General Science & Technology Quiz

The human body uses approximately 200 muscles to take a single step. This complex coordination involves muscles in the feet, calves, thighs, hips, and core, all working together to maintain balance and propel forward motion. This surprising fact highlights how intricate human locomotion actually is.

The lunula is the white, crescent-shaped area visible at the base of your fingernail. It's part of the nail matrix where nail growth begins. 'Habis', 'Salsi', and 'Beled' are not anatomical terms related to fingernails.

Women's hearts typically beat faster than men's hearts, averaging around 78 beats per minute compared to 72 bpm for men. This is primarily due to women's generally smaller heart size, which requires more frequent contractions to pump the same amount of blood.

India has the world's largest deposits of mica, particularly in Rajasthan and Andhra Pradesh. India accounts for about 60% of global mica production. Gold, copper, and other minerals are not India's largest in global terms.

John Napier, a Scottish mathematician, invented logarithms in 1614 and published logarithm tables. This revolutionized mathematical calculations. Options B, C, and D are not historical mathematicians associated with this invention.

Joule is the SI unit of energy, defined as the work done by a force of one newton moving through one meter. Temperature is measured in kelvin, pressure in pascal, and heat (as energy transfer) also in joules.

The Heavy Water Board (HWB), responsible for production of heavy water for nuclear reactors, is headquartered in Mumbai. It operates under the Department of Atomic Energy.

Bharat Electronics Limited (BEL), headquartered in Bengaluru, is a premier PSU manufacturing communication and radar equipment for the Indian armed forces and paramilitary organizations. GSL makes ships, BDL makes missiles.

Electrons are subatomic particles with negligible mass (~1/1836 of a proton). Molecules are composed of atoms and are vastly larger than electrons. A single molecule can contain billions of electrons.

Electrons are subatomic particles with negligible mass compared to atoms, while molecules consist of two or more atoms bonded together. An individual electron is far smaller than even the simplest molecule, making the statement false.

Mark Zuckerberg founded Facebook in 2004 while he was a student at Harvard University, initially launching it as a social network for college students. The other inventors listed created different technologies: Karl Benz invented the automobile, Albert Einstein developed the theory of relativity, and Laszlo Biro invented the ballpoint pen.
