`R_(3)`-এ বর্তমান

A molecule is R_(3)C-H . If H is replaced by A (R_(3)C-A) and on doing so electron density on R_(3)C part increases, then A is :

There are three relations R_(1) , R_(2) and R_(3) such that R_(1) = {(2,1),(3,1),(4,2)} , R_(2) = {(2,2),(2,4),(3,3),(4,4)} and R_(3) = {(1,2),(2,3),(3,4),(4,5),(5,6),(6,7)} then

Test whether,R_(3) on R defined by (a,b)in R_(3)a^(2)-4ab+3b^(2)=0

Let for A=[(1,0,0),(2,1,0),(3,2,1)] , there be three row matrices R_(1), R_(2) and R_(3) , satifying the relations, R_(1)A=[(1,0,0)], R_(2)A=[(2,3,0)] and R_(3)A=[(2,3,1)] . If B is square matrix of order 3 with rows R_(1), R_(2) and R_(3) in order, then The value of det. (2A^(100) B^(3)-A^(99) B^(4)) is

Find the currents in the Y connection of 3 resistances R_(1) = 10Omega , R_(2)=20Omega and R_(3)= 30 Omega . When the terminals of R_(1) , R_(3) and R_(3) are maintained at potentials V_(1) = 10V, V_(2) =6V and V_(3) = 15V.

Statement-1: ln !ABC,r_(1)+r_(2)+r_(3)-r=4R Statement-2: In !ABC,r_(1)r_(2)+r_(2)r_(3)+r_(3)r_(1)=!^(2)

In triangle ABC,(r_(1)+r_(2)+r_(3)-r) is equal to

In a DeltaABC, r_(1) + r_(2) + r_(3) -r =

In the situation shown, resistance R_(1),R_(2) and R_(3) are in the ratio 3:2:1 , then
