The radar system at an airport broadcasts 11 GHz microwaves with 150 kW of power. An approaching airplane with a 30 m2 cross section is 30 km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all directions.

What is the electric field strength of the microwave signal received back at the airport 200 \mu s later? Express your answer in μV/m.

= μV/m

- I'm not sure if the 11 GHz or 200 μs is necessary in the problem or not. All the examples I've looked at that are similar to this problem don't include those two values in their calculations.

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
