What is main difference between B. E and B. TECH |
| Answer» \tCourseB.TechB.E.About the courseIt is skill orientated. B.Tech course focuses on core subjects of the branches from the very first year.It is data orientated. The curriculum is based more on theory. A B.E. student has to study subjects of other branches also. This makes people think that B.E. has more scope since the student must have knowledge of other branches as well.Duration4 years with eight semesters.4 years i.e. eight semesters in total, two per year.Eligibility10+2 with both Physics and Chemistry among the science subjects with at least 50% marks. You need to clear particular exams like\xa0JEE Mains,\xa0GUJCET, etc. for getting into certain colleges.10+2 with both Physics and Chemistry among the science subjects passed with a minimum of 50% marks. For particular colleges, you may have to crack specific entrance exams.\t | |

Prove a=ut plus 1/2atsquare by integration method |
|
Answer» (2) Second equation of motion:s = ut + 1/2 at^2sol.Let the distance travelled by the body be “s”.We know thatDistance = Average velocity X TimeAlso, Average velocity = (u+v)/2.: Distance (t) = (u+v)/2 X t …….eq.(1)Again we know that:v = u + atsubstituting this value of “v” in eq.(2), we gets = (u+u+at)/2 x t=>s = (2u+at)/2 X t=>s = (2ut+at^2)/2=>s = 2ut/2 + at^2/2or s = ut +1/2 at^2This is the 2nd equation of motion. Its not a=utIts s=ut+½at² |
