Question

Radar is used to determine distances to various objects by measuring the round-trip time for an echo from the object. (a) How far away (in m) is the planet Venus if the echo time is 1300 s? 19.5*10**10 m (b) What is the echo time (in 84s) for a car 74.0 m from a Highway Patrol radar unit? .493 84s (c) How accurately (in nanoseconds) must you be able to measure the echo time to an airplane 12.0 km away to determine its distance within 10.5 m? ns

Step 1

For the distance to Venus, we know that the echo time is 1300 s. Since the radar signal travels to Venus and back, we need to divide the time by 2 to get the time it takes for the signal to travel one way. So, the time it takes for the signal to travel to Venus is Show more…
