To address the question regarding the swelling of dry plant materials or seeds when kept in water, we need to identify two essential conditions for this phenomenon, known as imbibition, to occur. Here’s a step-by-step breakdown of the solution: ### Step-by-Step Solution: 1. **Understanding Imbibition**: - Imbibition is the process through which dry plant materials or seeds absorb water, leading to swelling. This is a specific type of diffusion where water is taken up by solids. 2. **Condition 1: Water Potential Gradient**: ...

Ravi is a student of mechanical engineering studying in one of the engineering colleges. The other day he saw an old man who suddenly collapsed as he walked out of the house in his neighbourhood. Ravi the emergency ward of the hospital. On getting the medical aid, the old man soon goy recovered. He did not forget to thank Ravi for the timely help he rendered. He was wondering that in his times to get the telephone connection. One had to wait for years whereas these days it takes no time to get the connection. Ravi told him it was all because of the technological progress/deveolpement due to which the simple phenomenon in physics could be easily used. Answer the following questions based on the above : (a) To which phenomenon in physics was Ravi referring to, which made the land line links so easily accessible? (b) What are the essential conditions required to observe this phenomenon ? (c) Write two values displayed by Ravi and the old man in this episode.

When any two sides and one of the opposite acute angle are given, under certain additional conditions two triangles are possible. The case when two triangles are possible is called the ambiguous case. In fact when any two sides and the angle opposite to one of them are given either no triangle is posible or only one triangle is possible or two triangles are possible. In the ambiguous case, let a,b and angle A are given and c_(1), c_(2) are two values of the third side c. On the basis of above information, answer the following questions The value of c_(1)^(2) -2c_(1) c_(2) cos 2A +c_(2)^(2) is
