8. A 10-inch beam is in the path of a conduit run from a junction box which is located 38 inches from the beam. The beam is to be bypassed by a 30-degree offset with the second offset bend occuring at the corner of the beam. At what distances from the outlet box will the two bends be marked on a length of 1-inch EMT?

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.
