in mobile phone network how many times as strong would a signal be expected to be at 200 m from a base station, compare with at 600 m?
is it 81 or 9 or 3 or 0.3 or 0.1 or 0.01
To determine the strength of a signal at different distances from a base station in a mobile phone network, we can use the inverse square law. According to the inverse square law, the power of a signal decreases with the square of the distance from the source.
To calculate the ratio of signal strength at two distances, we can divide the square of the first distance by the second distance squared. Let's calculate this for the given distances:
Signal strength at 200 m: (200/600)^2 = 1/9 = 0.1111
Signal strength at 600 m: (600/600)^2 = 1
Therefore, the signal strength at 200 m from the base station is approximately 0.1111 (or 1/9) times as strong as at 600 m.
Based on the provided options, the closest answer is 0.1.
