A spring is used as part of a lift system and follows Hooke's law. If the spring is displaced 85 cm when the force acting on it is 12500 N what is the displacement
when the force increases to 15500 N?

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.
