Chapter 22, Problem 5P
Calculate the mass of Callisto using a value for its density of 1.8 g/cm3. Convert your answer to units of kg, and compare to the mass of Ganymede given in Problem 5. (Notes: Density is mass divided by volume, and the volume of a sphere is
4. What is the escape velocity from the surface of Ganymede? Ganymede’s mass is 1.5 × 1023 kg and its radius is 2.6 × 103 km. (Hint: Use the formula for escape velocity, Eq. 5-1b. The formula requires input quantities in kg and m.)

Assuming all other variables were earth based besides atmospheric pressure, calculate the temperature at which water would boil at sea level on Titan versus Earth? And explain why using molecular concepts. Consider the pressure of Earth’s atmosphere at sea level to be 1 atm and the pressure of Titan’s atmosphere at sea level to be 1.45 atm.

A classmate claims that if Jupiter’s Galilean moons were all the same distance from Jupiter, they would all experience the same amount of gravitational force. Using what you have learned and the evidence from the data table how would you respond to his claim?
(a) His claim is incorrect; if the moons were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Ganymede because it has the greatest mass
(b) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Europa; because it has the smallest mass
(c) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity from Jupiter would be experienced equally by all four moons.
(d) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Ganymede because it is the largest moon

The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth are at the closest point to one another in their orbits.) How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees? Part 1 of 4 We first need to determine how fast the planet is moving across the sky. If we know the period and the distance between the Sun and the planet we can calculate the velocity using: 2ar which will tell us how many kilometers the planet travels in a day if we convert the period into days. days = (P years' |days/year Pdays days Submit Skip (you cannot come back)arrow_forwardThe ratio of charon to pluto's roche limit? or How close is Charon to Pluto's Roche limit? please solve accurate and exactarrow_forward

- Upload a PDF document that shows your work and solution. - Consider a moon of Uranus if Uranus is currently a distance of 2.08 billion km from Earth, then what diameter telescope would you need (use telescope-resolution formula = 1.22, where D is the telescope diameter) in order to clearly resolve the moon Titania in orbit around Uranus if the 47² )3 to relate moon has a period of orbit of T = 8.71 days? (use Kepler's 3rd Law T² = (GMrave T2 moon's period T to moon's orbital radius, r) The telescope only needs to resolve the small dot of the moon as distinct from the circle of light which is Uranus, so the orbital resolution is the angular size of the diameter of orbit of Miranda (use the arc-length formula 0 = 2 where d is the distance from Earth to Uranus).
