A light-year is a unit of length used to express astronomical distances. It is about 9 trillion kilometres or 6 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word "year", the term light-year is sometimes misinterpreted as a unit of time.
Luminous intensity is measured in Candela.
Bar is a unit of Pressure.

Question :Consider the following statements:
Richter scale measures the magnitude of energy released from an earthquake on a logarithmic scale.
The Mercalli scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures.
Select the correct answer using the codes given below.
The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the size of an earthquake. The Richter scale, developed in the 1930s, is a base-10logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude, as recorded on a standardized seismograph at a standard distance.

White-collar worker is a person who performs professional, managerial, or administrative work. White-collar work is performed in an office, cubicle, or other administrative setting.
Blue-collar worker is a working class person who performs non-agricultural manual labour. Blue-collar work may involve skilled or unskilled manufacturing, mining, sanitation, custodial work, oil field work, construction, mechanical maintenance, warehousing, firefighting, technical installation and many other types of physical work.
Pink-collar worker performs jobs in the service industry. Example: Librarian, maid, flight attendant, receptionist, secretary, etc.
White Collar Worker is a salaried professional, typically referring to general office workers and management. It originates from colour of dress shirts worn by professional and clerical workers.
Green Collar Worker is a worker who is employed in the environmental sectors of the economy. Example: People working in alternate energy sources like solar panels, Greenpeace, World Wide Fund for nature etc.
Red-collar People engaged in primary activities due to the outdoor nature of their work.
Gold Collar Worker is a newly formed phrase which has been used to describe either young, low-wage workers who invest in conspicuous luxury (often with parental support). It is also used to refer to highly-skilled knowledge people who are highly valuable to the company. Example: Lawyers, doctors, research scientists, etc. It also includes govt. employees.
Black Collar Worker is used to refer to workers in the mining or the oil industry. Sometimes, it is also used to refer to people who are employed in black marketing activities.
Open Collar Worker is a worker who works from home, especially via the internet.

Question :Consider the following aboutLi-Fi.
Direct line of sight is not necessary for Li-Fi to transmit a signal.
It is based on radio frequency.
Select the correct answer using the codes given below.
Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. It is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.
It is wire and uv visible-light communication or infrared and near-ultraviolet instead of radio-frequency spectrum, part of optical wireless communications technology, which carries much more information and has been proposed as a solution to the RF-bandwidth limitations.
Direct line of sight is not necessary for Li-Fi to transmit a signal; light reflected off the walls can achieve 70 Mbit/s.
The light waves cannot penetrate walls which makes a much shorter range, though more secure from hacking, relative to Wi-Fi.

It is a system where magnetically levitating capsules are sent at high speeds through low-pressure tubes, thereby potentially reducing transport time — of people and goods — by more than 80%.
While the term Hyperloop is in some countries a registered trademark of Space Exploration Technologies Corporation (SpaceX) for the high speed transportation of passengers and goods in partially evacuated tubes, the Hyperloop concept has been explicitly open-sourced by Musk and SpaceX, and others have been encouraged to take the ideas and further develop them.

Question :Consider the following pairs of International boundaries and the Countries involved:
Durand Line : India-Pakistan
Radcliffe Line : Pakistan-Afghanistan
McMahon Line : India-China in eastern and western sector
The Durand Line is the 2,430-kilometre (1,510 mi) international border between Pakistan and Afghanistan. It was established in 1896.
The Radcliffe Line was published on 17 August 1947 as a boundary demarcation line between India and Pakistan upon the Partition of India. It was named after its architect, Sir Cyril Radcliffe, who, as chairman of the Border Commissions, was charged with equitably dividing 175,000 square miles (450,000 km2) of territory with 88 million people. Today its western side still serves as the Indo-Pakistani border and the eastern side serves as the India-Bangladesh border.
The McMahon Line is a line proposed by McMahon in the Shimla Accord which was considered valid by Tibetans and invalid by Chinese government. It is the effective boundary between China and India, although its legal status is disputed by the Chinese government.
The line is named after Sir Henry McMahon, foreign secretary of the British-run Government of India and the chief negotiator of the convention at Shimla. It extends for 550 miles (890 km) from Bhutan in the west to 160 miles (260 km) east of the great bend of the Brahmaputra River in the east.
Medicine Line is the border between Canada and the United States. 49th Parallel is the boundary between USA and Canada.
Graphene is a crystalline allotrope of carbon with 2-dimensional properties.
It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
A fullerene is a molecule of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes.
The material was isolated and characterized in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester. Research was informed by existing theoretical descriptions of its composition, structure, and properties. This work resulted in the two winning the Nobel Prize in Physics in 2010 "for ground breaking experiments regarding the two-dimensional material graphene."
