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 European Space Agency launched a probe called Rosetta in March 2004. In August 2014, Rosetta reached its destination: a comet called 67P/Churyumov-Gerasimenko. Rosetta is the first spacecraft to rendezvous with a comet, and plans to orbit the comet. It contained a lander craft, called Philae.
The Philae lander has several scientific instruments onboard, used to study the comet. ALICE is an ultraviolet imaging spectrograph, used to search for noble gases in the comet core. The ALICE instrument uses potassium bromide as one of the compounds in the analysis of noble gases. Potassium bromide has a specific gravity of
2.74.
Assume the lander has a liquid sample of potassium bromide onboard that fills a
1.49-gallon
[gal] container. What is the mass of the potassium bromide sample in the container, in units of kilograms [kg]?

- What is the difference in the orbital velocities of the two shepherd satellites of Uranus, Cordelia and Ophelia, which have orbital radii of 49,800 km and 53,800 km, respectively? (Hint: Use the formula for circular velocity, Eq. 5-1a. The formula requires input quantities in kg and m.)arrow_forwardOn February 7, 1999, NASA launched a spacecraft with the ambitious mission of making a close encounter with a comet, collecting samples from its tail, and returning the samples to Earth for analysis. This spacecraft, appropriately named Stardust, took almost five years to rendezvous with its objective-comet Wild 2 (pronounced "Vilt 2")-and another two years to return its samples. The reason for the long round trip is that the spacecraft had to make three orbits around the Sun, and also an Earth Gravity Assist (EGA) flyby, to increase its speed enough to put it in an orbit appropriate for the encounter.When Stardust finally reached comet Wild 2 on January 2, 2004, it flew within 147 miles of the comet's nucleus, snapping pictures and collecting tiny specks of dust in the glistening coma. The approach speed between the spacecraft and the comet at the encounter was a relatively "slow" 6200 m/s, so that dust particles could be collected safely without destroying the vehicle.

For example if a satellite is in a geosynchronous orbit with a “delta v” of 2km/s, could I use the 2km/s to calculate the radius of orbit?

Use the small-angle formula to find the angular diameter of Mars when it is closest to Earth. How does that compare with the maximum angular diameter of Jupiter? (Assume circular orbits with radii equal to the average distance from the Sun. Using the following distances from the Sun: Mars is 228 million km, Jupiter is 778 million km, and Earth is 150 million km. The radius of Mars is 3396 km. The radius of Jupiter is 71,492 km.) angular diameter of Mars = ( )seconds of arc angular diameter of Jupiter =( )seconds of arc ratio of angular diameters (Jupiter/Mars) = ( )arrow_forwardTutorial Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth day? 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_forward
