1.	A transmitting antenna at the top of the tower has a height 18 m and the height of the receiving antenna is 32m. The maximum distance between them for satisfactory communciation in line of sight mode is (Radius of earth`= 6.4xx10^(6)m`)A. 15.15kmB. 21.25kmC. 30.45kmD. 35.42km.
Answer» Correct Answer - D here `h_(t)=18m,h_(R)=32m`, `R6.4xx10^(6)m=64xx10^(5) m` The maximum line or sight distance `d_(m)=sqrt(2Rh_(T))+sqrt(2Rh_(R))` `=sqrt(2xx64xx10^(5)xx18)+sqrt(2xx64xx10^(5)xx32)` `=112xx10^(2)xxsqrt(10) m=35417.5m=35.42km`

A ` 1 KW ` signal is transmitted using a communication channel which provides attenuatiom at the rate of ` - 2 dB per km` . If the communication channel has a total length of ` 5 km` , the power of the signal received is [ gain in `dB = 10 log ((P_(0))/(P_(i)))]`A. 900WB. 100WC. 990WD. 1010W
Assertion: Amplification is necessary to compensate for the attenualtion of the signal in communication system. Reason: Amplification is the process of increasing the amplitdue and consequently the strength of a signal using an electronic circuit.
