Move the alligator clips so that you are only using 1 battery (1.5 volts) and observe the light bulbs. Then move the alligator clip so you are using 2 batteries (3 volts), then 3 (4.5 volts), then 4 (6 volts). What happens as you add battery packs

Hey.. ♥️♥️ me in solving this question

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.

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.
