What two devices in a computer should be considered "black boxes," and should never be opened due to risks involving charged cap
NNADVOKAT [17]

The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.

Explanation:

  • Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
  • To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
  • A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.

The options above are the correct answers to the given questions.

Selection sort is a simple comparison-based sorting algorithm.

selection sort. (algorithm) Definition: A sort algorithm that repeatedly searches remaining items to find the least one and moves it to its final location. The run time is Θ(n²), where n is the number of elements. The number of swaps is O(n).

It is this sorting algorithm that will best ne suitable in the given event.
