TIME SMART STUDY

QUESTION:1   Explain the fermet's Principle Fermat's principle , also known as the  principle of least time , is the link between  ray optics  and  wave optics . In its original "strong" form,  Fermat's principle states that the path taken by  a ray  between two given points is the path that can be traversed in the least time. In order to be true in all cases, this statement must be weakened by replacing the "least" time with a time that is " stationary " with respect to variations of the path — so that a deviation in the path causes, at most, a  second-order  change in the traversal time. To put it loosely, a ray path is surrounded by close paths that can be traversed in  very  close times. It  can be shown  that this technical definition corresponds to more intuitive notions of a ray, such as a line of sight or the path of a narrow beam. QUESTION:2 Find the Resultants Amplitude and Intensity of the Princip...

  QUESTION:1 WRITE A DESCRIPTION ABOUT NIGHT OF THE SCORPION   The poem “Night of the Scorpion” recounts an incident that occurred on a miserable rainy night. The poet remembers that it had been raining heavily for ten hours and a scorpion crawled beneath a sack of rice in the poet’s home to keep itself away from water. Then unfortunately the scorpion stung the poet’s mother and after biting his mother the scorpion with its diabolic tail it left the house.           It must be a rainy night in summer because we experience heavy rain only in summer. So the setting of the poem “Night of the Scorpion” is a rainy night. The encounter between the poet’s mother and the scorpion is not told in detail. We don’t know why the scorpion stung the poet’s mother. One thing is clear that the scorpion came to keep itself dry from the relentless rain, it might have stung only to protect itself. The poet’s address of the scorpion as ‘diabolic’ sugges...

QUESTION:1 WRITE ABOUT INTERNET, WITH TYPES OF CONNECTIVITY?   इंटरनेट सूचना तकनीक की सबसे आधुनिक प्रणाली है। इंटरनेट को आप विभिन्न कंप्यूटर नेटवर्को का एक विश्व स्तरीय समूह (नेटवर्क) कह सकते है। ... इंटरनेट किसी एक कंपनी या सरकार के अधीन नही होता है, अपितु इसमें बहुत से सर्वर (Server) जुड़े हैं, जो अलग अलग संस्‍थाओं या प्रायवेट कंप‍नीयों के होते हैं। Types of Connectivity :- Mobile Internet  : Telephone service provider (TSP ) इंटरनेट तक पहुंचने के लिए इंटरनेट प्लान देता है।  जो कि उपयोगकर्ता को अपने उपयोग के अनुसार खरीदना पड़ता है।  इंटरनेट को स्पीड उपयोग में लिए जा रहे सिस्टम के ऊपर निर्भर करता है।  अभी यह कम से कम 2G  तथा अधिकतम 4G की स्पीड दे सकता है।  Telephone Line   (DSL) : Digital Subscriber Line एक प्रकार का broadband connection है। जो साधारण टेलीफोन लाइन में भी इंटरनेट कनेक्शन उपलब्ध कराता है।  यह Dial -up connection से अधिक तेज गति से चलता है।  Integrated Services Digital Network (ISDN) : यह फ़ोन लाइन द्वार...

  PAPER 2nd QUESTION:1 WHAT IS DATA STRUCTURE? EXPLAIN DIFFERENT TYPES OF DATA STRUCTURE A data structure is a group of data elements grouped together under one name. These data elements, known as members, can have different types and different lengths. Data structures can be declared in C++ using the following syntax: struct type_name { member_type1 member_name1; Types Data Structures are:- 1. Arrays An array is a structure of fixed-size, which can hold items of the same data type. Arrays are indexed, meaning that random access is possible. An array is usually presented as a native data structure in many programming languages. However, one shall not confuse array with the list like data structures in languages like python. Let us see arrays are presented in C++; // simple declaration int array[] = {1, 2, 3, 4, 5 }; // in pointer form (refers to an object stored in heap) int * array = new int[5]; 2. Linked Lists A linked list is a sequential st...

  QUESTION:1 WRITE A SUMMARY NIGHT OF THE SCORPION Summary : The poem opens in a way that recommends reflection—the speaker recollects the night his  own mother was stung by a scorpion, which bit his mother as a result of its savage drive, while  stowing away underneath a sack of rice to escape from the rain. The speaker particularly recollects  this night because of this occasion, the mother getting nibbled. The manner by which the mother is  chomped is likewise appeared in ‘blaze of fiendish tail’; the speaker figures out how to propose that  the scorpion is evil with its “diabolic” tail and stresses its speed with the word streak. The scorpion at  that point escapes the scene and, in this way, hazards the rain once more. A photo of a religious town is made by what the neighbours do to deaden the scorpion  (“buzz the name of God”). Their purpose behind this is they trust that as the scorpion moves, his  toxin moves in the blood of the mothe...
