5. Question
1 pointsConsider the following statement with reference to Virtual Reality and Augmented reality
1.Augmented reality uses headset to place one in a computer generated world that you can explore

3. With virtual reality, one can explore an underwater environment. With augmented reality, one could see fish swimming through the world around you.
Which of the statements given above is/are incorrect?Correct
Option A is correct answer.
•Virtual reality (VR) and augmented reality (AR) are two technologies that are changing the way we use screens, creating new and exciting interactive experiences.
•Statement 1 and 2 are incorrect Virtual reality uses a headset to place you in a computer-generated world that you can explore. Augmented reality, on the other hand, is a bit different. Instead of transporting you to a virtual world, it takes digital images and layers them on the real world around you through the use of either a clear visor or smartphone.
•Statement 3 is correct.Incorrect

Question 6 of 10
6. Question
1 pointsWith reference to Quick Response (QR code) code, consider the following statement:
1. It is just a two-dimensional designs that can be scanned with smartphones
2. The QR code generally has four small squares placed in the the corners of a bigger square.
3. More number of squares denote larger volume of data stored or retrieved
4. QR codes are specific to the operating system of the smartphone device being used
Which of the statements given above is/are correct?Correct
Option A is correct answer.
•Statement 1 is correct. There are many variations of one-dimensional and two-dimensional barcodes, a lot of which look very similar. The QR code is just one of the two-dimensional designs that happens to be the most frequently used code to scan with smartphones.
•Statement 2 is incorrect. The QR code stands out with its three small squares placed in the lower and upper left corners and upper right corner. The overall code has a square shape composed of a matrix of small squares.
•Statement 3 is correct. More number of squares denotes more volume of data.
•Statement 4 is incorrect. Both iPhones and Android smartphones can scan QR codes directly from the main camera app, as long as it is using the latest iOS or Android software. You simply open the camera and point it towards the QR code, which will immediately recognise it and open a push notification requiring you tap it to finish the relevant operation.Incorrect

Question 7 of 10
7. Question
1 pointsWith reference to Neutron star consider the following statements:
1. Neutron stars are formed when a massive star runs out of fuel and collapses
2. They are found scattered throughout the galaxy in the same places where we find stars
3. Pulsars have very weak magnetic fields which funnel jets of particles out along the two magnetic poles
Which of the statements given above is/are correct?Correct
• Option A is correct answer.
• Statement 1 is correct. Neutron stars are formed when a massive star runs out of fuel and collapses. The very central region of the star – the core – collapses, crushing together every proton and electron into a neutron
• Statement 2 is correct. Since neutron stars began their existence as stars, they are found scattered throughout the galaxy in the same places where we find stars. And like stars, they can be found by themselves or in binary systems with a companion.
• Statement 3 is incorrect. Pulsars have very strong magnetic fields which funnel jets of particles out along the two magnetic poles.Incorrect
