Nasa’s mission juno is currently orbiting jupiter. the most recent full orbit juno made (as measured between the times of closest approaches to jupiter) started on july 21, 2019 and ended on september 12, 2019. you can assume that both passages happened at the same time, e. g. at 6 am. what is the semi-major axis of the orbit of juno around jupiter, expressed in kilometers?

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
