- A small cloud in Jupiter's equatorial region is observed to be at 120.80 ° west longitude in a coordinate system that rotates at the same rate as the deep interior of the planet. Another observation made exactly 9.50 Earth hours later finds the cloud at 119.60 ° west longitude. Jupiter's equatorial radius is 71,500 km. What is the observed equatorial wind speed in kilometers per hour?Examine the photos of Jupiter and Saturn in Figure 15. What do you notice about their shape? Referring to Figure 16 how can this peculiar shape be explained?_____ km/s ______ hr

This is primarily due to the presence of _________________ beneath its cloud tops.The asteroid Ceres has a mass of 9.39 x 1020 kg and an average radius of about 473 km (4.73 x 102 km). What is its escape velocity (in m/s)? 2GM (Hints: Use the formula for escape velocity, V. ; remember to convert units to m, kg, and s.) r m/s Could you jump off the asteroid? Yes NoIf you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line at a wavelength of 505 nm, what difference in wavelength (in nm) should you expect between the opposite edges of the rings? (Hints: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity,
- What is the difference in orbital velocity between Saturn's two coorbital satellites if the semimajor axes of their orbits are 151,400 km and 151,500 km?If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in nm) should you expect between the opposite edge of the rings? (Hint: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity and the formula for the Doppler shift.) _______ nmKm/s
