Options- A. Field
- B. Factor
- C. Flash
- D. Force
- Correct Answer
- Force
ExplanationThe term EMF, or Electromotive Force, its use now in decline, is attributed to Italian physicist Alessandro Volta (1745-1827). Today we generally use the term "voltage" - can you guess why we call it that? - 1. What will a UPS be used for in a building?

Correct Answer: To provide power to essential equipment
Explanation:
UPS stands for Uninterruptible Power Supply. Examples of equipment that may require a UPS supply are computers, fire detection systems, hospital operating theatre equipment and escape route lighting.
Correct Answer: Resistor
Explanation:
So named because it resists (or inhibits) the flow of current.
Correct Answer: Grameen Bank of Bangladesh
Correct Answer: Samuel Beckett
Correct Answer: Literature and Journalism
Correct Answer: Amplitude modulation
Explanation:
Amplitude modulation was the first type to be used in radio. It works well with HF and morse code.
Correct Answer: Spontaneous emission
Explanation:
Spontaneous emission is what you see with most "glow in the dark" toys. You excite the toy by exposing it to bright light, then the toy glows in the dark by spontaneously emitting photons as the excited atoms relax back down to their normal state.
Correct Answer: Text File
Correct Answer: DeskTop Publishing
Correct Answer: Flash
Explanation:
It's commonly used for MP3 players, computer BIOS code and "thumb" drives. Originally developed in Japan by Toshiba, it has become quite popular for products requiring non-volatile erasable memory. Flash devices have a limited number of erase cycles (typically 10,000 to 1,000,000 cycles) so they're not as good a choice for applications in which the data changes constantly. However, since it has no moving parts (unlike a hard disk) it is an excellent choice for storing the operating code for small personal electronics like PDAs, cell phones, digital cameras, and the data in items like MP3 players.
