Identify the best explanation for the important role of the liquid outer core, and not the solid mantle, in forming Earth’s magnetic field. A The mantle moves very slowly compared to the outer core. B The outer core moves more quickly than the mantle and has a higher metal content. C The outer core is mostly iron and nickel and the mantle is mostly silicon and oxygen. D The outer core is closer to the center of the planet than the mantle. Identify the best explanation for the important role of the liquid outer core, and not the solid mantle, in forming Earth’s magnetic field.

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.
