Chen is testing the friction of three surfaces. he pushes the same ball across three different surfaces with the same force and measures the distance of each ball. the ball moved ten inches across surface 1, six inches across surface 2, and fifteen inches across surface 3.

which could most likely describe the three surfaces?

a> surface 1 is ice, surface 2 is gravel, and surface 3 is blacktop.
b> surface 1 is gravel, surface 2 is ice, and surface 3 is blacktop.
c> surface 1 is blacktop, surface 2 is gravel, and surface 3 is ice.
d> surface 1 is blacktop, surface 2 is ice, and surface 3 is gravel.

The correct answer is Option C.

Explanation:

We are given three surfaces and the distance traveled by the object on that surface.

Frictional force depends on the mass of the object and the surface in contact. Smoother the surface, more distance will be traveled by the object and vice-versa.

In the question, the distance traveled by the object on 3 surfaces are:

Surface 1 = 10 inches

Surface 2 = 6 inches

Surface 3 = 15 inches

From the above information, surface 3 must be the smoothest of all the surfaces. Hence, this surface is ice.

The distance traveled is the lowest on Surface 2 which means that this is the roughest surface of all. This surface will be gravel.

And, surface 1 will be blacktop.

Therefore, the correct answer is Option C.

the ratio of the conjugate base to the acid required to attain the desired ph.
