If coefficient of a^2 b^3 c^4 in(a+b+c)^m (where n in N ) is L(L != 0), then in same expansion coefficient of a^4b^4c^1 will be (A) L (B) L/3 (C) (mL)/4 (D) L/2
Consider the lines L_(1) : x/3 +y/4 = 1 , L_(2) : x/4 +y/3 =1, L_(3) : x/3 +y/4 = 2 and L_(4) : x/4 + y/3 = 2 .Find the relation between these lines.
A piece of wire of length 4L is bent at random, to form a rectangle. The probability that its area is at most L^2/4 is :
The combined equation of the lines L_(1) and L_(2) is 2x^(2)+6xy+y^(2)=0 and that lines L_(3) and L_(4) is 4x^(2)+18xy+y^(2)=0 . If the angle between L_(1) and L_(4) be alpha , then the angle between L_(2) and L_(3) will be
In a laboratory four convex lenses L_(1), L_(2), L_(3) and L_(4) of focal lengths 2,4,6 and 8 cm respectively are available. Two of these lenses form a telescope of length 10 cm and magnifying power 4 . The objective and eye lenses are
On carrying out the electrolysis of acidified water, the volume of hydrogen liberated at STP condition is 22.4L . The volume of oxygen liberated is a.22.4 L b.44.8 L c.11.2 L d.2.24 L
A rod of length L is pivoted at one end and is rotated with as uniform angular velocity in a horizontal plane. Let T_1 and T_2 be the tensions at the points L/4 and 3L/4 away from the pivoted ends.
