Answer: This is called the Doppler effect, where waves shift frequency and wavelength as the source travels towards you (higher frequency, shorter wavelength) or away from you (lower frequency, longer wavelength)
Explanation:
hoped this helped have a good day :)
Protons and neutrons in an atom are held together by a nuclear energy also called the strong force.
D.) Distance travelled / time ...........
Evidence of Chemical Change:
A car rusting
Leaves changing in October
The glow of a light bulb
A white cloudy substance occurs after mixing two substances
Burning toasts
A candle being lit
Evidence of Physical Change:
Water boiling
Yellow and blue paints mixed together
Wax melting
Crushing a rock with a hammer
Hope this helps!
Have a great day!
From laws of motion:
![S = ( \frac{v + u}{2} ) \times t](https://tex.z-dn.net/?f=S%20%3D%20%28%20%5Cfrac%7Bv%20%2B%20u%7D%7B2%7D%20%29%20%5Ctimes%20t)
Where S is the distance/displacement (as you would call it) which is unknown
v = final velocity which is 0m/s (this is because the car stops)
u = initial velocity which is 36m/s (from the data given)
t = time taken for the distance to be covered and it is 6s
Substitute the values, hence:
![S = ( \frac{0 + 36}{2} ) \times 6](https://tex.z-dn.net/?f=S%20%3D%20%28%20%5Cfrac%7B0%20%2B%2036%7D%7B2%7D%20%29%20%5Ctimes%206)
![S = (18) \times 6 \\ \\ S = 108m](https://tex.z-dn.net/?f=S%20%3D%20%2818%29%20%5Ctimes%206%20%5C%5C%20%20%5C%5C%20S%20%3D%20108m)
But this is merely the distance he travelled in the 6 seconds he was trying to stop the car.
Therefore, the distance between the car and the cows = 160-108
Distance = 52m
