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.

<u>Answer:</u> The frequency of the light is
<u>Explanation:</u>
The equation used to calculate the energy for a transition, we use the equation:
where,
n = principal energy level
Calculating the energy difference:
To calculate the energy of the light for a given frequency, we use the equation given by Planck, which is:
where,
E = energy of the light =
h = Planck's constant =
= frequency of the light = ?
Putting values in above equation, we get:
Hence, the frequency of the light is
Answer:
Crystallization. Magma cools either underground or on the surface and hardens into an igneous rock. As the magma cools, different crystals form at different temperatures, undergoing crystallization. For example, the mineral olivine crystallizes out of magma at much higher temperatures than quartz.
