The Gaia spacecraft's telescope has an accuracy of 0.00005 arcsec. The human eye, meanwhile can only resolve about 1 arcminute. How many times better is the resolution of the Gaia spacecraft compared to the human eye?

The temperature of each hot plate is indicated by a shade of gray such that the lighter the shade of gray, the higher the temperature of the hot plate. D E A A. Ranking instructions: Rank the surface area (from largest to smallest) of the hotplates. Ranking Order: Largest 1 2 3 4. Smallest Or, all the hotplates have the same surface area. (indicate with a check mark) Carefully explain your reasoning for ranking this way: B. Ranking instructions: Rank the temperature (from hottest to coldest) of the hotplates. Coldest Ranking Order: Hottest 1 Or, all the hotplates have the same temperature (indicate with a…

Geostationary satellites cannot be seen in a telescope from Albany because they are always directly over the Equator. True False

For a human eye with a pupil diameter (aperture diameter D) of 0.005 meters, and a focal length of 0.022 meters, there will be a resolution limit due to diffraction at 0.6 microns (10^-6 meters) wavelength. If we space light-sensitive cells on the retina at this spacing, how many retina cells per meter (of retina) are there? cells/meter. Now suppose there are giants which are exactly twice the size of humans in each dimension. So giant eyes have pupils of 0.01 meters, and a focal length of 0.044 meters. How many retina cells per meter should the giants have? cells/meter
