(C) The formula for the maximum line-of-sight distance $d$ for a transmission tower of height $h$ is given by $d = \sqrt{2hR}$,where $R$ is the radius of the Earth.Given: $h = 245 \ m$,$R = 6.4 	imes 10^6 \ m$.Substituting the values:$d = \sqrt{2 	imes 245 	imes 6.4 	imes 10^6}$$d = \sqrt{490 	imes 6.4 	imes 10^6}$$d = \sqrt{3136 	imes 10^6}$$d = 56 	imes 10^3 \ m$$d = 56 \ km$.Thus,the broadcast can be received up to a distance of $56 \ km$.

The $T.V.$ transmission tower in Delhi has a height of $245 \ m$. The distance up to which the broadcast can be received (taking the radius of earth to be $6.4 \times 10^6 \ m$) is........$km$ :
