11. A 5-kilogram block is being pushed across a horizontal table by an 22 newton force. If the coefficient of kinetic friction between the block and the table is 0.15, find the acceleration of the block.

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in the collision? explain why or why not

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.

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
