|
Answer» In a triplet STATE the EXCITED ELECTRON is no longer paired with the ground state electron; that is, they are parallel (same spin).

A rifle of 3kg fires a bullet of 100 g at initial velocity of 30m/s calculat the initial recoil |
|
Answer» Explanation: Mass of the rifle (m1) = 3 kg Mass of the bullet (m2) = 100g=0.1kg Recoil velocity of the rifle = v1 A bullet is fired with an initial velocity (v2) = 30 m/s Initially, the rifle is at rest. Thus, its initial velocity (v) = 0 The total initial momentum of the rifle and bullet system ⇒ (m1+m2) × v = 0 The total momentum of the rifle and bullet system after firing = M1V1 + m2v2 = (3 × v1 ) + (0.1 × 30) = 3v1 + 3 According to the law of conservation of momentum Total momentum after the firing = Total momentum before the firing 3v1 + 3 = 0 v1= -3/3 v1 = -1 m/s The NEGATIVE SIGN indicates that the rifle RECOILS backwards with a velocity of 1 m/s. |

द्रव्यमान संरक्षण का नियम लिखिए | किसी भी रासायनिक समीकरण को संतुलित करना क्यो आवश्यक हैं ? please no spem |
|
Answer» द्रव्यमान के संरक्षण का सिद्धांत = यह सिद्धांत कहता है कि किसी भी बंद व्यवस्था (क्लोज्ड सिस्टम) में द्रव्यमान (MASS) सदा ही संरक्षित रहता है। वह ना तो बढ़ता है और ना ही घटता है। द्रव्यमान का ना ही सृजन हो सकता है तथा ना इसे नष्ट किया जा सकता है। Explanation: समीकरण को संतुलित करना आवश्यक है क्योंकि द्रव्यमान के संरक्षण के नियम के अनुसार किसी भी रासायनिक अभिक्रिया में द्रव्यमान का न तो निर्माण होता है और न ही विनाश। इसके अनुसार दोनों तरफ़ द्रव्यमान समान होना चाहिए और वह तभी संभव है अगर दोनों तरफ़ तत्वों के परमाणुओं की संख्या समान हों। |
