SYNTHETIC FIBRES AND PLASTICS L2

If l_1=int_e^(e^2) dx/logx and l_2=int_1^2 e^x/xdx , then (A) l_1=2l_2 (B) l_1+l_2=0 (C) 2l_1=l_2 (D) l_1=l_2

Let L1 and L2 be two lines such that L_(2) : (x+1)/-3=(y-3)/2=(z+2)/1, L_(2) : x/1 = (y-7)/-3 = (z+7)/2 The point of intersection of L1 and L2 is

In a muscle fibre :

Cotton fibre is

2, 4-D is a synthetic

Store house of Ca^(+2) in muscle fibre is____

The chord of contact of tangents from a point P to a circle passes through Qdot If l_1a n dl_2 are the length of the tangents from Pa n dQ to the circle, then P Q is equal to (l_1+l_2)/2 (b) (l_1-l_2)/2 sqrt(l1 2+l2 2) (d) 2sqrt(l1 2+l2 2)

The line l_1 x+ m_1 y+n=0 and l_2 x + m_2 y+n=0 will cut the coordinate axes at concyclic points if (A) l_1 m_1 = l_2 m_2 (B) l_1 m_2 = l_2 m_1 (C) l_1 l_2 = m_1 m_2 (D) l_1 l_2 m_1 m_2 = n^2

Name 2 synthetic fibre.
