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).

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.

The radius of earth is 8xx10^6m and the height of the TV tower is 100m. What will be the maximum range of the signal Transmission?

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)

The angle of elevation of the top of a tower from a point O on the ground, which is 450 m away from the foot of the tower, is 40^(@) . Find the height of the tower.

Suppose that the source of earth's magnetism is a magnetic dipole at the earth. Find the moment of this magnetic dipole if the strength of earth's magnetic field at the equator is 4xx10^(-5) T . Given , radius of the earth 6.4xx10^(6)mand(mu_(0))/(4pi)=10^(-7)T.m.A^(-1) .

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.
