Aping pong ball with a dent in it can be put into a pan of boiling water. after a short amount of time, the dent will pop out. determine the best reason for this occurrence. a) the ping pong ball plastic heats up and expands. b) the number of gas particles inside the ping pong ball increases causing more pressure. c) the gas particles inside speed up due to heat and cause an increase in pressure within the ball. d) gas particles inside collide with each other less and with the ball more causing the dent to pop out.

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.
