Answer»

Answer:

Quantum mechanics is the BRANCH of physics relating to the very small. ... At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at EVERYDAY sizes and speeds, cease to be useful. In classical mechanics, objects exist in a specific place at a specific time.

Explanation:

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum TECHNOLOGY, and quantum information science.

न्यूयॉर्क शहर, संयुक्त राज्य अमेरिका के पूर्वोत्तर में न्यू यॉर्क राज्य में वॉशिंगटन, डी॰ सी॰ और बोस्टन के बीच लगभग आधे रास्ते में स्थित है। हडसन नदी के मुहाने पर स्थित होने से, जोकि एक स्वाभाविक बंदरगाह की तरह कार्य करता हैं, और फिर अटलांटिक महासागर, ने शहर को एक व्यापारिक बंदरगाह के रूप में महत्वपूर्ण स्थान बना दिया। अधिकांश न्यूयॉर्क शहर लांग आइलैंड, मैनहट्टन, और स्टेटन द्वीप के तीन द्वीपों को मिला कर बनाया गया है।

हडसन नदी, हडसन घाटी के माध्यम से न्यू यॉर्क खाड़ी की ओर बहती है। न्यूयॉर्क शहर और ट्रॉय, न्यूयॉर्क के बीच नदी एक मुहाना बनती है।[3] हडसन नदी अमेरिकी राज्य न्यू जर्सी को शहर से अलग करती है। हार्लेम नदी, पूर्वी और हडसन नदियों के बीच एक और ज्वारीय जलसंयोगी, ब्रोंक्स से मैनहट्टन को अलग करती है। ब्रोंक्स नदी, जो ब्रॉन्क्स और वेस्टचेस्टर काउंटी के माध्यम से बहती है, शहर की एकमात्र, पूर्ण रूप से ताजे पानी की नदी है।[4]

शहर का कुल क्षेत्रफल 468.484 वर्ग मील (1,213.37 किमी२) है, जिसमें 302.643 वर्ग मील (783.84 किमी२) भूमि और 165.841 वर्ग मील (42 9.53 किमी२) जलक्षेत्र शामिल है।[5][6] शहर का उच्चतम बिंदु स्टैटन द्वीप पर टॉड हिल है, जो समुद्र तल से 409.8 फीट (124.9 मीटर) ऊपर है।[7]

A bullet leaves a rifle with a muzzle velocity of 521m/s . While acceleration through the barrel of the rifle, the bullet moves a distance of 0.840 m. Determine the acceleration of the bullet (assume a uniform acceleration.​

Answer»

Given :

  • Muzzle velocity of the bullet = 521 m/s

To find :

  • The acceleration of the bullet

Solution :

Assume that the INITIAL velocity of the bullet as zero (as it leaves the barrel)

Now , we have

  • v = 521 m/s
  • u = 0 m/s
  • s = 0.840 m

Applying second equation of MOTION ,

\\ {\boxed{ \bf{ {v}^{2} - u {}^{2} = 2as}}}

Here ,

  • v is final velocity
  • u is initial velocity
  • a is acceleration
  • s is distance covered

Substituting the values ,

\\ : \implies \bf \: (521 \: m {s}^{ - 1} ) {}^{2} - (0) {}^{2} = 2(a)(0.840 \: m) \\ \\ \\ : \implies \bf \: (521 \times 521) \: m {}^{2} {s}^{ - 2} - 0 = 1.68 \: m(a) \\ \\ \\ : \implies \bf \: 271441 \: m {}^{2} {s}^{ - 2} = 1.68 \: m(a) \\ \\ \\ : \implies \bf \: \frac{271441 \: m {}^{2} {s}^{ - 2} }{1.68 \: m} = a\\ \\ \\ : \implies \bf \: 161572.02 \: m {s}^{ - 2} = a \\ \\ \\ : \implies \bf \: a \approx \: 162000 \: m {s}^{ - 2} \\ \\ \\ : \implies \bf \: a \approx \: 162 \times {10}^{4} \: m {s}^{ - 2} \\ \\ \\ : \implies {\boxed {\underline{\bf \: a \approx \: 1.62 \times {10}^{5} \: m {s}^{ - 2} }}}

