K.C. Sinha Class 10th Mathematics Book | Student's Friends Class 10th Book 1.1. भूमिका (प्रस्तावना) (Introduction) :    कक्षा IX में हमने वास्तविक संख्याओं के बारे में पढ़ा है कि ये परिमेय (Rational) और अपरिमेय (Irrational), दो प्रकार की होती हैं। यहाँ हम धनात्मक पूर्णाकों (प्राकृतिक संख्याओं) के दो अति महत्त्वपूर्ण गुणों का अध्ययन करेंगे। ये गुण हैं-    यूक्लिड-विभाजन-एल्गोरिथ्म (Euclid's division algorithm) और अंकगणित की आधारभूत प्रमेय (Fundamental Theorem of Arithmetic) | यूक्लिड विभाजन एल्गोरिथ्म के अनुसार प्रत्येक धनात्मक पूर्णाक (प्राकृतिक संख्या) a को किसी अन्य (another) धनात्मक पूर्णाक b से इस प्रकार विभाजित किया जा सकता है कि शेषफल (Remainder) r प्राप्त हो, जहाँ 0≤r<b । इस कथन से स्पष्ट है कि यूक्लिड विभाजन ऐल्गोरिथ्म का सम्बन्ध पूर्णाकों की विभाज्यता से है। वास्तव में पूर्णाकों की विभाज्यता से सम्बन्धित यूक्लिड विभाज्यता एल्गोरिथ्म के अनेक महत्त्वपूर्ण अनुप्रयोग (Application) हैं। उदाहरण (जैसे) : (i) 25 को जब 8 से विभाजित किया जाता है तो भागफल 3 तथा शे

B.Sc. Part-1 Physics Practical Book Honours and Subsidiary Paper. B.Sc. part-1 physics Viva-Voce questions and answers. Honours first year physics practical experiments and viva-voce. Aim of the Experiment : Determination of surface tension of liquid (water) by the method of Ripples. Apparatus Required:     (i) A pair of electrically maintained tuning forks of same frequency (or one electrically maintained tuning fork, a non-discharge-tube and a Rumkorft's induction coil).    (ii) A battery of cells.    (iii) A plug key.    (iv) A large and shallow rectangular porcelain trough (ripple tank), ex- perimental liquid (aniline or water).    (v) A porcelain scale with MM graduations.    (vi) A thermometer and    (vii) A stroboscopic diso arrangement. Theory:         The method is based upon generating ripples on water surface and measuring the wavelength 'λ' of these ripples. The velocity v of propagation of such ripples is given by. Where,          g = accel

B.Sc. Part-1 Practical Chemistry Book Honours and Subsidiary Paper. Analysis is done to find out the constituents and their amount in a compound. In the analysis of a solid sample, the ingredients present in it can be salts, acids, bases, metals and their compounds; in case of a solution, it dissociates into two charged species called Cation and Anion. The positively charged species are called cations or basic radicals while the negatively charged species are called Anions or Acidic radicals.  Analysis of a sample may be of two categories:  (A) Qualitative Analysits  (B) Quantitative Analysis Qualitative Analysis:        Qualitative Inorganic analysis or Salt Analysis is done to determine the constituents present in a given sample the processes and methods involved in Qualitative Analysis, make us enable to state the name of the constituents present in it. The basis of the determination of the constituents is the observed chemical behaviours of them. Types of Qualitative An
