Compare these atmospheric pressure with Mars and estimate how high you'd need to go in Earth's atmosphere to be at the same pressure as the surface of Mars?
The given information is in the attachment.
What would Earth's surface gravity and escape speed be if
the entire planet had a density equal to that of the crust (3000
kg/m³, say)?
(Ch 13 HW
Exercise 13.16 - Enhanced - with Feedback
Jupiter's moon lo has active volcanoes (in fact, it is the most volcanically active body in the
solar system) that eject material as high as 500 km (or even higher) above the surface. lo
has a mass of 8.93 × 1022 kg and a radius of 1821 km
Part A
How high would this material go on earth if it were ejected with the same speed as on lo? (RE = 6370 km, mg = 5.96 × 1024 kg)
Express your answer with the appropriate units.
