UPSC Quiz: Science & Tech - Hydrogen, Uranium, AstroSat
This article is a science and technology quiz from UPSC Essentials.
The quiz includes questions about hydrogen fuel, its advantages, and challenges.
Another question focuses on fundamental forces of nature.
It also explores topics like hypoxia and hypothermia, their causes, and effects.
Additionally, questions address uranium, its properties, and isotopes, as well as AstroSat, India’s first multiwavelength space observatory.
The quiz helps people to test their knowledge of current science and technology topics.
Hydrogen fuel produces electricity and water vapor.
The biggest challenge with hydrogen fuel is its low density.
Electromagnetism, gravity, strong, and weak nuclear forces are fundamental forces.
Hypoxia is caused by lack of oxygen, and hypothermia by low body temperature.
Uranium is the most common fissile material, and AstroSat is India's first multi-wavelength space observatory.
