Unformatted text preview: -8 m. What is the frequency and energy of this wavelength? 3) What is the difference in LGP between our observatory of 0.4 meters and the Keck Observatory of 10 meters? And what would the resolution be for the wavelength above in our observatory? For the Keck? Which telescope is better for the viewing this wavelength? 4) Jupiter takes 687.0 days to orbit the sun, what is the angular velocity in degrees per day? per hour? 5) A 70 kg man is standing on the Earth at a height of 2 meters. What is the gravitational force between the man and Earth (Remember a=g=9.8m/s 2 )? How does this compare with the gravitational force between the man and Jupiter (Hint R= the radius of Jupiter)?...
