An aeroplaIn aeroplane lands with a velocity of 270 km/hr and comes to rest after covering a run way o1000 m. Calculate the retardation of aeroplaneA) 2.8125m/s2B ) 3.8125 m/s C) 4.2185 m/s D) 3.2185 m/s2 |
|
Answer» Initial velocity, u = 270km/h or 75m/s Final velocity, V = 0 km/h or 0m/s { because the plane comes to rest } Distance COVERED, s = 1000m We know, ➜ 2as = v² - u² ☛ 2×a×1000 = 0 - 75² ☛ 2000a = -5625 ☛ a = -5625/2000 ☛ a = -2.8125 Hence, The RETARDATION of the plane is 2.8125 m/s² |

Hello prove thatif momentum is not always constantly as.... Snell lawrehan |
|
Answer» Answer: Momentum is always considered as only the perpendicular component having an effect. Same when billiard ball COLLIDE. The reason is understood from SIMPLE classical mechanics :- during a collision a normal force always is created always being perpendicular to the SURFACE (to the contact point). so only perpendicular acceleration can happen meaning only the perpendicular component of u can be altered.

What separation technique did Bharat expect to see at the oil refinery? What is the most important condition for this particular technique to be implemented? Give two examples of components that are separated in an oil refinery.What is the ideal location of an oil refinery in a city? Name the technique in which immiscible liquids are separated. |
|
Answer» ONG>Answer: Explanation:Not all coalescers provide a high QUANTITATIVE removal of dispersed liquid contaminants and can handle emulsions with LOW interfacial tensions (IFTs). For example, conventional cartridge coalescers made of GLASS fiber media begin to lose efficiency when the IFT of the emulsion gets below 20 dyne/cm.
Introducing Pall AquaSep® Series Liquid/Liquid Coalescers
The new AquaSep Series coalescers utilize a high-efficiency, polymeric medium, making it well suited for numerous liquid/liquid separation applications with very low IFTs. Download the guide to learn how AquaSep coalescers can help improve your process.
Advantages
• 60% more flow than before • Continuous service applications • As low as 15ppmv free water • Coarse grade for dirty flows • Great CAPEX • Low OPEX |

Rights and duties guarantees the citizens a better life |
|
Answer» ong>Answer: Fundamental duties” and “anti-national activities” came into the world fused at the hip. And while Indira Gandhi’s Emergency regime has long been consigned to the dustbin of history, its legacies endure. “Anti-national” has become a boundlessly manipulable word, that, in the spirit of Humpty Dumpty, can mean whatever those in power want it to mean. “Fundamental duties” have been making a comeback as well: at an International JUDICIAL Conference 2020 this weekend, the Chief Justice of INDIA, S.A. Bobde, drew attention to the Constitution’s Fundamental Duties chapter. He then went further, and citing Gandhi’s HIND Swaraj, observed that “real rights are a result of [the] performance of duty.” There is, of course, an intuitive plausibility to the CJI’s words. They CONJURE up the image of the ungrateful and selfish citizen, happy to pluck the fruits of civilisation, but UNWILLING to do their bit to water the tree. Nonetheless, despite its plausibility, this conflation of rights and duties ought to be resisted. Explanation: HOPE IT HELPS.... |

Calculate the number of images formed by two plane mirrors placed at an angle of 30 degree to each other. State any two applications of multiple reflection. |
|
Answer» ong>Answer: If the image of an object is VIEWED in two plane mirrors that are inclined to each other more than ONE image is formed. The number of images depends on the ANGLE between the two mirrors. The number of images formed in two plane mirrors inclined at an angle A to each other is given by the below formula.Number of images n= 360/A - 1 The number of images formed n=(360/A)-1, if (360/A) is even integer.If (360/A) is odd integer, the number of images formed n=(360/A)-1 when the object is KEPT symmetrically, and n=(360/A) when object is kept asymmetrically. If (360/A) is a fraction, the number of images formed is equal to its INTEGRAL part. As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images. Here, the angle A between the mirrors is 40 degrees. Case (a): The object is symmetrically placed. The number of images formed = (360/40)-1, we get 8 images. Case (b): The object is asymmetrically placed. The number of images formed = (360/40), we get 9 images. Hence, the number of images formed are 8 and 9 respectively. |
