7. Students were presented with the five cards below and asked to put them in order from 1940 to present day. W х Project Mercury Perseverance Mission International Space Station . Put a man into orbit around Earth • Land a rover on Mars and collect soll samples Space research lab that orbits Earth with 6 crew members Y Z Proiect Gemini Project Apollo • A crew of two that studied how being in space affects humans First humans to land on the moon Which of the following timelines accurately describe the history of space exploration?​

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.
