Responsible because we feel less stressed when others help out with our responsibilities.
I will convert the unit of distance to SI unit for simplification.
1 mile = 1.6 km
Therefore, 0.245 mile = 0.245×1.6 = 0.392 km = 392 meters
Radio waves travels back after bouncing off from car.
Therefore, total distance traveled by radio waves = 2×392 = 784 meters.
Speed of radio waves = 3×10⁸ m/s
Therefore, time take by radar beam to <span> travel to a car and back = 784/3</span>×10⁸
=2.61×10⁻⁶sec
Well, they're still being formed as fossils break down. However, we are using them faster than they can be replenished, as they are made over a very, very slow process.
