(a)
Interpretation:
The given material cobalt/tungsten carbide has to be classified as ceramic-ceramic or ceramic-metal and or ceramic polymer.
Concept introduction:
Ceramic composites:
Materials which are inorganic, non-molecular solids, crystalline (quartz) and amorphous (glass) are known as ceramics. Ceramics are brittle in nature and susceptible to break. They are hardened by combining ceramic powder before sintering with fibers such as boron and silicon carbide. The obtained hybrid materials are known as ceramic composites.
Ceramic-metal composites:
Similar to ceramic composites but in this composite fiber and matrix are made of ceramic and metal. Example: Aluminum-strengthened boron fiber.
Ceramic-polymer composites:
Similar to ceramic composites but in this composite fiber and matrix are made of ceramic and

- Order the following organic reactions by relative rate. That is, select '1' next to the reaction that will have the fastest initial rate, select '2' next to the reaction that will have the next fastest initial rate, and so on. If two reactions will have very similar initial rates, you can select the same number next to both. If a reaction will have zero or nearly zero initial rate, don't select a number and check the box in the table instead. Note: the "Nu" in these reactions means "a generic nucleophile." ملی CI :Nu 2 он 3 H Reaction Relative Rate (Choose one) ▼ Nu :CI: zero or nearly zero Nu :Nu bi (Choose one) zero or nearly zero : Nu لی Nu :H (Choose one) zero or nearly zeroarrow_forward9:12 AM Tue Mar 4 66% Problem 38 of 15 Submit Curved arrows are used to illustrate the flow of electrons.
