If you went to a planet with an acceleration due to gravity of 20 m/s^2 and twirled a bucket of water, what happens to the angular speed you need to twirl the bucket to keep the water in?

a - angular speed increases
b - angular speed decreases
c - angular speed stays the same

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.

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

What is the relationship between the direction of motion of the balloon and the wind currents
