Aperson on a diet loses 1.6 kg in a week. how many micrograms/second (µg/s) are lost?

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.

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

Suppose an object in free fall is dropped from a building. its starting velocity is o m/s. what is the speed (in m/s) of the object falling after 2 seconds?
