NCERT Grade 11 Physics Chapter 2, Units and Measurement, will strengthen your basic concepts about what is a unit, base units, derived units, system of units and others. It will help you to understand the what is the need of an international system of units and how are they decided. In this chapter, complexities of units and measurement shall be dealt with in a comprehensive manner. Units are used to measure different dimensions such as length, breadth, mass, etc. One shall also learn on alternative methods to measure length and estimation of very small distances like size of a molecule. Similarly, measurement of time, accuracy, precision of instruments will also be learnt in this chapter. Different instruments are used to measure different dimensions. One can easily learn the operations of a pendulum clock, Vernier calliper, scale and other instruments required to measure the physical quantities on micro and macro level through this chapter, Units and Measurement. It will help the learner to understand the identification of errors during measurement, absolute error, zero error, relative error and other concepts when dealing with measurement and units. This chapter is a part of Unit I. The topics and sub-topics in Chapter 2 Units and Measurement are given below. We cover all exercises in the chapter given below:- Chapter 2 - 33 Questions with Solution.

For class 12th, there are test in three categories Level 1 Easy questions test , Level 2 Average and board questions and Level 3 Difficult questions.

Tiwari Academy is a student centric educational web portal which provides quality test papers and study materials for the students preparing for CBSE or targeting various entrance exams. During past few years, a number of surveys on students were made to better understand their problems regarding their studies and their basic requirement.

This site is basically the concluded solution of the surveys. This is done as per your feedback and suggestions. Will the same source be in resonance with the pipe if both ends are open? The tension in the string A is slightly reduced and the beat frequency is found to reduce to 3 Hz. If the original frequency of A is Hz, what is the frequency of B? This is because frequency is directly proportional to the square root of tension.

Ans : a A node is a point where the amplitude of vibration is the minimum and pressure is the maximum. On the other hand, an antinode is a point where the amplitude of vibration is the maximum and pressure is the minimum Therefore, a displacement node is nothing but a pressure antinode, and vice versa.

These waves get reflected back toward them by obstacles. A bat receives a reflected nave frequency and estimates the distance, direction, nature, and size Of an obstacle with the help Of its brain senses. Hence, one can distinguish between the notes produced by a sitar and a violin even if they have the same frequency Of vibration.

They can sustain shearing stress. Since fluids do not have any definite shape, they yield to shearing stress. The propagation of a transverse wave is such that it produces shearing stress in a medium.

The propagation Of such a wave is possible only in solids, and not in gases. Both solids and fluids have their respective bulk moduli.

They can sustain compressive stress. Hence, longitudinal waves can propagate through solids and fluids. These waves travel in a dispersive medium with different velocities, depending on the nature of the medium.

This results in the distortion of the shape of a wave pulse. These relative motions produce no effect on the speed of sound.

Therefore, the speed of sound in air in both the cases remains the same, i. What are the frequency, wavelength, and speed of sound for an observer standing on the station's platform?

Is this velocity equal to the velocity of wave propagation? However, the speed of the sound pulse remains the same, which is equal to the speed of sound in that medium. The other end passes over a pulley and is tied to a pan containing a mass of 90 kg. The pulley end absorbs all the incoming energy so that reflected waves at this end have negligible amplitude.

The amplitude of the wave is 5. Unlike a gas, the earth can experience both transverse S and longitudinal P sound waves. Typically the speed of S wave is about 4.

A seismograph records P and S waves from an earthquake. The first P wave arrives 4 min before the first S wave.
