State for the displacement whether the following situation is true or false. (a) It cannot be zero. (b) Its value is greater than the distance covered by the object. |
|
Answer» Both the statements aren't true means both the statements are falseExplanation: → The statement that is "It cannot be zero" is false because displacement is a vector quantity and vector quantity ( ) is that quantity which have both DIRECTION and MAGNITUDE. And we also KNOW that distance can't be zero but displacement can be. If the initial and FINAL positions are same then the displacement is zero. → The statement that is "Its value is greater than the distance covered by the object" is false because we know that displacement is the shortest distance between initial and final position.

Answer» हादसे या किसी और वजह से दांत हिलने लगे, आधा टूट जाए तो दांत को निकलवाने के साथ ही नया दांत तुरंत लगाया जा सकता है। ऐसी सुविधा केजीएमयू के प्रोस्थोडॉन्टिक्स विभाग में शुरू हो चुकी है।प्रोस्थोडॉन्टिक्स विभाग के डॉ.कौशल किशोर अग्रवाल बताते हैं कि पहले दांत निकालने पर घाव भरने के बाद नया दांत लगाने के लिए मरीजों को करीब छह माह बाद बुलाया जाता था। दोबारा सर्जरी करनी पड़ती थी। इस तकनीक से मरीज को खाने-पीने में अधिक दर्द होता था।अब इमीडिएट इंप्लांट टेक्नीक की मदद से दो से तीन घंटे में ही मरीजों को राहत मिल जाती है। डॉ कौशल के मुताबिक, इंप्लांट के आकार का मसूड़े में ड्रिल से रूट बनाया जाता है। इससे दांत की लंबाई और चौड़ाई पता चल जाती है।इसके बाद मसूड़े के भीतर मौजूद हड्डी के अंदर ड्रिल से तीन चार एमएम का छेद बनाया जाता है। छेद करने के बाद इंप्लांट को उसमें स्क्रू और दो टांके की मदद से टाइट कर देते हैं और कैप (नकली दांत) लगा दिया जाता है।दांत निकालने के साथ नया दांत लगाने के बाद मरीज को खाने-पीने में कोई दिक्कत नहीं होती है। इस प्रक्रिया में दो से तीन घंटे लगते हैं। डॉ. कौशल बताते हैं कि हर महीने 10 से 12 केस किए जा रहे हैं। मरीजों को कोई परेशानी नहीं हो रही है और सामान्य दांत की तरह ही नकली दांत भी चमकते रहते हैं।Download AMAR UJALA App for Breaking News in Hindi & Live UPDATES. https://www.amarujala.com/channels/downloads?tm_source=text_shareExplanation: |

5. What do you understand by the combination of errors? If P = x^alpha y^beta z^gama then, obtain expression for percentageerror in P. |
|
Answer» To MEASURE any physical quantity, we compare it with a standard (UNIT) of that quantity. No measurement is perfect as the errors INVOLVED in the process cannot be removed completely. Hence, in SPITE of our best effort, the measured value of a quantity is always somewhat different from its actual value, or TRUE value. |
