A radar pulse returns 2.0 × 10−⁴ seconds after it is sent out,having been reflected by an object.What is the distance between the radar antenna and the object? (c = 3.00 × 10⁸ m/s) A) 3.0 × 10⁴ m B) 4.5 × 10⁴ m C) 9.0 × 10⁴ m D) 6.0 × 10⁴ m

The distance traveled by the pulse is twice the distance between the antenna and the object. So, the distance between the antenna and the object is:d = (2.0 × 10−4 s) × (3.00 × 108 m/s) / 2 = 3.0 × 104 m
