The frequency of choice-3 is
(3 x 10⁸ m/s) / (500 m) = 600,000 Hz.
That number is the 600 near the bottom of the AM radio dial.
Answer:
a = -16.9 ft/s²
Explanation:
81.8 mi/hr(5280 ft/mi / 3600s/hr) = 120 ft/s
a = Δv/t = (0 - 120) / 7.1 = -16.9 ft/s²
if the initial direction is taken as the positive direction.
Race relations throughout history has changed over and over. But as far as the modern world race relations have went through all three. Diversity is far more common now ( which I think is positive) .
