modulation is produced in AM when carrier (Frequency equals signal frequency,Frequency exceeds signal frequency, Amplitude equals signal amplitude, Amplitude exceeds signalаmplitude).3. If Signal Amplitudeperiodic and its power exist, Non periodic and its energy exist, none of them).4. Time shifting (Halving, doubling, squaring, has no effect on) the energy.5. For the signal shown beside, the energy of x(t) is equal (1,4, 3/4, 4/3) joule- 0 as It| → oo, the signal is (Periodic and its power exist,Non(1)x6. DSB/SC is called suppressed-carrier because (The spectrum is centered at the frequency wc,Both the positive and negative frequencies bandwidth of f(t) is doubled, The spectral density of p(t) hasno identifiable carrier in it, none of them).7. The extra carrier signal added to the modulated signal in order to achieve synchronousdemodulation at the receiver is called (IF Carrier, Pilot Carrier, Composite Carrier, Subcarrier).8. Given a carrier frequency of 100 kHz and a modulating frequency of 5kHz the bandwidthof AM transmission is (5, 200, 10, 20)kHz.9. In an AM system, full information can be conveyed by transmitting only (The carrier, Thesideband, The lower sideband, Any one of sidebands).10. A non-coherent type modulation detector does not need synchronization with the transmitter.An example of non-coherent detector is the (PLL, Envelop detector, Phase detector, Quadraturedetector).uрper

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end).

The wording that I am running into with questions such as "The number of conductors required to be installed between three-way and four-way switches is " is confusing. The text is not expalining this in a way that I am understanding anything other than grounding conductor, which is optional unless I am using a metal box. So what type of "conductor" is beng discussed?
