JEE 2021 | सरल रेखा में गति - L3 | Motion ​​in a straight line | Hindi Medium | Ravikant Sir | 7PM

A particle moving in a straight line covers half the distance with speed of 3 m//s . The other half of the distance is covered in two equal time intervals with speed of 4.5 m//s and 7.5 m//s respectively. The average speed of the particle during this motion is :

Consider a plane P passing through A(lambda,3,mu),B(-1,3,2) and C(7,5,10) and a straight line L.with positive direction cosines passing through A,bisecting BC and makes equal angles with the coordinate anes. Let L be a line parallel toL and passing through origin,Which of the following is (are) correct ?

In a triangle ABC, PQ is a straight line parallel to AC, such that Area ABC : Area PBQ = 3:1. Then CB : CQ is equal to: त्रिभुज ABC में, PQ, AC के समानांतर एक सीधी रेखा है जो इस प्रकार है कि ABC का क्षेत्रफल : PBQ का क्षेत्रफल =3 : 1 है| तो CB : CQ का मान किसके बराबर है?

A secondary alkyl halide (A) hydrolyzes with alkali (B) in aqueous medium ismultaneously via S_(N)1 and S_(N)2 pathways with rate constants k_(1) and k_(2) , respectively. form kinetic data, it was found that a plot of = (-1)/([A])(d[A])/(dt) vs [B] is straight line with a slope equal to 2.7 xx 10^(-4) L mol^(-1) min^(-1) and intercept equal to 1.02 xx 10^(-3) . Minimum initial concentration of [A] = 0.2 M and [B] , i.e., [overset(ɵ)(OH)] = 0.5 M . The value of overall rate constant of the hydrolyiss of A (in L mol^(-1) min^(-1)) is
