Electrons in an electric circuit pass through a resistor. the
wire on either side of the resistor has the same diameter. (a) how
does the drift speed of the electrons before entering the resistor
compare to the speed after leaving the resistor? explain your reasoning.
(b) how does the potential energy for an electron before
entering the resistor compare to the potential energy after leaving
the resistor? explain your reasoning.

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.
