<u>Answer:</u> The frequency of the second harmonics is 168 Hz.

<u>Explanation:</u>

Fundamental frequency is the frequency associated with the ground state energy level. It is denoted by f_0

Second harmonic frequency is the frequency associated with the second energy level where n = 2. It is denoted by f_1

The relationship between fundamental and second harmonic frequency is:

f_1=2f_0

We are given:

f_0=84Hz

Putting value in above relationship, we get:

f_1=2\times 84=168Hz

Hence, the frequency of the second harmonics is 168 Hz.

Fundamental frequency, f₀ = 84 Hz

Second harmonic is  2f₀ = 2* 84 Hz = 168 Hz

1. Is a hurricane or a tornado deadlier on average?
Vilka [71]

Stoms or tornadoes cause about ten times more damage a year, on average, as hurricanes. Storms often cause more complete destruction than hurricanes because of their large size, long-term duration, and their varied potential for damage to property.

Storms can be very severe storms, hurricanes often last a long time, cover most of the earth and cause great damage. The wind from the strongest calves is stronger than the one from the strongest storms.