Hence , The Acceleration of the bullet is \sf{\bf{1.62\times\:10^{5} \: ms^{-2}}}

Explanation:

Babur

Founder of the Mughal Empire and first Emperor of the Mughal dynasty (1483-1530) (r.1526-1530)

Babur (Persian: بابر‎, romanized: Bābur, lit. 'tiger'; 14 February 1483 – 26 December 1530), born Zahīr ud-Dīn Muhammad, was the founder of the Mughal Empire and first Emperor of the Mughal dynasty (r. 1526–1530) in the Indian subcontinent. He was a descendant of Timur and Genghis Khan through his father and mother respectively.

Quick facts: Reign, Predecessor …

Of Chagatai Turkic origin, Babur was born in Andijan in the Fergana Valley (in present-day Uzbekistan): the eldest son of Umar Sheikh Mirza (1456–1494, governor of Fergana from 1469 to 1494) and a great-great grandson of Timur (1336–1405). Babur ascended the throne of Fergana in its capital Akhsikent in 1494 at the age of twelve and faced rebellion. He conquered Samarkand two years later, only to lose Fergana soon after. In his attempt to reconquer Fergana, he lost control of Samarkand. In 1501 his attempt to recapture both the regions failed when Muhammad Shaybani Khan defeated him. In 1504 he conquered Kabul, which was under the putative rule of Abdur Razaq Mirza, the infant heir of Ulugh Beg II. Babur formed a partnership with the Safavid ruler Ismail I and reconquered parts of Turkistan, including Samarkand, only to again lose it and the other newly-conquered lands to the Sheybanids.

After losing Samarkand for the third time, Babur turned his attention to INDIA. At that time, the Indo-Gangetic Plain of the Indian subcontinent was ruled by Ibrahim Lodi of the Afghan Lodi dynasty, whereas Rajputana was ruled by a Hindu Rajput Confederacy, led by Rana Sanga of Mewar. Babur defeated Ibrahim Lodi at the First Battle of PANIPAT in 1526 CE and founded the Mughal empire. He faced opposition from Rana Sanga, who at first promised to help Babur defeat Ibrahim Lodi; however he later backed out upon realising that Babur had plans to stay in India. The Rana prepared an ARMY of Rajputs and Afghans to force Babur out of India, however the Rana was defeated in the Battle of Khanwa (1527) after which he was fatally poisoned (1528) by his own men.

Babur married several times. Notable among his sons are Humayun, Kamran Mirza and Hindal Mirza. Babur died in 1530 in Agra and Humayun succeeded him. Babur was first BURIED in Agra but, as per his wishes, his remains were moved to Kabul and reburied. He ranks as a national hero in Uzbekistan and Kyrgyzstan. Many of his poems have become popular FOLK songs. He wrote the Baburnama in Chaghatai Turkic; it was translated into Persian during the reign (1556–1605) of his grandson, the Emperor Akbar.

8Distinguish between the terms mass and weight.​

Answer»

mass :

  • mass is a property of matter the mass of an OBJECT is the same everywhere .
  • can never be ZERO
  • mass does not CHANGE according to location .
  • mass is a SCALAR quantity .
  • mass may be measured using an ordinary balance

weight :

  • it does depends on the EFFECT of gravity .increases or decreases with higher or lower Gravity .
  • can be zero if no gravity acts upon an object as in space .
  • weight varies according to location .
  • weight is a vector quantity
  • weight is measured by using the spring balance

Thefactor on which accelerationProduced in a body when aforce .acts at it, depends​

Answer»

Answer:

MASS &magnitude of the force applied on that body

Explanation:

Newton OBSERVED that the acceleration of an object depends on the mass of the object and the SIZE of the force applied to it. STATES that the acceleration of an object increases with increased force and decreases with increased mass.

According to Newton's second law,

F=ma⇒a=F/m

For constant F, acceleration is inversely proportional to mass i.e. acceleration produced by a force depends only upon the mass of the body and for LARGER mass, acceleration will be less.
