1. Conduct research to identify claims made about the effects that certain frequencies of EMR have when absorbed by matter. Find two examples from published sources. Write brief descriptions of your two examples. (5 points) A) What parts of the EM spectrum are being used? Compare them in terms of wavelength, frequency, and energy.

B) What cause-and-effect relationships are being suggested or predicted based on smaller-scale mechanisms in the systems described by the claims?

C) State whether each claim appears to be valid or false. Give a reason to support each of your evaluations.

Sorry i don’t know what to do

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
