scale reads 810 n. what is the magnitude and
direction of the elevator's acceleration?

a. 0.23 m/s2 up
b. 1.3 m/s2 up
c. 6.5 m/s2 down
d. 11 m/s2 down

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply

Avalue that describes how heavy an object is and is related to the force of gravity is

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.
