6. The processing speed of a computer refers to the number of binary operations it can perform in a second. Thus, the processing speed is actually a frequency. If the processor of a personal computer operates at 1.80
GHz (1 GHz = 109Hz ), how much time is required for one processing cycle?

With i really need the correct answer!

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

In a hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. how many unique charge-pairs are there (without double counting)?
