Asatellite s travels in a circular orbit around the earth. a rocket is located at the apogee of its elliptical orbit for which  = 0.58. (a) determine the sudden change in speed that must occur at a so that the rocket can enter the satellite’s orbit while in free flight along the blue elliptical trajectory. (b) when it arrives at b, determine the sudden adjustment in speed that must be given to the rocket in order to maintain the circular orbit.

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?

Which radioisotope is used in dating geological formations?

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.
