Answered

The intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. Suppose intensity is 8000 units at a distance of 2 miles. What will the intensity be at a distance of 11 miles? Round your answer to the nearest unit.

Answer:

264 units

Step-by-step explanation:

8000(2/11)^2

8000(.181818...)^2

8000(.033058)

264.46

264

The intensity at distance of 11 miles be 264.46

What is Intensity?

Intensity is power per unit area. The area is measured on a plane perpendicular to the direction of wave propagation.

Given:

Intensity = 8000 units at 2 miles

Intensity inversely of square of the distance

So,

=8000(2/11)²

=8000*4/121

=32000/121

=264.46
