On The First Day Of Class You Were Invited To Imagine A Scale Model Of The Solar System Where We Divided All The Real W 1 (46.11 KiB) Viewed 12 times

On the first day of class, you were invited to imagine a scale model of the solar system where we divided all the real world distances by approximately 8.7x10. That scaling shrinks the Sun to about 0.16 m or 16cm across, more or less the size of a large grapefruit, and it shrinks the Earth-Sun distance to approximately 17 m. What would the angular diameter of that 16cm grapefruit be as seen from 17 m away? How does this compare with the actual Sun's angular diameter (about half a degree) as seen from Earth? Hint: you can do this by actually plugging the numbers into the formula, but you might also be able to find a shortcut. If you use a shortcut, briefly explain your reasoning. (1pt)
