(A) The pressure at 10 m below the surface of the ocean is about 2.00Γ10^5 Pa. Which of the following statements is true? a) The weight of a column of seawater 1 m^2 in cross-section and 10 m high is about 2.00Γ10^5 N. b) The weight of a column of seawater 1 m^2 in cross-section and 10 m high plus the weight of a column of air with the same cross-section extending up to the top of the atmosphere is about 2.00Γ10^5 N. c) The weight of 1 m3 of seawater at 10 m below the surface of the ocean is about 2.00Γ10^5 N. d) The density of seawater is about 2.00Γ10^5 times the density of air at sea level. (B) Now consider the pressure 20 below the surface of the ocean. Which of the following statements is true? a) The pressure is twice that at a depth of 10 m. b) The pressure is the same as that at a depth of 10 m. c) The pressure is equal to that at a depth of 10 m plus the weight per 1 m^2 cross-sectional area of a column of seawater 10 m high. d) The pressure is equal to the weight per 1 m^2 cross-sectional area of a column of seawater 20 m high.

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.
