National Bird Day: Why Birds Matter to Us

National Bird Day is celebrated every year on 5 January . This day is observed to spread awareness about birds, their importance in nature, and the need to protect them. Birds are beautiful living beings and play a very important role in keeping our environment healthy. Origin of National Bird Day National Bird Day was first celebrated in the year 2002 . It was started by bird lovers and environmental groups to protect birds from dangers like deforestation, pollution, and illegal hunting. The main aim of this day is to teach people, especially students, why birds are important and how we can help save them. Why Is National Bird Day Celebrated Every Year? National Bird Day is celebrated every year because many bird species are disappearing due to human activities. Cutting trees, using plastic, pollution, and climate change are harming birds and their homes. This day reminds us that: Birds need protection Nature should be respected Everyone has a responsibil...

Kinetic interpretation of temperature

Kinetic interpretation of temperature

  • Pressure of an ideal gas

  • M= mN
  • m = mass of one molecule
  • N = number of molecule in 1 gm-molecule (Avogadro number )



Conclusion

  • Mean kinetic energy of a molecule is directly proportional to the absolute temperature of the gas.
  • Mean square velocity of the molecule is directly proportional to the absolute temperature of the gas.
  • Amount of heat produced by a body is equal to the total kinetic energy of its molecules and its temperature is proportional to the mean kinetic energy of its molecules.
  • This is the kinetic interpretation of temperature.

Perfect gas equation

Electric field due to circular loop of charge | Electromagnetics

Electric field due to circular loop of charge Electric field The space around a charged particle in which another charge experience a force is known as electric field. The source of electric field is either a charge or a time varying magnetic field. If the value of electric field does not change with time, then it will be uniform electric field, otherwise it will be non-uniform electric field. Electric field due to circular loop of charge If λ is linear charge density, then the charge on d l dq = λ d l      ⇒     dq = (q / 2πa) d l Electric field at P due to charge dq Special cases When P lies at the centre of the loop i. e., r = 0, then E = 0 When P lies very far from the centre of the loop i. e., r >> a, then E = kq / r 2 In this case circular loop behaves as a point charge.

आवेश तथा उसके गुण | Charge and its properties in Hindi

आवेश तथा उसके गुण आवेश क्या है कोई नहीं जानता कि आवेश क्या है, केवल हम यह जानते हैं कि आवेश क्या कर सकता है तथा इसके गुण क्या हैं ? आवेश के प्रकार आवेश दो प्रकार के होते हैं, धनावेश तथा ऋणावेश। धनावेश प्रोटॉन के कारण होता है तथा ऋणावेश इलेक्ट्रॉन के कारण। तीसरे प्रकार का कोई आवेश ब्रहाण्ड में विद्यमान नहीं है। आवेश का क्वांटीकरण आवेश सदैव पैकेट के रूप में होता है, सतत्‌ नहीं। किसी वस्तु को दिया गया आवेश सदैव एक न्यूनतम आवेश का पूर्ण गुणज होता है यह न्यूनतम आवेश इलेक्ट्रॉन के आवेश के बराबर होता है, जिसका मान e = 1.6*10 -19 C होता है। q = ne,        यहां n = 0, 1, 2, ... आवेश संरक्षण का नियम आवेश को न तो उत्पन्न किया जा सकता है तथा न ही नष्ट किया जा सकता है, परन्तु इसे निकाय के एक भाग से दूसरे भाग में स्थानान्तरित किया जा सकता है। किसी विलगित निकाय का आवेश सदैव संरक्षित रहता है। Σq i = नियत,           यहां q i = iवे कण का आवेश आवेश के गुण स्थिर विद्युत आव...
