Final answer:
To estimate the power value at a distance of 1.7 km, we can use the inverse cube-power law. Set up a proportion and solve for the power at 1.7 km.
Step-by-step explanation:
To estimate the power value at a distance of 1.7 km from the base station, we can use the inverse cube-power law. This law states that the power decreases with the cube of the distance from the source.
Let's set up a proportion using the given power measurement at 425 m:
-
- Power at 425 m / Distance at 425 m^3 = Power at 1.7 km / Distance at 1.7 km^3
-
- 25 µW / (425 m)^3 = Power at 1.7 km / (1.7 km)^3
Solving for the power at 1.7 km, we can find a reasonable estimate.
