Apeacock mantis shrimp smashes its prey with a hammer-like appendage by storing energy in a springlike section of exoskeleton on its appendage. the spring has a force constant of 5.9×104n/m.
part a if the spring stores 0.0106 j of energy, over what distance must the shrimp compress it? express your answer to two significant figures and include appropriate units.
part b
what power does the shrimp generate if it unleashes the energy in 0.0016 s? (the power per mass of the shrimp appendage is more than 20 times greater than that generated by muscle alone, showcasing the shrimp's ability to harness the potential energy of its spring.)
express your answer to two significant figures and include appropriate units.

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.
