Ten narrow slits are equally spaced 2.00 mm apart and illuminated with green light of wavelength 511 nm. the width of bright fringes can be calculated as the separation between the two adjacent dark fringes on either side. find the angular widths (in rad) of the third- and fifth-order bright fringes. third-order bright fringe rad fifth-order bright fringe rad

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.
