Astudent bikes to school by traveling first dn = 1.10miles north, then dw = 0.400miles west, and finally ds = 0.100miles south.
if a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover?
you will now find the same quantity algebraically, without the need to use much geometry. take the north direction as the positive y direction and east as positive x. the origin is still where the student starts biking.
let dā n be the displacement vector corresponding to the first leg of the student's trip. express dā n in component form.

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.
