What is the trend in sizes of the ions n3−, o 2−, f− and why does the trend exist? 1. n 3− > o 2− > f −; the effective nuclear charge is smallest at n3− and the largest at f −. 2. n 3− > o 2− > f −; for an isoelelectronic series, the ionic size decreases as the p + e− ratio decreases. 3. impossible to tell, since ionic radii for different elements cannot be compared; ions can only be compared to the neutral atom. 4. f − > o 2− > n 3−; in an isoelelectronic se-?

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
