Answer #1

Low frequency means higher wavelenght.higher wavelenght sound waves need more time to generate and can travell longer distance than high frequency sound waves.attenuation means reduction in the intensity of a wave. low frequency sound is not affected much in space,so it has more power and it can affect a much more area rather than high frequency sound.one cant feel the noise of low frequency infrasonic sound but it does feel as a beat in heart.which is a more dangerous condition.so to set the noise as low frequency is not a good idea in accordance to public health.

I have a couple of questions of topics that aren't 100% clear to me: How might one use (R)-2-phenylpropanoic acid in a classical resolution scheme to separate a racemic mixture of 2-butanol into enantiomers? Use words and pictures to explain the specific steps you could use. (Hint: Consider the Fischer esterification and its reversibility) Where would you expect EAS to be most favorable on 4-methylcatechol? Explainyour choice completely in terms of steric and electronic effects. Thank you for any explanation...

The data below were obtained to predict the sound frequency to which a person’s ear will respond based upon the length of time a person has been exposed to a high level of noise. Here “length of exposure” is the amount of time in weeks that a person has been living close to a major airport and the “hearing range” is reported in thousand cycles per second. Length of exposure In weeks (Left) Hearing range In thousand cycles per second...

I just need the analysis for the second part why when I have a decrease in net export the answer is not 500X5. I just need good explaining for the analysis. 500X5= 2500 however it didn't decrease by 2500 when I plugged number into the equation, but when I do that when government expenditure increase it works? why? Consumption spending in a country is represented by C = 1800+ 0.8(Y-T ). Planned investment is 900, government purchases G = 0,...
