Textbook Question
Chapter 13, Problem 27E
Make a similar estimate for the mass of the Kuiper belt. The three largest objects are Pluto, Eris, and Makemake (each roughly 2000 km). In addition, assume there are eight objects (including Haumea, Orcus, Quaoar, Ixion, Varuna, and Charon, and objects that have not been named yet) with diameters of about 1000 km. Assume that all objects have Pluto’s density of 2 g/cm3. Calculate twice the mass of the largest 13 objects and compare it to the mass of the main asteroid belt.

There is one part to this question. I need to know the km/s. Thank you!
What is the observed angular speed of
Neptune, along the ecliptic of Earth, when it is
at opposition, in units of arc minutes / day?
Presume the orbits are circular. Earth has
orbital speeds of 30km/s and Neptune has
5.43km/s, Neptune here has orbital radius
30.1 AU. Now looking at Uranus for the same
condition, in what direction along the ecliptic
will it be traveling?
(a) What is the difference between the forces due to Neptune on a 1.0 kg mass located at the near side of Triton and at the far side of Triton? Triton has a mean radius of 1,353 km and a mean orbital radius about
Neptune of 354,800 km. (Enter the magnitude in newtons.)
N
(b) Compare this difference to the difference for Earth due to the Moon, 0.22 x 10- N. (Tidal forces are the cause of volcanic activity on some moons.)

- How was Pluto discovered? Why did it take so long to find it?arrow_forwardPresent theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. So how can we explain the presence of jovian-sized exoplanets closer to their star than Mercury is to our Sun?arrow_forwardThe Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion. Give your answer in km/s with one significant figure.arrow_forward
- 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. DO NOT submit answers in scientific notation. Use symbols for units (i.e. m, s, kg, N)*arrow_forwardThere is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the surface of Europa. One way to do this is to put the lander at the end of a rotating arm in an orbiting earth satellite.arrow_forwardI would like you to compare the thickness of Saturn's rings to objects here on Earth if those rings were scaled down to the size of the objects here on Earth (hint: this means it is a ratio problem). Imagine the rings of Saturn like a DVD or CD here on Earth. The DVD has a diameter of approximately 12 cm, whereas the rings of Saturn have a diameter of approximately 280,000 km. The thickness of a DVD is about 0.6 mm and the thickness of the rings of Saturn at their thickest is approximately 1 km. If we were to scale the diameter of rings of Saturn down to the diameter of a DVD, how does the new thickness of the rings of Saturn compare to the thickness of the DVD? Please provide both the new thickness of Saturn's rings and how many times thicker or thinner they would be than a CD in your answer.arrow_forward
- 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 moonarrow_forward6arrow_forwardThe asteroid Ceres has a mass of 9.39 ✕ 1020 kg and an average radius of about 473 km (4.73 ✕ 102 km).
