The power supply and the Hard drive are the two components that makes loud whining noise when a problem is detected.
<u>Explanation:</u>
- Computers can undergo what's called “coil whine,” which is a high-pitched noise that originates from the computer.
- coil whine is an unacceptable noise emitted by an electronic component vibrating as power runs through an electrical cable.
- It's easy to infer that the noise is an indication of influential computer malfunctioning or that something is cut, disconnected, or about to collapse.
- It is normally caused by an electrical current passing through a power-regulating component like a transformer or inductor, inducing its electrical wiring to vibrate at a shifting frequency.
- Luckily, coil whine is normal behavior.

The class Math include mathematical functions such as sin(), cos(), tan(), abs(), etc
If the given statement is not written, each of the math function will be written as (take for instance, the sin() function):
<em>Math.sin()</em>
<em></em>
But after the statement has been written (it implies that the Math library has been imported into the program) and as such each of the mathematical function can be used directly.
So instead of <em>Math.sin(), </em>you write <em>sin()</em>
