The electron is released from rest once it is 1 m from the proton, and travels back towards it. assuming that the proton remains stationary and the electric force is the only force acting, determine the speed of the electron when it has reached a distance of 5×102%% m from the origin.

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.
