Physics occurs all the time but often goes unnoticed. here is your chance to reflect on physics in action. other than the examples used in this lesson, think of a time where you witnessed the conservation of angular momentum. describe the objects that had angular momentum and how angular momentum was conserved. you may also create an example if you cannot recall one in your personal experience.

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m

In what direction does an applied force move an object

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.
