- The speed of the solar wind is approximately 400 km/s. How many days does the solar wind take to travel from the Sun to Jupiter? (Notes: 1 AU = 1.5 ✕ 108 km;1 day = 86,400 s.)Storms in the jovian planets' atmospheres are generally much longer lived than storms on Earth. (T/F)This is a simulation of two Neptune-sized masses. Click where the field is zero.
- How does the dynamo effect take place in Neptune?Consider an asteroid that orbits in a relatively circular orbit with a semimajor axis a = 2 au from the Sun. A typical asteroid has an albedo, or reflectivity, A ~ 0.3. At our closest approach to the asteroid, we make a measurement of the flux coming from the asteroid to be F = 3 × 10-15 w m-2. What is the radius of the asteroid in km? Include a labelled diagram along with your calculations.What is the evidence that Juper and Saturn are still cooling?
- Re-order the numbers so the events occur in the correct order, with the oldest event as number 2, and the youngest event as number 13. 2. Now at roughly 100% of present-day mass and the asteroid bombardment over, Earth begins cooling and differentiating. As the outer layer of the Earth cools and solidifies, lighter elements and compounds rise to the surface while the denser ones sink to the core 3. The now differentiated ice, gas, and dust of the solar accretion disc conglomerates together into asteroids from gravity 4. "The Big Whack" A Mars-sized protoplanet we call Theia collides with primitive Earth, adding even more energy and mass 5. The Big Bang 6. As the early atmosphere cools, water vapor is eventually cool enough to condense into liquid water, eventually covering the planet in an ocean 7. The debris from the collision of Earth and Theia produce a ring in orbit. This ring eventually coalesces into the Moon, just as Earth coalesced from the solar accretion disc 8. A nebula…Titan is a moon of Saturn. Titan has wind erosion features. Would you expect Titan to have an atmosphere?(a) Calculate the time necessary for Kepler shear to spread rings with the following parameters over 360° in longitude: Width 1 km, orbit 80 000 km from Saturn. Width 100 km, orbit 80 000 km from Saturn. Width 1 km, orbit 120 000 km from Saturn. Width 2 km, orbit 63 000 km from Neptune. no chat GPT HAND WRITTEN ONLY OTHERWISE WILL LEAVE A DOWNVOTE
- Calculate the escape velocity of Titan.Infrared observations indicate that Saturn gives off 2.8 times the energy it receives from the Sun for a total internal power loss of 2 x 1017 W. Assume that gravitational contraction releases this thermal energy. How much must Saturn shrink per year to account for this output?Explain the light emission by meteorite?
