Yeah, I don't see why r would be that distance either. It seems to me that 53.1° would be correct if the angle of the antenna was horizontal, but that would cause the intensity at the opposite mountain to be measured as zero.
I just did the math using the method you described and got the right...
Yes, all the numbers except the distance are the same in the problem; Webassign changes some of the values for each question. I finally got the answer 55.7 pW/m2 using Webassign's practice questions, though I'm still not sure how to do the problem. I just divided the answer I was getting by the...
Thanks! I assume you're talking about the intensity varying by sin2(θ)/r2 if it's a dipole. Thanks for pointing that out; this is a Webassign problem, so that bit wasn't given.
I tried introducing this into the equation, but I still must be doing it wrong. It seemed to me that the power...
The problem:
You and your engineering crew are in charge of setting up a wireless telephone network for a village in a mountainous region. The transmitting antenna of one station is an electric dipole antenna located atop a mountain 2.00 km above sea level. There is a nearby mountain that is...
