i need the answer quickly Q1) Answer by true or false for ten of the following items, and correctthe false one4- The smooth walls horn antenna has smaller sidelobelevel compared to corrugated horn antenna.5. The parabolic surface, which is obtained by rotating aparabolic curve on its axis, satisfies the equation(y=f6x).6- Typical methods used for array synthesis are, thecosine tapering and cosine squared tappering7- The condition for bending the electromagnetic wavesdown to earth is curvature of the earth. 8- The mainreason that causing travelling wave attenuation, is thepresence of ionizedlayers9- The reception of long sky wave is better through thenight than the daytime because of the radiation of thesun.10- The propagation of short sky wave depends onsome factors, which are eddy currents,clouds, and gamma rays.11- The methods used for VHF propagation aretropospheric scatter, ionospheric scatier,and meteor trails.12- Trapping usually occurs at millimeters wavelengths.13-lonization columns produced by meteors in theE-layer region are capable of reflectingwaves. The meteor trails are either of high density or oflow density. The probability of occurrence of the latter ishigh..

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 end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3.
