A student constructs a small sailboat. A wind machine is able to blow air at a constant applied force of 5, 10, 15, or 20 newtons. The student places the boat in a large tank filled with water and tests each wind force setting on the machine.
Which wind force will result in the boat having the greatest speed?
5 nertons
10 newtons
15 neurons
20 newtons

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.
