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.

Which of the following is true of meridians? (15.2) (a) They run east and west. (b) They are halves of great circles. (c) They are great circles. (d) All of these are true.
To find the acceleration from equation (a=v^2/r), the velocity of an object traveling in a circle is the distance traveled (i.e. the circumference, which is 2?r) divided by the travel time (i.e. the period T). The Moon’s sidereal period is 27.32 days. Convert this period into seconds. Complete Table 1 for the Moon to find its orbital period in seconds, its average velocity in meters per second and its acceleration in meters per second^2 where Orbital radius (m) = 3.84 x 10^8.

An air traffic controller notices two signals from two planes on the radar monitor. One plane is at altitude 1104 m and a 11.6-km horizontal distance to the tower in a direction 30.6° south of west. The second plane is at altitude of 5420 m and its horizontal distance is 8.8 km directed 23.8° south of west. What is the distance between these planes in kilometers?
