Learning goal: to practice problem-solving strategy 40.1 for quantum mechanics problems. suppose a particle of mass m is confined to a one-dimensional box of length l. we can model this as an infinite square well in which the particle's potential energy inside the box is zero and the potential energy outside is infinite. for a particle in its first excited state, what is the probability prob(center20%) of finding the particle within the center 20% of the box?

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.
