In the adjacent figure m || n. A, B are any two points on m and n respectively. Let ‘C’ be an interior, point between the lines m and n. Find `angleACB`.

In the expansion of (1+a)^m+n , prove that coefficients of a^m and a^n are equal.

Water is flowing in a non viscous tube as shown in the diagram .The diameter of point A and point B are 0.5 m and 0.1 m respectively . The pressure difference between point A and B are DeltaP=0.8 m, then the rate of flow is ….. m^(3)s^(-1) .

In the adjacent figure, a line n falls on lines 1 and m such that the sum of the interior angles 1 and 2 is less than 180°, then what can you say about lines 1 and m.

There are 2n points in a plane in which m are collinear. Number of quadrilateral formed by joining these lines

If A and B are two matrices of the order 3xxmand3xxn , respectively , and m=n , then the order of matrix (5A-2B) is ……….

The slope of graph as shown in figure at points 1,2 and 3 is m_(1), m_(2) and m_(3) respectively then

In the circuit shown, the current through the 4 Omega resistors is 1 amp when the points P and M are connected to a dc voltage source. The potential difference between the points M and N is. .

If M and N are any two events, the probability that at least one of them occurs is
