General Science & Technology Quiz

Intel is the world's largest semiconductor chip manufacturer by revenue, producing microprocessors, chipsets, and other integrated circuits. While Apple designs chips for their products, they don't manufacture at Intel's scale. IBM exited the semiconductor manufacturing business, and Dell doesn't manufacture chips - they use Intel and AMD processors in their computers. The question tests knowledge of the semiconductor industry landscape.

Butterflies, like all insects, have six legs - this is a fundamental characteristic of the insect class. The legs are attached to the thorax (middle body section). Many people mistakenly think butterflies have four legs because the front pair may be reduced or held close to the body. This question tests basic insect anatomy knowledge.

Clitoria (Clitoria ternatea), also known as butterfly pea or Aparajita, produces distinctive blue and white flowers traditionally offered to Lord Shiva in Hindu worship. This flower holds religious significance in Shaivism and is commonly used in Shiva temples across India.

Bougainvillea is a popular hedge plant in Mumbai, prized for its colorful papery bracts (modified leaves) that surround tiny white flowers. The bracts come in vibrant colors - pink, magenta, orange, yellow, white - while the actual flowers are small and tubular. Periwinkle has simple flowers, Quisqualis (Rangoon creeper) has color-changing blooms, and Mimosa is sensitive to touch.

Quisqualis (Rangoon creeper) displays inverted inflorescence with flowers that change color from white to pink to deep red as they mature. This color-changing vine is common in Mumbai and known for its fragrant, drooping flower clusters. Begonia has asymmetrical leaves, Lantana has small multi-colored clusters, and Jasmine has white/yellow fragrant flowers.

Periwinkle (Vinca rosea/Catharanthus roseus) is called 'Sadaphuli' in Marathi, meaning 'always flowering' for its year-round blooms. It's a common medicinal and ornamental plant in Maharashtra. Tulsi is holy basil, Mogra is Arabian jasmine, and Chapha is a different flower (Parijaat/Harshringar).

Terrestrial planets are those composed primarily of rock and metal, with solid surfaces. In our solar system, Mercury, Venus, Earth, and Mars are the four terrestrial planets located in the inner solar system. They are characterized by their relatively small size, high density, and lack of ring systems, unlike the gas giants in the outer solar system.

All four gas giants in our solar system have ring systems. Saturn's rings are the most prominent and visible, but Jupiter, Uranus, and Neptune all possess ring systems as well, though they are much fainter and less massive than Saturn's.

Scientists estimate our solar system formed approximately 4.6 billion years ago from a collapsing cloud of gas and dust. This age is determined by radiometric dating of the oldest meteorites and lunar samples.

Proxima Centauri is the closest star to our Sun, located approximately 4.24 light-years away. It is part of the Alpha Centauri star system but is closer than the Alpha Centauri A and B binary pair.

Atoms are mostly empty space because the nucleus is tiny compared to the overall size of the atom, with electrons occupying the vast empty space around it. Since granite is made of atoms, and atoms are mostly empty space, granite is too.

Oxygen has atomic mass approximately 16 amu while hydrogen has atomic mass approximately 1 amu. Therefore, an oxygen atom is 16 times heavier than a hydrogen atom.

Oxygen has atomic number 8 (8 protons). Removing 2 protons leaves 6 protons, which is carbon (atomic number 6). This changes the element itself.

Adding a neutron to helium (2 protons) creates helium-3, which is still helium - just a different isotope. The element doesn't change because the number of protons remains the same.

Chemical properties are determined by how atoms interact and bond, which depends on the valence electrons - the electrons in the outermost shell. These are the electrons involved in chemical reactions.

If an atom decays to an intermediate state instead of the ground state, the energy difference is smaller, so the emitted photon has lower frequency and longer wavelength. Red light has lower energy than green light.
