Question: State archimedes principle and explain it with example?

Archimedes' principle states that an object submerged in a fluid experiences an upward buoyant force that is equal in magnitude to the weight of the displaced fluid. In other words, the buoyant force exerted on an object is equal to the weight of the fluid that the object displaces.


For example, if a piece of iron with a weight of 10 N is placed in water, the iron will displace a certain volume of water equal to its own volume. If the weight of the displaced water is 8 N, then the iron will experience an upward buoyant force of 8 N, which is equal to the weight of the water displaced. This buoyant force reduces the apparent weight of the iron to 2 N while it is submerged in water.


Archimedes' principle explains why objects with a density less than that of the fluid in which they are submerged will float, while objects with a density greater than the fluid will sink. For example, a wooden block floats on water because its density is less than that of water, while a rock sinks because its density is greater than that of water. This principle is important in fields such as ship design, where it is used to determine the buoyancy of a vessel, and in the design of submarines and other underwater vehicles.

अज्ञेय का वैवाहिक जीवन उतार-चढ़ाव भरा था, वर्णन कीजिए? Aage ka vaivahik jivan utar chadhav bhara tha varnan kijiye

सवाल: अज्ञेय का वैवाहिक जीवन उतार-चढ़ाव भरा था, वर्णन कीजिए? अज्ञेय का वैवाहिक जीवन उतार-चढ़ाव भरा था। उन्होंने दो विवाह किए, लेकिन दोनों विवाह सफल नहीं हो पाए। उनका पहला विवाह 1937 में राजकुमारी रत्नलता से हुआ था। यह विवाह अज्ञेय के परिवार की इच्छा के विरुद्ध था। अज्ञेय के पिता हीरानंद वात्स्यायन संस्कृत के विद्वान थे और वे चाहते थे कि अज्ञेय एक योग्य विदुषी से विवाह करें। रत्नलता एक साधारण परिवार से थीं और वे संस्कृत नहीं जानती थीं। इस कारण से, अज्ञेय के परिवार वालों ने इस विवाह का विरोध किया। अज्ञेय और रत्नलता का विवाह कुछ वर्षों तक चलता रहा, लेकिन अंततः उनका तलाक हो गया। इस तलाक के कई कारण थे, जिनमें अज्ञेय की व्यस्त जीवनशैली, रत्नलता की शिक्षा और सामाजिक पृष्ठभूमि में अंतर, और अज्ञेय के परिवार का विरोध शामिल था। अज्ञेय का दूसरा विवाह 1956 में कपिला मलिक से हुआ था। कपिला एक मशहूर संगीतकार थीं और वे अज्ञेय की साहित्यिक प्रतिभा की प्रशंसक थीं। यह विवाह कुछ वर्षों तक चलता रहा, लेकिन अंततः यह भी विफल हो गया। इस विफलता के कारणों में अज्ञेय के व्यस्त जीवनशैली, कपिला की स्वतंत्रताप्रियता,...

Explain voter apathy indifference among the youth considered a challenge for south africa democracy?

Question: Explain voter apathy indifference among the youth considered a challenge for south africa democracy?  Voter apathy and indifference among the youth pose significant challenges to South Africa's democracy. When young people disengage from the electoral process, it undermines the representativeness and legitimacy of the government. Low youth voter turnout means that the voices and concerns of young South Africans are underrepresented in policymaking, leading to policies that may not adequately address issues crucial to them, such as unemployment, education, and access to healthcare. This lack of participation can also empower special interests and entrenched elites, further marginalizing young people's voices in the political process. Additionally, voter apathy among the youth can contribute to political instability, as a significant portion of the population feels unheard and unrepresented,

List four social beliefs in south africa that contribute to the high frequency of sexual assault?

Question: List four social beliefs in south africa that contribute to the high frequency of sexual assault? Four societal beliefs in South Africa that contribute to the high frequency of sexual assault include: Gender Inequality and Patriarchy – Deep-rooted patriarchal structures place men in positions of power, leading to the normalization of violence against women and reinforcing male dominance. Victim-Blaming Attitudes – Many believe that victims are responsible for the assault due to their behavior, clothing, or choices, discouraging them from reporting incidents and allowing perpetrators to act without accountability. Cultural Norms Surrounding Masculinity – Traditional views of masculinity emphasize aggression and dominance, leading some men to feel entitled to assert power over women through sexual violence. Silence and Stigma Around Sexual Violence – Many victims fear speaking out due to societal stigma, allowing abuse to go unreported and perpetrators to continue their actions...
