FAQs on NCERT Books Free Download for Class 11 Physics Chapter 2 - Units and Measurement
1. What is the significance of using NCERT Books for Class 11 Physics Chapter 2 – Units and Measurement?
CBSE guidelines apply to NCERT books for conceptual learning. These books can be used both as reference guides and as study aids for school exams, board exams, and other competitive tests. Board exams typically utilize NCERT books as reference materials. During examination times, NCERT is the only book that can be relied upon. There are significant advantages in NCERT books over other books, such as the fact that they are significantly cheaper. As a result, compulsory education is available to students from all socioeconomic levels. Vedantu's website or mobile app contains free study materials that can assist you in learning more.
2. How will you measure the length of a line according to the concepts of Chapter 2 of Class 11 Physics?
It is a tricky question and was not easy to answer; it was easy to think of a way to solve it. The best and straightforward way is to measure the length of a line. You need a gauge.
If you want to measure it short, make it long enough.
If you want to measure it long, make it short enough.
If you want to measure the distance between the mountain and the lake, make the mountain your footstool.
The distance between heaven and earth is one step.
3. Do I need to practise all the questions provided in Chapter 2 – Units and Measurement of Class 11 Physics?
It would be very useful if you practiced all the questions provided in Physics Chapter 2 as these questions will be tested in any upcoming exams. Also, reading the Chapter questions is also good for your Units and Measurement knowledge as you will be able to grasp the concepts clearly by practicing all the questions. Most of these questions can be answered without practicing, since the purpose of these questions is to get familiar with the terminology, the meaning of each subject, the type of answers and how to solve them.
4. How is the mass measured according to the concepts taught in Chapter 2 of Class 11 Physics?
When we take a mass measurement we measure the mass of a single mass object. It is usually done by measuring the mass of the object we are dealing with and using that mass to calculate the mass of the room we are in. The most obvious way of measuring the mass of a single mass object is to put the object into the gravitational field of a standard object, say the Earth. That mass object will weigh the same in any gravitational field and the same gravitational field will weigh the same object. We call that the Law of Universal Gravitation.
5. According to the concepts taught in Chapter 2 of Class 11 Physics, what is SONAR (sound navigation and ranging)?
Today, with the introduction of precise recording electronics and innovations in Sonar design, the sensitivity of Sonar for finding and mapping the bottom has greatly increased.
SONAR (sound navigation and ranging) technology was first developed in the late 1940’s. It is capable of mapping the ocean’s bottom with enormous accuracy, which is why it is called ‘bottom searching’ technology. SONAR technology uses a sonar pulse, which is bounced off the seafloor and recorded using a detector. With this data, the sound pulses can be processed to reveal the features of the underwater terrain and the objects and sources of fish.
