C. design extra reinforcements in the building's windows so that they
can withstand the vibrations from sonic booms.
Explanation:
The engineer should design extra reinforcements in the buliding's windows so that they can withstand the vibrations from the the sonic booms.
When the supersonic craft takes off, it releases huge vibrations and this fores objects nearby to vibrate at their own natural frequency. This phenomenon is known as resonance.
- When objects vibrates at a natural frequency due to the vibration of another body nearby, it leads to resonance.
- Sonic booms releases a massive burst of energy that forces structures around to want to vibrate.
- Windows have to be reinforced in order to prevent them from shattering when the craft takes off.

Answer: <span>COS has a dipole moment because it is asymmetric and the dipole moments do not completely cancel.
Explanation: As we know in case of
CO</span>
₂ the net dipole moment is zero because the molecule is symmetrical and is Linear in shape. Hence, the two dipoles cancel each other.
While in case of
COS, the molecule is still Linear but is Asymmetric. The Oxygen atom being more Electronegative attract the electron more from Carbon atom as compared to S, Hence making giving a Dipole Moment of
0.65 D.
