Final answer:
The separation distance between the radar source and the object can be found by multiplying the round-trip time for the radar pulse by the speed of light.
Step-by-step explanation:
The distance between the radar source and the object can be found by multiplying the round-trip time for the radar pulse by the speed of light. In this case, the round-trip time is 9.0 × 10⁻⁴ s. The speed of light is approximately 3 × 10^8 m/s. So, the separation distance would be:
distance = round-trip time × speed of light
distance = (9.0 × 10⁻⁴ s) × (3 × 10^8 m/s)
distance ≈ 270,000 meters = 270 kilometers
