Change the time flow rate to 1 day (solar day). note the position of the moon and the background stars and click the step time forward button to advance time by 1 solar day. then change the time flow rate to 1 sidereal d. (sidereal day) and watch the moon and stars in the view when you click the step time forward button again, this time to advance time by 1 sidereal day. repeat these steps to decide which of the following statements is not correct. a in 1 sidereal day, the background stars do not appear to move but the moon does. b in a 1 day time step, the background stars and the moon both move. c looking at the time display, a sidereal day is shorter than a normal 'solar' day by about 4 minutes. d in 1 day, the stars and the moon both appear to move in the same direction.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
