1. Question
1 pointsCategory: Science and TechnologyConsider the following statements regarding Advanced Air Defence (AAD) Interceptor
Missile known as Ashwin
- It is an anti-ballistic missile designed to intercept incoming ballistic missiles in the endoatmosphere
at an altitude of 30 km
- It is a single-stage, solid-fuelled missile
- It is part of double-tiered missile defense system that India‘s military hopes will provide a multi-layered defense system against any potential ballistic missile strike.
Which of the given above statements is/are correct?
Correct
The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect from ballistic missile attacks. It is a double-tiered system consisting of two interceptor missiles, namely the Prithvi Air Defence (PAD)/ Pradyumna missile for high altitude interception, and the Advanced Air Defence (AAD)/ Ashwin Missile for lower altitude interception. This two-tiered shield should be able to intercept any incoming missile launched 5,000 kilometres away.

2. Question
1 pointsCategory: Science and TechnologyBased upon applications we have different satellite orbits. The ones that receive the most attention are the geostationary orbit used as they are stationary above a particular point on the earth. In this context consider the following statements with respect to Geostationary Orbit:
- Geostationary orbit is a circular orbit which encircles the earth parallel to the equator.
- A satellite placed in this orbit tends to remain in a stationary condition.
- Every geostationary orbit is a geosynchronous orbit but not the vice versa.
Which of the given above statements is/are correct?
Correct
A geostationary orbit is a geosynchronous orbit which is circular in nature and it lies exactly above the line of the equator. With those additional constraints, it remains stationary above a fixed point on the equator for an observer from the ground because it synchronises the time period and movement of the earth.

3. Question
1 pointsCategory: Science and TechnologyRecent scientific award titled as ―MANAK‖ is given under which of the following scientific scheme?
Correct
The Department of Science and Technology (DST) is revamping a popular outreach programme, conceived to hook children early on to science and research, and tweaking it to reflect a thrust on technology and exposing children to the ―innovation cycle.‖ The INSPIRE Awards (Innovation in Science Pursuit for Inspired Research), as they are now called, will be rechristened MANAK (Million Minds Augmenting National Aspirations and Knowledge) from this year. According to officials, it‘s a ―reformulation‖ of the existing programme and reflects a thrust on original ideas, which aim to use technology to solve problems, rather than merely display a clever idea for an exhibition.

4. Question
1 pointsCategory: Science and TechnologyThe function of Deuterium Oxide in a nuclear reactor is to
Correct
Heavy water (D 2O), also called deuterium oxide, water composed of deuterium, the hydrogen isotope with a mass double that of ordinary hydrogen, and oxygen. The heavy water produced is used as a moderator of neutrons in nuclear power plants. A moderator is a material used in a nuclear reactor to slow down the speed of neutrons produced from fission. By slowing the neutrons down the probability of a neutron interacting with Uranium-235 nuclei is greatly increased thereby maintaining the chain reaction.

5. Question
1 pointsCategory: Science and TechnologyA team of scientists at NASA with the European Space Agency are working to probe dark energy or the existence of dark matter. Consider the following statements in this regard.
- Dark matter is called so because it does not interact with light.
- Dark matter interacts with ordinary matter through gravity and binds galaxies together like an invisible glue.
- While dark matter pulls matter together, dark energy pushes the universe apart at ever increasing speed.
- Dark matters are potentially effective in many dignostic devices such as PET scanners.
Which of the statements given above are correct?
Correct
Dark matter is a type of matter hypothesized in astronomy and cosmilogy to account for a large part of the mass that appears missing from the universe, it does not interact with light. It is also hypothesized that it interacts with ordinary matter through gravity and binds galaxies, and it pushes the universe apart.
