X-ray diffraction is used to study the structure of crystallized proteins, nucleic acids, and other biological macromolecules. it was actually the technique used to study the structure of dna in the early 1950s. x-rays of wavelength 0.17 nm are to used to study the structure of a protein. one of the maxima in intensity is located at 0.8 rad from the crystal planes responsible for this maximum. part awhich wavelength of x-ray listed below would give you a maximum at the same location? a. 26nmb. 43nmc. 34nmd. 60nm

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.
