Arocket blasts off and moves away (distance is increasing) from earth. how is the rocket affected by earth's gravitational pull as it moved further away? the pull of gravity on the rocket remains constant the pull of gravity on the rocket increases the pull of gravity on the rocket decreases the pull of gravity on the rocket reverses

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.
