Height h(400=m) from the ground at place A, from which the readiowaves can be transmitted. There is a receive at station B on earth at a distance d(=125km), which can receive the signal from station A. The radiowaves can reach the station B, either through earth's atmosphere or through satellite. There are four main layers in earth's atmosphere named D,E, F_(1) and F_(2) which play effective role in radio communication. The electron density of these layers is 4xx10^(8), 2xx10^(11),5xx10^(11) and 8xx10^(11)m^(-3) . The radius of the earth is 6.4xx10^(6)m . If the station A sends the T.V. signals, then the maximum area on earth upto which T.V. transmission can be received on earth is (average population density around the tower is 1000 km^(-2) )

During an experiment, a signal from a spaceship reahced the ground station in five minutes. What was the distance of the speceship from the ground station ? The signal travels at the speed of light, that is, 3 xx 10^(8) m//s .
