to the horizontal. a) If Mr. Ramirez has a mass of 100 kg and the coefficient of
sliding friction between him and the hand rail is 0.20, what is the force of friction

Your answer

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.
