If city is located in 2.8° north latitude and 46.0° east longitude. From there, you want to fly to a city in 7° north latitude and 52° east longitude. How much is the
arc length of the big circle at 11000 m when the earth's radius is 6370 km?
The arc length is 14223 km.
Give your answer rounded to one kilmetre.
Your last answer was interpreted as follows: 14223
XAnswer is incorrect.
Keep centre of Earth as origin and define vectors to cities. Try again.
Right Ascension and Declination is a coordinate system for objects in the sky, and is analogous to longitude and latitude coordinates, respectively, for objects on Earth. Right ascension (RA) coordinates are given in hours (h), minutes (m), and seconds (s). Declination (DEC) coordinates are given in degrees (°), arcminutes ('), and arcseconds (").
Sirius is the brightest star in the night sky. Its RA and DEC coordinates are 6h 45 m 7.96 s and -16° 44' 78.6".
Using unit conversion, find the RA coordinate only in hours and round the coordinate to 5 significant figures.
What is the number of nautical miles between place A (60°N, 75°W) and place B (70°S, 75°W)?
