In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. B: The sound source creates vibrations in the surrounding medium.  C: The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. D: Sound can propagate through a medium such as air, water, and solids as longitudinal waves and also as a transverse wave in solids.
In longitudinal waves, particles vibrate in the . . . . . . . . direction of transmission the propagation of the wave.
Which of the following statements is/are correct regarding vegetative propagation of plants? 1. Vegetative propagation produces a clonal population. 2. Vegetative propagation helps in eliminating the virus 3. Vegetative propagation can be practised most of the year. Select the correct answer using the code given below.
The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below.  Which among the following below options does not talk about the effects of these particles on the environment?
Consider the following statements: a. Beta particles are negatively charged and are more penetrating than Alpha particles, which are positively charged. b. Gamma particles are neutral and are more penetrating than Beta-particles. c. In general neutral particles can be said to be having very high penetrating power.
