1)if 14 billion years ( the approximate current age of the universe) were compressed to 1 year. then on this scale, how many months was the earth (whose true age is about 4.6 billion years) formed after the universe was born.? 2) suppose you wish to construct a scale model of our solar sysytem. the distance between the earth and the sun is 1 astronomical unit (1 AU = 1.5 x 10 ^8km) and you represent this by 15 km. a- what would the scale model distance of the planet Pluto be? ( Pluto’s distance from the sun is 39.5 AU) b- the earth is about 12800 km in diameter . how large would this be on your scale model? c- the sun’s diameter is about 1.4 x 10^6 km. how large would this be relative to earth? d- the nearest star to us after the sun is alpha centauri @ 4.2 light years away (4.0 x 10^13 km) how far would this be on your scale model?

Answer

25.50
