Daily Quiz – 11th Apr 2024 By adminApril 17, 2024Quiz Daily Quiz - 11th Apr 2024 Daily Quiz - 11th Apr 2024 1 / 5 In the context of digital technologies for entertainment, consider the following statements: In Augmented Reality (AR), a simulated environment is created, and the physical world is completely shut out. In Virtual Reality (VR), images generated from a computer are projected onto real-life objects or surroundings. AR allows individuals to be present in the world and improves the experience using the camera of smart-phone or PC. VR closes the world, and transposes an individual, providing complete immersion experience.Which of the statements given above is/are correct? 1 and 2 only 3 and 4 only 1, 2 and 3 only 4 only Exp) Option b is the correct answer.Statement 1 is incorrect: Augmented Reality (AR) does not create a simulated environment, but rather adds virtual elements to the real world. For example, an AR app can show you how a piece of furniture would look in your room, or how a tattoo would look on your skin. The physical world is not shut out, but rather enhanced by AR.Statement 2 is incorrect: Virtual Reality (VR) does not project images onto real-life objects, but rather blocks out the real world and immerses the user in a digital environment. For example, a VR headset can make you feel like you are in a different place, such as a game world, a movie scene, or a historical site. The real-life objects or surroundings are not visible, but rather replaced by VR.Statement 3 is correct: AR allows users to interact with the real world and enhance their experience with virtual information or objects, using devices such as smartphones or PCs. For example, an AR app can show you directions on the street, or information about a landmark, using the camera of your smartphone or PC.Statement 4 is correct: VR transports users to a different reality and provides a complete immersion experience, using devices such as headsets or goggles. For example, a VR headset can make you feel like you are flying in the sky, or diving in the ocean, providing a sense of presence and realism.

Polar orbiting satellite senses only the polar regions of Earth. All Geostationary orbits are Geosynchronous, while the vice versa is not true. Satellites in the Lower Earth Orbit have a lower orbital velocity than the ones in higher orbits.How many of the statements given above are correct? Only one Only two Only three All four Statement 1 is incorrect. Low Earth Orbit (LEO) satellites do not have to always orbit along Earth‟s equator. Satellites in Geostationary orbit have to always orbit along Earth‟s equator. Low Earth Orbiting satellites do not always have to follow a particular path around Earth in the same way – their plane can be tilted. This means there are more available routes for satellites in LEO, which is one of the reasons why LEO is a very commonly used orbit. It is the orbit most commonly used for satellite imaging, as being near the surface allows it to take images of higher resolution.Statement 2 is incorrect. Polar orbiting satellites are in an orbital plane that is inclined at nearly 90 degrees to the equatorial plane. This inclination allows the satellite to sense the entire globe, including the Polar Regions, providing observations of locations that are difficult to reach via the ground. Many polar-orbiting satellites are considered sun synchronous, meaning that the satellite passes over the same location at the same solar time each cycle. Almost all satellites used for remoted sensing and Geographic Information System (GIS) work are polar orbiters. Statement 3 is correct.The Geosynchronous Orbit and Geostationary Orbit are defined on the basis of following conditions:Condition 1: If the satellite is placed at an altitude of 35786 km above the Earth, where its velocity is such that it takes exactly 23 hrs 56 minutes 4 sec to revolve around the Earth.Condition 2: If the Orbital plane and the Equatorial plane lies in the same plane throughout. If both the above conditions are satisfied, the satellite is said to be placed in Geostationary orbit. If onlycondition 1 is satisfied, the orbit is called a Geosynchronous orbit.Thus, all Geostationary orbits are Geosynchronous as well, while the vice versa is not true. The Geostationary satellites remain permanently fixed with respect to a point on earth while the Geosynchronous satellites have a varying position with respect to a point on earth and wider coverage. Geosynchronous Transfer Orbit refers to an elliptical Geosynchronous orbit from where the satellite is transferred to a higher orbit or to Geostationary orbit through orbit maneuvering.Statement 4 is incorrect. The satellites in the LEO travel much faster (i.e., they have a higher orbital velocity) than the ones in higher orbits because the gravitational pull of Earth is highest in the LEO, satellites in the LEO are more strongly pulled by the planet than those in the MEO or geostationary orbit. Statement 1 is incorrect. Low Earth Orbit (LEO) satellites do not have to always orbit along Earth‟s equator. Satellites in Geostationary orbit have to always orbit along Earth‟s equator.

In Vitro Fertilisation. Artificial Insemination (AI) Gamete Intra Fallopian Transfer (GIFT) Zygote Intra Fallopian Transfer (ZIFT)How many of the above are types of Assisted Reproductive Technology (ART)? Only two Only three Only four All five Exp) Option c is the correct answer.Assisted Reproductive Technology (ART) refers to a variety of procedures used to treat infertility. The technology aids in obtaining a pregnancy through multiple methodologies such as In Vitro Fertilisation Artificial Insemination etc.Option 1 is incorrect: Intra Uterine Devices (IUDs) is one of the most widely accepted methods of contraception and is not a type of assisted reproductive technology. IUDs increase phagocytosis of sperms within the uterus and release copper ions which suppress sperm motility and the fertilising capacity of sperms. The hormones released by IUDs make the uterus unsuitable for implantation and the cervix hostile to the sperms. Hence IUDs are ideal contraceptives for the females.Option 2 is correct: In vitro fertilisation is a type of fertility treatment where fertilisation occurs in a laboratory, instead of within the body. It involves extracting one or more eggs from an ovary and placing them in a petri dish with donated sperm. In vitro fertilisation is a type of ART.Option 3 is correct: Artificial insemination is one of the types of Assisted Reproductive Technology (ART). Artificial insemination involves inserting sperm directly into a woman's uterus to increase the chance of fertilisation. It is used to correct Infertility cases either due to inability of the male partner to inseminate the female or due to very low sperm counts.Option 4 is correct: Gamete intra fallopian transfer (GIFT) is one of the types of Assisted Reproductive Technology (ART). GIFT involves three persons i.e, transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce one but can provide a suitable environment for fertilisation and further development.GIFT is a three-step procedure that involves removing the eggs, combining them with sperm, and immediately placing them in the fallopian tubes, where the egg is fertilised.Option 5 is correct: Zygote intrafallopian transfer (ZIFT) is an Assisted Reproductive Technology which involves procedure similar to „In vitro fertilisation‟, the difference being that the fertilised embryo is transferred into the fallopian tube instead of the uterus.

Sodium lamps produce light in 360 degrees, but it is not so in the case of LED lamps. As street-lights, sodium lamps have longer life span than LED lamps. The spectrum of visible light from sodium lamps is almost monochromatic while LED lamps offer significant colour advantages in street-lighting.Select the correct answer using the code given below: 3 only 2 only 1 and 3 only 1, 2 and 3 Exp) Option c is the correct answer.Statement 1 is correct. Sodium lamps produce light in 360 degrees but it is not so in the case of LED lamps. LED lamps have 180-degree bulb angle to preserve light efficiency and allow for target lighting over areas.Statement 2 is incorrect. As street lights, sodium lamps have on an average shorter lifespan than LED lamps. High Pressure Sodium lamps tend to have a lifespan averaging 24,000 hours. Whereas, LED lamps lifespan ranges from 25,000 to 200,000 hours.Statement 3 is correct. The spectrum of visible light from sodium lamps is almost monochromatic as they are known for their warm yellow glow. On the other hand, LED lamps offer significant colour advantages in street-lighting. LEDs offer variety of colour options providing better lighting solutions than High Pressure Sodium counterpart.
