A stadiuk is filled with 15,811 home-team fans. The home team won all 15,811 fans stand and cheer. Assume that each individual fan produces a sound intensity of 10^-5 W/m^2, as heard feom the ground. What is the total sound intensity level heard on the ground? (in terms of dB)

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.
