A jet flies over the ocean. A sound wave travels from the jet to the surface of the ocean. Almost none of the energy from the
sound passes into the water. The diagram below illustrates the path of the sound wave.
Which of the following statements about this scenario is true?
A. Both the direction and the speed of the sound waves remain the same.
B.
The direction of the sound waves changes but its speed remains the same.
C. The speed of the sound waves changes but its direction remains the same.
D.
Both the direction and the speed of the sound waves change.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
