If you are on the top of a mountain and drop an apple, it will fall
to the ground, even though the apple is gravitationally
attracted to you. Why?
Earth is larger and has a much stronger
gravitational pull
b Apples always fall down
Centrifugal forces pull the apple to the Earth and
that is stronger than your gravitational pull
None of these

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.

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)

Which describes increasing the efficiency of energy resource
