A yellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. A red ball with a mass of 3 kg is rolling across the same floor at 3 m/s. Which ball has greater kinetic energy, and why? The yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground.
The red ball has greater kinetic energy, because it has a greater mass.
The yellow ball has greater kinetic energy, because it is rolling at a greater speed.
The red ball has greater kinetic energy, because it is releasing more thermal energy.

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.
