What type of charge will the ion of oxygen have if two electrons are gained by the oxygen atom

The mentor is usually a peer of the individual that acts as a role model and the individual get started in adult life.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

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.
