What is true for two pieces of iron at the same temperature? a: the total kinetic energy of their particles is equal. b: heat flows from the object with higher potential energy to the object with lower potential energy. c: heat flows from the larger object to the smaller object. d: the average kinetic energy of their particles is the same

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.
