I believe it is the first one.
This is because of the Doppler Effect.
The Doppler Effect is when the frequency of the wave changes for an observer moving relative to the wave source.
Basically, as the police car moves away from you, the distance between you and the car increases, which makes the sound waves spread out.
The answer would be C. 80%
Put 160 over 200 and find the GCF
160/200÷40=4/5=80%
Answer:
$ 3085713685.71
Explanation:
= Actual wavelength = 700 nm
= Changed wavelength = 500 nm
Let the wavelength of red color be 700 nm and green be 500 nm
Change in wavelength is
We have the relation
The speed of the vehicle is 85714285.7143 m/s
By how much was the car speeding
The number of 10 km/h in the above speed
Cost of the ticket
The cost of the ticket is $ 3085713685.71
Answer:
☆<《<em><u>HOPE IT WILL HELP YOU</u></em><em><u> </u></em>》>☆
Explanation:
The probability of getting 4 is 1
Make the base of the building zero. Then the initial distance is 100m, final distance unknown x. Use gravity, time and initial velocity to solve for final distance.
x - 100 = (0)(5) +(1/2)(-9.81)(5^2)
x - 100 = 0 - 122.625
x = -122.625 + 100
x = -22.625 m below ground
