Scientists have found ancient rock formations dating to the late proterozoic eon in south america. these ancient rocks can be found from the eastern edge of south america's continental shelf, which extends just off the coast of brazil, to the interior of the continent. this general location is indicated by a green circle on the map below. scientists have also found rock formations made out of the same type of rock and from the very same eon at another location. the location of this second group of rock formations strongly supports the current theory of plate tectonics. where is the second rock formation most likely located?

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
