An AC power supply has an "rms" voltage of 120 V and oscillates at 60 Hz. This power supply is connected to a lightbulb, resulting in an average power output of 60 W. The same power supply is then connected to a capacitor instead of a resistor. The capacitor has a capacitance of 11 mF. Find the capacitive reactance of the circuit. Find the maximum current through the power supply while it is connected to the capacitor.

Based on the concept of the wave-like nature of light, huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. a) deflection b) interference c) refraction d) resonance

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant

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.
