What is the escape velocity is km/s from Jupiters exosphere, which begins about 993 km above the surface ? Assume the Gravitational constant is G= 6.67 x10-11m3 kg-1s-2, and that's Jupiter has a mass of 1.8999999999999998e+27kg and a radius of 68.0 x103km
Jupiter is slightly larger than Saturn but its density is about 2 times the density of Saturn. The reason for this density difference is
a. Jupiter's higher mass and gravity compress its interior more
b. Jupiter is more compressed by Sun's gravity
c. Jupiter has larger volume
d. Jupiter has larger proportions of rocks and metal
Calculate the pressure p of the Venus atmosphere (it consists of CO2 at 477oC) at the height of 1 km from the planet surface, where p0=9.3 MPa. The planet mass is 4.9x1024 kg, its radius is 6050 km

Which molecules can Triton retain in its atmosphere? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies.

- What is the density of Jupiter’s moon Europa (see Appendix G for data on moons)?arrow_forwardTitan has a very thick atmosphere of nitrogen gas at a surface pressure (P) of 150 kiloPascals (kg·m/sec2/m2 units). If pressure (P) is force per unit area, then the mass pushing down over 1 square meter of the surface will scale as P/g with g (1.352 m/sec2) being the surface acceleration due to gravity. Considering that the density of solid nitrogen is 1027 kg/m3, calculate the layer thickness of solid nitrogen that would result from freezing the atmosphere by dividing the density of nitrogen into the mass per m2? answer choices 108 meters 10.08 meters 1.08 kilometers 1.08 metersarrow_forwardWhich of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system?

- NASA Scientists want to measure the current distance between two of Jupiter's Moons, Ganymede and Europa. They set up a laser on the surface of Ganymede, shine it at a mirror on the surface of Europa and measure how long it takes for the laser light to return to a detector on the surface of Ganymede. They calculated the current distance between the two moons to be 787 million meters. How long did it take the light to make it to Europa and back? *Give answers to at least three significant figures.
