Answer:
14 seconds
Explanation:
Distance covered by sports car is measured with 21*t where t is time.
Distance covered by police is measured with at^2/2(t-time, a-acceleration) as it doesnt have starting velocity. If the distances are equal(police catches sport car)
then we have 21t=3/2*t^2 Solving this equation we get t=14 & t=0;
excluding the starting point we have 14 seconds
The natural factor that is most likely to support the formation of an oceanic island is the rise of magma from the seafloor. Oceanic islands are also otherwise known as volcanic islands. When volcanoes erupt, they create layers of lava that break the surface of the water. When the tops of the volcanoes emerge, an island is created.<span> </span>
Around 70-72% of earth’s surface is covered in water (most of it is salt water).
Hope this helps.
Static friction - the friction that occurs when a force is being applied on a still object.
Sliding friction - the friction that occurs upon a moving object; it is always lower than the static friction of the same object.
Rolling friction - the friction on a rolling object; it is actually a form of static friction with the contact point of the wheel with the surface.
