Answer:
one forth.
Explanation:
car is moving at the speed of v
car stops, final speed = s
distance to stop the car = ?
using equation of motion
u_i² = u_f² + 2 a s
0² = v² - 2 a s
-ve sign is used because the car is decelerating.
![s = \dfrac{v^2}{2a}](https://tex.z-dn.net/?f=s%20%3D%20%5Cdfrac%7Bv%5E2%7D%7B2a%7D)
now, if the velocity of the car is 2v distance to stop
![s' = \dfrac{(2v)^2}{2a}](https://tex.z-dn.net/?f=s%27%20%3D%20%5Cdfrac%7B%282v%29%5E2%7D%7B2a%7D)
![s' = 4\dfrac{v^2}{2a}](https://tex.z-dn.net/?f=s%27%20%3D%204%5Cdfrac%7Bv%5E2%7D%7B2a%7D)
![s' = 4 s](https://tex.z-dn.net/?f=s%27%20%3D%204%20s)
![s = \dfrac{s'}{4}](https://tex.z-dn.net/?f=s%20%3D%20%5Cdfrac%7Bs%27%7D%7B4%7D)
now, the distance is one forth.
so, car with speed v has to cover one forth of the distance cover by car with speed 2 v.
The west coast of the united states receives two high tides and two low tides of varying heights per day. Tidal pattern is mixed semidiurnal tidal cycle
Sun and moon exert force on the ocean due to tides moves through the ocean Tide are very long period waves whose motion is directed by the effect of moon and sun . Tides originate in the ocean and progress toward the coastlines where they appear as the regular rise and fall of the sea surface.
An area has a diurnal tidal cycle if it experiences one high and one low tide every lunar day. An area has a semidiurnal tidal cycle if it experiences two high and two low tides of approximately equal size every lunar day An area has a mixed semidiurnal tidal cycle if it experiences two high and two low tides of different size every lunar day.

Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.For such a collision<span>, the forces acting between the two objects are equal in magnitude and opposite in direction</span>
