In the Group Work, once we have calculated (and experimentally determined) our fundamental frequency for our string, how do we find the higher resonant frequencies, or harmonics?

We merely raise the fundamental frequency by the power of the harmonic number: The second harmonic equals the fundamental squared, and so on.

We merely divide the fundamental frequency by the harmonic number: The second harmonic equals 1/2 times the fundamental, and so on.

We merely multiply the fundamental frequency by the harmonic number: The second harmonic equals 2 times the fundamental, and so on.

We merely multiply the fundamental frequency by the log of the harmonic number: The second harmonic equals the fundamental times log 2, and so on.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this

the ima (higher than 1m) will be greater than the ima with the height of 1m.
