Question 46 [1 point) How much better resolution would a 60 mm objective lens have than your eye's 6 mm exit pupil? If). 6 times .jf ). 10 times (\"a 60 times \\___/ (""3 16 times \\___/ Question 47 (1 point) The new Moon happens about once a month, and is often described as happening when the Moon passes between the Sun and the Earth. Why isn't there an eclipse during every new Moon? ,f'X, The Moon can only block the Sun when it is furthest away from Earth, and most .\\___/. new Moons happen when the Moon is at another place on its orbit. (\"\"3 The apparent size of the Moon is only occasionally large enough to block the Sun \\ / (""1 The Moon is not actually directly between the Earth and the Sun during the new ' Moon because its orbit is tilted relative to the celestial equator ("'3 The Moon is not actually directly between the Earth and the Sun during the new \\. .. Moon because its orbit is tilted relative to the ecliptic plane. Question 48 (1 point) There are no radio telescopes in space because: (A) no one has built an antenna large enough to reach astronomical objects yet. (\":1 you need an array, like the VLA, to detect ANY radio radiation, so it is just not realistic to put an entire array in space. / .; 3:; radio telescopes are too fragile and expensive to make to put into space. \\ ("NI radio waves penetrate Earth's atmosphere so there is no need to put one in .\\___/. space. Question 49 [1 point) Which statement gives the relationship between the waves in the electric and magnetic fields in an electromagnetic wave? J"_' I, :3 They are in phase but perpendicular to each other in space. \\ J"_' I, :3 They re in phase and parallel with each other in space. \\ ("31 They are 90 degrees out of phase but parallel in space \\___/ ("3' They are 180 degrees out of phase and random in their inclinations to each \\___/ other Question 50 (1 point) Jupiter lies about 5 A.U. from the Sun, so at its distance: If :1. the Sun's gravity is so weak that ultimately Jupiter will escape the solar system {Pt} the Sun's gravity is just as strong as it is here at Earth 2\"- n. the Sun's gravity must be five times stronger to hold massive Jupiter in orbit \\ 2 .. the Sun's gravity is 25 times weaker than its pull on the Earth. \\
