कक्षा ९ / १० - हिंदी (ब) अपठित गद्यांश

अपठित गद्यांश

निम्नलिखित गद्यांश को ध्यानपूर्वक पढ़कर नीचे दिए गए प्रश्नों के उत्तर दीजिए :

समस्याएँ वस्तुत: जीवन का पर्याय हैं। यदि समस्याएँ न हों, तो आदमी प्राय: अपने को निष्क्रिय समझने लगेगा। ये समस्याएँ वस्तुत: जीवन की प्रगति का मार्ग प्रशस्त करती हैं। समस्या को सुलझाते समय, उसका समाधान करते समय व्यक्ति का तत्व उभरकर आता है। धर्म, दर्शन, ज्ञान मनोविज्ञान इन्हीं प्रयत्नों की देन हैं। पुराणों में अनेक कथाएँ यह शिक्षा देती हैं कि मनुष्य जीवन की हर स्थिति में जीना सीखे व समस्या उत्पन्न होने पर उसके समाधान के उपाय सोचे। जो व्यक्ति जितना उत्तरदायित्वपूर्ण कार्य करेगा, उतना ही उसके समक्ष समस्याएँ आएँगी और उनके परिपेक्ष्य में ही उसकी महानता का निर्धारण किया जाएगा। दो महत्वपूर्ण तथ्य स्मरणीय हैं - प्रत्येक समस्या अपने साथ संघर्ष लेकर आती है। प्रत्येक संघर्ष के गर्भ में विजय निहित रहती है। समस्त ग्रंथों और महापुरुषों के अनुभवों का निष्कर्ष यह है कि संघर्ष से डरना अथवा उससे विमुख होना लौकिक व पारलौकिक सभी दृष्टियों से अहितकर है, मानव-धर्म के प्रतिकूल है और अपने विकास को अनावश्यक रूप से बाधित करना है।

(क) 'समस्याएँ वस्तुत: जीवन का पर्याय हैं' का तात्पर्य है :

Chemistry - Acids and Bases - Indicators

Questions and Answers

Q2: What is an indicator? Give examples of indicators.

Answer:  An indicator is a dye or substance that changes colour or its smell when it is put into acid or a base. An indicator gives different colours in acid and base. Thus an indicator tells us if the given substance is an acid or base by changing its colour. The three common indicators are: Litmus, Methyl orange, phenolphthalein.

Class 7 - Maths - Properties of Integers (#cbsenotes)(#eduvictors)(#class7maths)

Class 7 - Mathematics - Properties of Integers 

1. Closure Property Under Addition

Integers are closed under addition, i.e. for any two integers,a and b, a+b is an integer. 
eg: 3 + 4 = 7
   -9 + 7 = 2


2. Closure Property under Subtraction: 

Integers are closed under subtraction, i.e. for any two integers,a and b, a-b is an integer.
eg:
-21 -(-9) = -12
8  -3    = 5

3. Closure Property under Multiplication: 

Integers are closed under multiplication, i.e. for any two integers,a and b, ab is an integer.
e.g.
5 × 6 = 30
-3 × -8 = 24
-3 × 7 = -21
