General Science and Technology Quiz

Pluto was reclassified from a planet to a dwarf planet by the IAU in 2006. The term 'planetoid' is sometimes used as a synonym for dwarf planet or small solar system body. However, 'dwarf planet' is now the preferred scientific term over 'planetoid'.

Saturn is the second largest planet in our solar system after Jupiter. Saturn has a diameter of about 116,460 km, compared to Jupiter's 139,820 km. Uranus is the third largest, followed by Neptune.

Neptune is named after the Roman god of the sea (Poseidon in Greek mythology). The other planets also bear names from Roman mythology: Jupiter (king of gods), Uranus (sky god), but Pluto (named for underworld god, not sea god).

Titan is the largest moon of Saturn and the only moon known to have a dense atmosphere. It's larger than the planet Mercury. Mars has two small moons (Phobos and Deimos), Jupiter has many moons including Ganymede, and Neptune has Triton among others.

Jupiter has the shortest day of all planets, rotating once every ~9.9 hours. Its rapid spin creates powerful storms and gives it an oblate shape. Mercury rotates slowly (59 Earth days), Venus extremely slowly (243 days retrograde), and Earth in 24 hours.

Uranus holds the record for the coldest temperature measured in the solar system (-224°C). Neptune is further away but has more internal heat. Pluto is no longer classified as a major planet, and Mercury is the closest planet to the sun, making it very hot.

Uranus is the coldest planet in the solar system, with a minimum atmospheric temperature of -224°C. While Neptune is further from the sun, Uranus has a unique internal heat structure that makes it colder. Pluto is classified as a dwarf planet, and Mercury is extremely hot on its sun-facing side.

Venus is the brightest planet in our solar system as seen from Earth. This is due to its proximity to Earth and its thick atmosphere of sulfuric acid clouds, which reflect about 70% of the sunlight that hits it.

When you toss a coin in a running train, it falls in the same place due to inertia. The coin shares the train's horizontal velocity when tossed, so it continues moving forward at the same speed as the train while in the air.

An adiabatic process is one in which no heat is exchanged between a system and its surroundings (Q=0). An isothermal process occurs at constant temperature, and an isobaric process occurs at constant pressure. The question phrasing 'process of constant heat' refers to the lack of heat transfer.

According to the fundamental law of electrostatics, like charges (positive-positive or negative-negative) repel each other, while opposite charges attract. This is a basic principle of physics.

It is impossible to separate the north and south poles of a magnet. If you cut a magnet in half, you simply get two smaller magnets, each with its own north and south pole. Magnetic monopoles have never been observed in nature.

In Albert Einstein's famous mass-energy equivalence formula, E=mc², 'E' stands for energy, 'm' stands for mass, and 'c' stands for the speed of light in a vacuum. 'Momentum' and 'mole' are different physical concepts with their own distinct symbols.

Mysore (now Mysuru) was the first city in India to provide free Wi-Fi to its citizens in 2004. While cities like Bangalore and Hyderabad are major tech hubs, Mysore pioneered the implementation of a city-wide Wi-Fi network in the Indian context.

Konrad Zuse, a German engineer, created the Z3 in 1941, which was the world's first working programmable, fully automatic digital computer. He also developed Plankalkül, the first high-level programming language, for his machines. Babbage designed mechanical computers but lacked a modern 'language'.

Robert Edwards and Patrick Steptoe (note: Patrick, not Patric) developed the in vitro fertilization (IVF) technique that led to the birth of Louise Brown, the first test tube baby, in 1978. Their combined work makes 'Both' the correct answer.

Max Knoll and Ernst Ruska co-invented the electron microscope in 1931. Ruska was later awarded the Nobel Prize in Physics for this achievement. Leeuwenhoek is known for early light microscopes, and Millikan is famous for the oil-drop experiment measuring electron charge.

Aryabhata, the 5th-century Indian mathematician and astronomer, stated that the Earth is spherical and rotates on its own axis. He also correctly explained that the apparent motion of stars is due to this rotation. Pythagoras also believed in a spherical Earth, but Aryabhata's work specifically detailed the axial rotation.

To answer this question, we need to have some knowledge about the history of oil drilling.

The correct answer is B. Edwin Drake.

Explanation:

A. John Dalton: John Dalton was an English chemist and physicist who is best known for his work on modern atomic theory. He did not have any involvement in drilling for oil.

B. Edwin Drake: Edwin Drake is widely recognized as the first person to successfully drill for oil beneath the Earth's surface. In 1859, he drilled the first commercial oil well in Titusville, Pennsylvania, USA. This event marked the beginning of the modern oil industry.

C. Alfred Wegener: Alfred Wegener was a German meteorologist and geophysicist who is best known for his theory of continental drift. His contributions were related to plate tectonics and the movement of Earth's continents, not oil drilling.

D. Justus Von Liebig: Justus Von Liebig was a German chemist who made significant contributions to the field of organic chemistry. He is known for his work on nitrogen-based fertilizers, not oil drilling.

Therefore, the correct answer is B. Edwin Drake.

NaCl (sodium chloride) is commonly known as common salt or table salt. It's the most familiar salt used in food preservation and seasoning. Phenol is C6H5OH, and 'oil' and 'sugar' are not specific compounds.
