Science and Technology Fundamentals

VLC Media Player is renowned for supporting virtually all audio/video formats without requiring additional codec packs - it's truly 'plays everything'. WMP (Windows Media Player) has limited codec support, Winamp is audio-focused, and Zoom is video conferencing software.

SpeedFan is a hardware monitoring program that can read temperatures, fan speeds, voltages, and even control fan speeds on compatible hardware. The other options (Temp-Read, Measure temp, TempRecorder) are not recognized monitoring software.

GIMP (GNU Image Manipulation Program) is a free raster graphics editor, similar to Adobe Photoshop. While it's more advanced than MS Paint, it's the correct answer among these options - Gump, Lump, and Limp are fictitious names.

A manometer measures pressure, particularly gas and liquid pressure, using a column of liquid. Saccharimeter measures sugar concentration, ammeter measures electric current, and lactometer measures milk density. The prefix 'mano-' refers to pressure in scientific instruments.

This is a duplicate of question 82539 with formatting differences in the options (a./b./c./d. prefixes). A manometer is the correct instrument for measuring pressure. The answer is identical to the previous question.

A light year is the distance light travels in one year, approximately 9.46 trillion kilometers. It is a unit of distance used in astronomy, not related to energy, speed, or intensity.

Joule is the SI unit of energy or work. It measures the amount of energy transferred when a force of one newton acts over a distance of one meter.

A seismograph detects and records seismic waves produced by earthquakes. Barometers measure air pressure, hydrometers measure liquid density, and polygraphs are used for lie detection.

The Celsius and Fahrenheit temperature scales intersect at -40 degrees, meaning -40°C equals -40°F. This is the only temperature where both scales show the same numerical value.

Nicolaus Copernicus formulated the heliocentric model in the 16th century, proposing that the Earth and other planets revolve around the Sun. This challenged the prevailing geocentric view.

Ole Rømer first demonstrated that light has a finite speed in 1676 by observing Jupiter's moon Io. Einstein developed relativity theory, Newton formulated laws of motion, and Galileo studied motion but didn't measure light speed.

Albert Einstein formulated the mass-energy equivalence principle E=mc² in 1905, showing that mass and energy are interchangeable. Planck studied quantum theory, Dalton developed atomic theory, and Rutherford discovered the atomic nucleus.

Oparin proposed the theory of chemical evolution, suggesting life arose from gradual chemical reactions in Earth's early atmosphere (the Oparin-Haldane hypothesis). Darwin focused on natural selection and evolution by natural means, Lamarck on inheritance of acquired traits, and Haeckel on embryology and recapitulation theory.

Exobiology (also called astrobiology) is the study of potential life beyond Earth. The prefix 'exo-' means 'outer' or 'outside,' referring to extraterrestrial environments. The other options are not standard biological terms.

Faraday is incorrectly paired with gas diffusion - he is famous for electromagnetic induction, electrolysis laws, and discoveries in electricity and magnetism. Graham is actually known for gas diffusion. All other pairs are correctly matched: Roentgen discovered X-rays, Newton formulated gravitation laws, and Pasteur founded bacteriology.

Paper is measured in reams (typically 500 sheets) and caliper (thickness measurement). This standard industry practice allows for consistent paper quantity and thickness specifications in printing and manufacturing.
