An astronomer wants to observe at a particular wavelength using one of the telescopes listed. Arrange these telescopes from worst to best angular resolution based on the diffraction limit. Worst resolution to Best resolution.1. personal 8-inch telescope 2. Mayall 4-Meter Telescope at Kitt Peak National Observatory 3. 2.1-meter Otto Struve Telescope at McDonald Observatory 4. Nickel 1-meter telescope on Mt. Hamilton 5. 10.4-meter Gran Telescopio Canarias

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The answer would be a) -80of
