Answer:
f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.
Explanation:
Answer:In fact, engineers have completely changed the world we live in, from modern homes, bridges, space travel, cars and the latest mobile technology. Innovative ideas are at the heart of what engineers do, and they use their knowledge to create new and exciting prospects and solve any problems that may arise.

Answer:
116 ft/s
Explanation:
D = 0.10x² – 3.00x + 22.0
1019.50 = 0.10x² – 3.00x + 22.0
0 = 0.10x² – 3.00x – 997.5
0 = x² – 30x – 9975
Solve with quadratic formula:
x = [ -(-30) ± √((-30)² − 4(1)(-9975)) ] / 2(1)
x = [ 30 ± √(900 + 39900) ] / 2
x = (30 ± 20√102) / 2
x = 15 ± 10√102
x ≈ 116
