Miscellaneous (Physics) (Part-2)

ISRO built India's first satellite, known as Aryabhata.

1. It was launched on April 19, 1975, with the assistance of the Soviet Union.
2. The satellite was named after the renowned 5th-century Indian astronomer and mathematician.
3. Aryabhata was designed to conduct experiments in X-ray astronomy, aeronomics, and solar physics.
4. While its operational life was short due to a power failure, it was a crucial first step and a significant milestone in India's space program, demonstrating the country's ability to design and build a satellite.

1. Mangalyaan was India's first interplanetary mission.
2. The indigenously- built space probe has been in the Martian orbit since September 24, 2014.
3. The mission made India the first Asian country, and the fourth in the world after Roscosmos, NASA, and the European Space Agency, to get to the planet.
4. China referred to India's successful Mangalyaan as the "Pride of Asia".

1. Saras is a multipurpose civil aircraft.
2. Bhishma is a tank designed by Russian technology.
3. BrahMos (BRAHMOS) is a supersonic cruise missile developed in a joint venture between India's DRDO and Russia's NPO Mashinostroeyenia.
4. Brahmos is named after the Brahmaputra of India and the Muskva river of Russia.
5. INSAT-3C is a satellite.

HAL Tejas is an indigenous Light Combat Aircraft of India.

• The Tejas (meaning "radiance" in Sanskrit) is a single-engine, multirole light combat aircraft designed by the Aeronautical Development Agency (ADA) and manufactured by Hindustan Aeronautics Limited (HAL).
•  It is the smallest and lightest multi-role supersonic fighter aircraft in its class.
• The Tejas was developed to replace India's aging MiG-21 fighter jets and to enhance the country's indigenous aerospace capabilities.

This means it measures the ratio of the liquid's density to the density of a reference liquid, typically water.

It represents the direction a compass needle would point in.

It's essentially a calibrated glass tube with a weighted bulb that floats in the liquid, allowing you to determine the liquid's density based on how deeply it sinks.

Hence it is used in Solar Panels.
Silicon is also preferred for IC manufacturing because pure silicon is the least affected by water, acid or steam.

It can withhold a high temperature. For the abundant property of Silicon suitable to industrial production, it is also used in Optical glass.
Ink pen is made of carbon black.

It explains key superconducting phenomena like zero electrical resistance and the Meissner effect, where a superconductor expels magnetic fields from its interior.

The theory is based on the concept that a macroscopic quantum state of electrons, or "super-electrons," carries the current with zero resistance.

• They contain several million of stars and their size can range from few thousands to several hundred thousand light years.
• They have different shapes and brightness and can be found alone, in pairs or in clusters.
• The galaxy of Earth is called Milky Way.
