Having trouble with these questions! Please help
a. Neptune's Great Dark Spot was 10,000 km in diameter and rotated in 17 days. What was the wind speed at the edge of this storm in km/hr? (For comparison, wind speeds on Earth are typically less than 100 km/hr).
b. Jupiter's Great Red Spot is 1.4x105 km in diameter and has wind speeds up to 640 km/h. How long does it take the outer edge to rotate once (in days)?
2. The average distance of Enceladus from Saturn is 238,000 km; the average distance of Titan from Saturn is 1,222,000 km. How much longer does it take Titan to orbit Saturn compared to Enceladus?
