Question
lo is a volcanically active moon of Jupiter (volcanic plume pictured above). Use the following information to answer the questions below. lo Data Distance from Jupiter: 4.22 x 103 km Diameter: 3640 km i) (Multiple Choice) Which of the following calculations would give me the distance of lo to Jupiter in AU? 93 x 106 miles 0.6214 mi a (4.22 x 105 km) x 1 km km b) (4.22 x 105 km) x 93 x 106 miles x 0.6214 mi 0.6214 mi c) (4.22 x 105 km) x 93 x 106 miles 1 km d) (4.22 x 105 93 x 106 miles 1 km km) x 1 AU 0.6214 miExplanation / Answer
i) The correct choice is C.
1 kilometer = 0.6214 mile
1 Au = 93 x 106
Therefore, 4.22 x 105 km = 4.22 x 105 x 0.6214 mile
= 4.22 x 105 x 0.6214 / (93 x 106) AU
= (4.22 x 105 km) x 1AU / ( 93 x 106 miles) x 0.6214 mi / 1 km
ii) The diameter of Io is 3640 km.
It is scaled to a 8.5 inch bowling ball.
Therefore scaling factor = diameter of bowling ball / diameter of Io
= 8.5 inch / 3640 km
= 8.5 inch / (3640 x 39370.1) inch
= 1 / 16859666

B. North Celestrial Pole
C. Zenith
D. Meridian
E. Celestrial Equator

i) As the latitude of Calgary is 51 degree thus the altitude of polaris at Calgary is 51 degree.
ii) The altitude of celestrial equator is(90- 51) or 39 degrees.
iii) At the equator (latitude 0 degree) observer will see the celestrial equator at zenith.
iv) At the north pole (90 degree north) observer will see the polaris at their zenith.
