Answer:
56 km
Step-by-step explanation:
Given The height of TV tower at a certain place is 245.m. the maximum distance up to which its programme can be received?
Assuming radius of the earth is 6.4 x 10 ^6 m we can calculate as
h = 245 m
So √2 h R = √2 x 245 x 6.4 x 10^6
= √3136 x 10^6
= 56000 m = 56 km
So the maximum distance up to which its programme can be received is 56 km.
