The centripetal acceleration of the race car is 40500 mi/hr^2.
This can be calculated as the square of the velocity v divided by the radius r of the circular track:
a = v^2 / r
Substituting the given values of velocity v = 135 mi/hr and radius r = 0.450 miles, the centripetal acceleration a of the car is therefore
a = (135 miles/hour)^2 / (0.450 miles)
= 40500 miles/hour^2.

Explanation:
Liquefied salts in sea water make The ocean is salty because of the salt that dissolves in sea water. Seawater can become saturated with dissolved salts. Certain marine animals can remove these salts from sea water and produce protective shells or build a reef, when the water cannot hold anymore salt since water can only hold a certain amount of dissolved solids. During dry conditions, minerals are formed as the water evaporates then solids crystallize out of the water. On the other hand, atoms and ions arrange themselves and form mineral crystals when the magma-as an ash or lava ash cools above the ground or magma cools below the ground.
