A student slides a book over two different surfaces. First, she slides the book across a desk. Next, she slides the same book on the carpet. She exerts the same force onto both books. Which surface would cause a greater change in the velocity of the book? Explain your answer. A. Desk

C. The change would be the same

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
