Multiple choice general knowledge science & technology

There is a friction force of 10 Newtons between a box and a table top. In order to move the box at a constant velocity, you would have to supply a force of:

  1. 10 Netwons

  2. > 10 Newtons

  3. < 10 Newtons

  4. Nonsense! No force is required to move the box
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To move at constant velocity (zero acceleration), the applied force must exactly balance the friction force. Since friction = 10 N, the applied force must also be 10 N to achieve net force = 0 (Newton's First Law).

If the force of gravity suddenly stopped acting on the planets, they would….

  1. Fly straight away from the Sun

  2. Continue to orbit the Sun

  3. Spiral slowly towards the Sun

  4. Move in a straight line tangent to their orbit
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Planets orbit the Sun due to gravity providing the centripetal force. If gravity disappeared, Newton's First Law states they would continue moving in a straight line (tangent to their orbit at that instant) with whatever velocity they had.

Why was the first Intel Celeron processor not as popular as expected?

  1. Had errors

  2. No level 2 cache

  3. Caused errors

  4. Caused Excess heat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The first Celeron processors lacked L2 cache memory, which significantly reduced performance compared to Pentium II processors. This made them slower despite running at similar clock speeds. Later Celeron models added L2 cache and became much more popular.

Multiple choice general knowledge science & technology

The windows registry consists of which two files?

  1. autoexec.bat and config.sys

  2. user.dat and win.ini

  3. user.dat and system.dat

  4. win.reg and user.dat
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Windows Registry stored configuration data in two hidden files: USER.DAT (for user-specific settings) and SYSTEM.DAT (for system-wide settings). These files were located in the Windows directory. Autoexec.bat and config.sys were DOS-era files, while win.ini was a Windows 3.x configuration file.

Multiple choice general knowledge science & technology

Unix is short for what?

  1. UNIt eXchange

  2. UNIform eXchange

  3. UNIt X

  4. It is not an acronym
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Unix is NOT an acronym - it was named as a pun on Multics (from which it was developed). The name has no actual meaning as an abbreviation. Options A, B, and C incorrectly try to expand Unix as if it were an acronym.

Multiple choice general knowledge science & technology

Microsoft Windows XP is an upcoming operating system, what is XP short for?

  1. Whistler

  2. eXtra Powerful

  3. eXPerienced

  4. It is not an acronym
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Windows XP was codenamed 'Whistler' during development, named after the ski resort in British Columbia where the development team held a retreat. The letters 'XP' do not stand for eXtra Powerful or eXPerienced - they were chosen to sound modern and tech-forward, not as an acronym.

Multiple choice general knowledge science & technology

The partly lighted area of a shadow on the periphery of the totally shaded portion is called the _______

  1. Umbra

  2. penumbra

  3. eclipse

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The penumbra is the partially shaded region at the edge of a shadow where only part of the light source is blocked. The umbra is the completely dark center where all light is blocked. An eclipse is when one celestial body passes through another's shadow.

Multiple choice general knowledge science & technology

Materials that allow light to pass but through which objects cannot be clearly seen are said to be _______

  1. opaque

  2. transparent

  3. translucent

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Translucent materials allow light to pass through but scatter it, preventing clear visibility of objects. Transparent materials allow clear vision, opaque materials block light completely. Examples include frosted glass, wax paper, and certain plastics.
