A TV tower is 80m tall. Calculate the maximum distance upto which the signal transmitted from the tower can be received (Taking radius of the earth = `6.4 xx 10^6m`).

A TV tower is 80 m tall. Calculate the maximum distance upto which the signal transmitted from the tower can be received. Given, earth's radius = 6400km.

Define amplitude modulation. The height of a TV tower is 125m. Find the maximum distance up to which transmitted signal from the tower is available (radius of the earth =6.4 xx 10^(6) m).

Define amplitude modulation. The height of a TV tower is 125 metre. Find the maximum distance up to which transmitted signal from the tower is available (Radius of the earth= 6.4xx10^6m )

Name the type of wave which are used for line of slight (LOS) communication. What is the range of their frequencies? A transmitting antenna at the top of a tower has a hight of 20 m and the height of the receiving antenna is 45 m. Calculate the maximum distance between them for satisfactory communication in LOS mode. (Radius of the earth = 6.4 xx 10^(6) m)

A TV transmission tower has a height of 240 m. Signals broadcast from this tower will be received by LOS communication at a distance of (assume the radius of earth to be 6.4 xx 10^(6) m)

A satellite of mass 1000 kg moves in a circular orbit of radius 7000 km around the earth. Calculate the total energy required to place the satellite in orbit from earth's surface. Take Radius of earth =6400 km and g=10 m*s^(-2) .

At what height is the transmitting antenna to be placed to make a TV transmission up to a distance of 32 km? The radius of earth = 6.4 xx 10^(6) m.

A TV tower has a height of 100 m. How much population is covered by the TV broadcast if the average population density around this tower is 1000 km^(-2) ? Given, radius of the earth = 6.37 xx 10^(6) m.

If the height of a television tower is 300 m, how far would the TV transmission be possible? (Given, the radius of earth = 6400 km )
