Explanation: Wind turbines generate energy by moving. (Kinetic energy is movement.) Wind turbines, in more detail, are pushed by the wind which causes a transfer of kinetic energy which is then converted by the turbine into electrical energy.
Answer:
Synthetic fibers are made from synthesized polymers of small molecules.
Explanation:
The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a chemical that bonds two adjacent carbon atoms.
It's a covalent bond. The two atoms connected are oxygen and hydrogen. Neither one is a metal of any kind
