BRAINLIESIT IF CORRECT Sound waves travel as particles of matter collide and transfer energy.

True

False

6

True

Explanation:

Sound waves require a medium/substance to transmit through, for example, sound waves cannot travel through the vacuum of space . The medium, water or air, itself does not move in bulk with the wave . The medium's particles carry kinetic energy from one point to another . This is when the wave transmits through its medium, the particles simply vibrate as the wave passes through. The vibrations carry the energy from one particle to the next. This means that the sound wave is carried through the medium.

*Note: Sound waves need particles to travel but light does not.

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.
