Explanation:

Wind turbines generate electricity by following simple principle. Moving wind transfers energy to the to the blades of the wind mill which results in spinning of the blades. These blades are connected to internal shaft which also starts spinning. This spinning of shaft generates electricity which is further distributed to electrical substations to provide electricity to homes and businesses.

Step 1: Wind moves the blades of the turbine.

Step 2: Internal shaft spins

Step 3: Generator produces electricity

Step 4: Distribution lines carry electricity to substation

Marta_Voda [28]

Answer:

Explanation: In the previous section we listed four characteristics of radioactivity and nuclear decay that form the basis for the use of radioisotopes in the health and biological sciences. A fifth characteristic of nuclear reactions is that they release enormous amounts of energy. The first nuclear reactor to achieve controlled nuclear disintegration was built in the early 1940s by Enrico Fermi and his colleagues at the University of Chicago. Since that time, a great deal of effort and expense has gone into developing nuclear reactors as a source of energy. The nuclear reactions presently used or studied by the nuclear power industry fall into two categories: fission reactions and fusion reactions

"What makes a bond polar"?
r-ruslan [8.4K]

Answer:

The answer to your question is: letter A.

Explanation:

A Covalent bond polar is between 2 non metals where one atom is bigger than the other one so the distribution of charges creates this polarity.

A. One atom attracts shared electrons more strongly than the other atom  This is the correct definition of bond polar, one element is bigger and stronger than the other element.

B. One atom has transferred its electrons completely to another atom  This definition is incorrect, it is the definition of ionic bonding.

C. A sea of electrons has been created between the elements  This definition is incorrect for the polar bond, it describes a metallic bonding.

D. Two atoms are sharing electrons with equal attraction This definition is incorrect for a polar bond, but is the correct definition for nonpolar bonding.
