You are looking up at the Moon, which is 3.8 × 108 m away from Earth. It is nighttime, and your pupils have opened to a diameter of 8 mm. Assume that the light has a wavelength of 600 nm. a. If you're looking at two objects on the Moon's surface, how far apart must they be for you to be able to resolve them? Assume that the light from the Moon has a wavelength of 600 nm. (1 point)

b. When you're in the dark for a long time, your pupils open wider. Why would letting your eyes adjust to the dark help you resolve objects on the Moon? (1 point)

The following statements are about the electroscope. select all that are true. if an electroscope were given a positive charge beforehand, the leaves would move closer together if a positively charged object were brought near. when a properly prepared electroscope is used to determine the type of charge on an object, the total charge on the electroscope changes when the charged object is brought near (but not touching) the electroscope. depending on how the electroscope is prepared beforehand, the leaves can either move together or move apart when negative charge is brought near. an electroscope must first be given a known type of charge before it can be used to identify the types of charges on objects brought near it. when properly prepared, the leaves on an electroscope will always move further apart when negative charge is brought near. the leaves of an electroscope will move apart if it is given either a positive or a negative charge.
