The phenomenon of raising outer edge of the curved road above the inner edge is to provide necessary centripetal force to the vehicles to take a safer turn and the curved road is called Banking of Roads.
Q2. C++ is ________.
C++ _________है |
(a) an operating system/ एक ऑपरेटिंग सिस्टम
(b) a programming language/ एक प्रोग्रामिंग लैंग्वेज
Ans. (b) Elements with different atomic number but same mass number
Isotopes are chemically same and physically different. But the converse is true in isobars. That is isobars are elements, which are chemically different but physically same. So, isobars are atoms of different elements having the same atomic mass but different atomic number. Since their number of electrons is different, their chemical properties are different.
Q4. What is the reason for formation of Mirage in desert?
मरुस्थल में मरीचिका या मृगतृष्णा बनने का मुख्य कारण क्या है?
(a) Refraction of light/ प्रकाश का अपवर्तन
(b) Reflection of light/ प्रकाश का प्रतिविम्ब
(c) Total internal reflection of light/ प्रकाश का पूर्ण आतंरिक प्रतिविम्ब
(d) Both Refraction and Total internal reflection of light/ प्रकाश का अपवर्तन तथा पूर्ण आतंरिक प्रतिविम्ब दोनों
Fortran is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing. Originally developed by IBM in the 1950s for scientific and engineering applications, Fortran came to dominate this area of programming early on and has been in continuous use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics, crystallography and computational chemistry.
Q6. Which of the following bonds are weakest in nature?
Single, Double and Triple bonds are all types of covalent bonds which is formed as a result of sharing of electrons. While, in case of hydrogen bond, there is no sharing of electrons. Hydrogen Bonds are based only upon the electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Q7. The reflection formed by the plane mirror is ________________.
समतल दर्पण द्वारा बनने वाला प्रतिविम्ब ________होता है |
Crystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution. The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. A solution that has as much solid dissolved in it.
Q10. The angle between the __________and the incident ray is called the angle of incidence.
__________और आपतित किरण के बीच के कोण को आपतन कोणकहते हैं |
A file with the HTM or HTML file extension is a Hypertext Markup Language file and is the standard web page file type on the internet. Any web browser, like as Internet Explorer, Firefox, Chrome, Opera, etc., will open and properly display HTM and HTML files. In other words, opening one of these files in a browser will “decode” what the HTM or HTML file is describing.
Q12. ________ is made by mixing iron with carbon and metals like chromium, nickel and manganese.
_________लोहे में कार्बन और क्रोमियम, निकेल तथा मैंगनीज जैसी धातुयों को मिलकर बनाया जाता है |
