A small hummingbird flying around beats its wings with a frequency of 170 Hz. If the wavelength of the sound wave produced is 2
1 answer:
The given information in the question is :
Frequency = 170 Hz
1 Hz =
Frequency = 170
Wavelength given = 2 m
Speed is unknown which we need to calculate.
Speed can be calculated by using the formula : Speed = wavelength X frequency
By plugging the value of wavelength and frequency in the above formula we get :
Speed =
Speed = 340

The hydrogen deficiency index( HDI) of strigol is = 10
<h3>How to calculate HDI:</h3>The hydrogen deficiency index is used to measure the number of degree of unsaturation of an organic compound.
Strigol is an example of an organic compound because it contains carbons and hydrogen.
To calculate the HDI using the molecular formula given (C19H20O6) the formula for HDI is used which is:
where C = number of carbon atoms = 19
n= number of nitrogen atoms = 0
h= number of hydrogen atoms = 20
X = number of halogen atoms = 0
Note that oxygen was not considered because it forms two bonds and has no impact.
There for HDI =
HDI=
HDI =
HDI = 10
Therefore, the hydrogen deficiency index of strigol is = 10
