How long does it take (in seconds) a 80,000 W motor to do 3,000,000 J of work?

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.

Imagine that the rightward current flows in the rod for a short time. as a result, what will the net charge on the right and left ends of the rod become? left end negative and right end positive left end negative and right end negative left end negative and right end nearly neutral left end nearly neutral and right end positive both ends nearly neutral

You are waiting in line to use the diving board at your local pool. while watching people dive into the pool from the board, you realize that using a diving board to spring into the air before a dive is good example newton's third law of motion. explain how a diving board illustrated newton's law of motion
