Which best summarizes a concept related to the work-energy theorem? when work is positive, the environment does work on an object. when work is negative, the environment does work on an object. when work is positive, the kinetic energy in a system remains constant. when work is negative, the kinetic energy in a system remains constant.

Find the mass by adding the numbers from the three sliders

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.
