The answer of the following question of digital clocks are: (a) clock b and a is 92:38, (b) clock c and clock A is 92:38, (c) when clock a reads 380 s, clock b reads 285.3 s, (d) when clock c reads 11 s, the clock b reads 8.5s.
What is digital clocks?
Digital clocks are electronic clocks that use a digital display to show the time. They often use an LED or LCD display to show the time in a digital format, usually in hours and minutes. Digital clocks are a more accurate and convenient way for people to keep track of time.
(a) Clock B: 600 s apart on clock B will be about 484.4 s apart, as the ratio between clock B and clock A is 25:38.
(b) Clock C: 600 s apart on clock C will be about 828.3 s apart, as the ratio between clock C and clock A is 92:38.
(c) Clock B: When clock A reads 380 s, clock B will read about 285.3 s. In the earliest occasion, clock B reads 25s and clock A reads 38s. This gives us a ratio of 25:38. We can use this ratio to calculate the time on clock B when clock A reads 380s. 380s × (25/38) = 285.3 s.
(d) Clock B: When clock C reads 11s, clock B will read about 8.5s. In the earliest occasion, clock B reads 25s and clock C reads 92s. This gives us a ratio of 25:92. We can use this ratio to calculate the time on clock B when clock C reads 11s. 11s × (25/92) = 8.5s.

you are troubleshooting a computer system and want to review some of the motherboard configuration settings. where is most of this data stored?
The CMOS chip contains the BIOS settings (which is kept powered up via the battery on the motherboard). Because of this, whenever you remove and then replace the battery, the BIOS is reset.
Initially, the PC motherboard's ROM chip served as the location for the BIOS firmware. The BIOS data is saved on flash memory in more recent computers so that it may be changed without removing the chip from the motherboard. These settings were saved in nonvolatile RAM by the BIOS the last time the computer booted properly. The CMOS is where the BIOS saves the date, time, and system configuration information it needs to start the computer. The BIOS is the programme that initiates this process. The computer is under the supervision of a little software called the BIOS from the moment it turns on until the operating system takes over.

which feature of oop illustrated the code reusability? group of answer choices polymorphism inheritance encapsulation
Code reuse is indicated via inheritance. Abstraction and encapsulation are used to disguise or combine data into a single piece.
As a key component of Object-Oriented Programming (OOP), code reuse is made possible by inheritance, polymorphism, and information hiding. By using inheritance, an object can be expanded and its child object's code from the parent object can be reused or overloaded. Encapsulation is an OOPS mechanism that unifies multiple data members and member functions into a single unit by implementing the member functions on those multiple data members. This method gives the user the opportunity to reuse it. While the OOP paradigm uses dynamic binding, encapsulation, and abstraction for various purposes.

old cassette tape sound recordings often would have extra noise on the tape. a new digital computer file only contains the recorded sound. which statement is the best conclusion that can be drawn from this information?
The best conclusion that can be drawn from this information is that digital computer files produce a higher quality sound recording compared to cassette tapes due to the lack of extra noise on the recording.
How sound recording works in cassette tapes?
Sound recording on cassette tapes works by magnetically encoding the sound onto the tape. The tape is made of a magnetic material, and it passes over a recording head, which generates a magnetic field that aligns the magnetic particles on the tape.
The alignment of the particles represents the sound being recorded. When the tape is played back, the tape passes over a playback head, which generates an electrical current based on the alignment of the magnetic particles on the tape, which then is converted into sound by an amplifier and speakers.
