A radar pulse returns 3.0 x 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 x 10⁸ m/s) A)9.0 x 10⁴m B)4.5 x 10⁴ m C)6.0 x 10⁴ m D)1.0 x 10⁴ m

Question

The distance traveled by the radar pulse can be calculated using the formula:

distance = speed x time / 2

Here, speed = c = 3.00 x 10^8 m/s
time = 3.0 x 10^-4 s (as given in the question)

Substituting the values, we get:

distance = c x t / 2 = (3.00 x 10^8 m/s) x (3.0 x 10^-4 s) / 2 = 4.5 x 10^4 m

Therefore, the distance between the radar antenna and the object is 6.0 x 10^14 m, which is closest to option C.
