When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path?

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.

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?

How is the ideal mechanical advantage of a wheel and axle calculated?
