Answer:
Explanation:
From the equation we are told that:
Velocity of French sub
Velocity of U.S. sub at
French Wave Frequency
Velocity of wave
Generally the equation for Signal's frequency as detected by the U.S. is mathematically given by
Doppler effect
Answer:
A light year is the distance light travels in a year. ... And an astronomical unit is the average distance between the earth and the sun. So the distance to the sun is by definition one AU. A parsec is the distance at which one astronomical unit subtends an angle of one second of arc.
Answer:
the objects mass is independent of its acceleration in free fall
Answer:
10512m
Explanation:
Using formula for Uniform Velocity v = D/t ;
where v = Velocity (367 m/s); D = Vertical distance (?); t = length of time of motion (?).
To find t we use the Kinematic equation D= v₀t + (1/2(at²));
where D = Distance traveled (4020m); v₀ = initial velocity (0); a = acceleration;
4020 = (0)t + (1/2(9.8)t²)
4020 = 1/2(9.8)t²
t² = 4020/(1/2(9.8))
t = √(4020/4.9).
back to our formula for Uniform Velocity v = D/t;
D = vt
D = (367)(√(4020/4.9))
D ≈ 10512m
