Bob is studying waves in science and learns that the energy of a wave is directly proportional to the square of the waves
amplitude. If the amplitude of a wave changes from 2m to 1m, what should he predict as the effect on energy of the wave?
A. The energy is halved.
B. The energy is doubled.
C. The energy is quartered
D. The energy is quadrupled.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
