Nuclear fusion, the energy source of the sun, hydrogen bombs, and fusion reactors, occurs much more readily when the average kinetic energy of the atoms is high-that is, at high temperatures. suppose you want the atoms in your fusion experiment to have average kinetic energies of 6.40×10–14 j. what temperature is needed?

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.
