Deduce an expression for the distance from which the T.V. signals can directly be received from a T.V. tower of height h.

What are T.V. signals? How can they be received?

A TV transmission tower has a height of 140 m and the height of the receiving antenna is 40 m. What is the maximum distance upto which signals can be broadcasted from this tower in LOS (Line of Sight ) mode ? (Given : radius of earth = 6.4xx10^(6) m).

The height of a T.V. tower is 300 m. What is the maximum distance upto which T. V. signals can be received ? ( R = 6400 km)

The T.V. transmission tower in Delhi has a height of 240 m. The distance up to which the broadcast can be received, (taking the radius of earth to be 6.4xx10^(6)m) is

A TV transmission tower has a height of 140 m and the height of the receiving antenna is 80 m. What is the maximum distance upto which signals can be broadcasted from this tower in LOS (Line of Sight) mode? (Given: Radius of earth = 6.4 xx 10^6 m )

find the minimum colatitude which can directly receive a signal from a geostationary satellite.

The T.V.Transmission tower in Delhi has a height of 240m. The distnace up to which the broadcast can be received (taking the radius of earth to be 6.4xx 10^(6) is:

A body, rpojected horizontally with a speed u from the top of a tower of height h , reaches the ground at a horizontally distance R from the tower. Another body, projected horizontally from the top of a tower of height 4h , reaches the ground at horizontal distance 2R from the tower. The initial speed of the second body is
