A cross section is a cut through something (such as a coaxial cable ) at an angle perpendicular to its axis in order to view its interior structure. A well-known example is a cross section of a tree that shows its growth rings and tells its .....

When a charge is applied to it, it knocks a valence electron off of its parent atom. That newly free electron then knocks off a valence electron from another atom and so on. This creates a chain reaction of moving electrons called electric current .....

Statement Reason 1) In triangle ABC, BQ = QC Line joining mid-point of a side and parallel to another side bisects the remainig side. 2) < BQP = 90o                .....

Here,  Area of ∆BDC = 1/2  area of  ∆ABC  = 12cm2 . [Median bisect triangle in area] We know,   ∆BDC = 1/ 2 x base x height   or,  12cm2   = 1/2 x 8cm x DE. or, DE = .....

Here, Area of triangle DBC = 1/2 Area of ABC  [Median divides triangle into two equal areas] Therefore,  Area of triangle DBC = 1/2 x 24 = 12 cm2  Now, Area of triangle DBC = 12 .....

Given, Rectangular glass vessel of length L = 40 cm , breadth B =30 cm and height= H=  20 cm Height of water to be filled = h = 20cm - 12cm = 8cm So, volume of water required= L x B x h = 40cm x 30cm x 8cm          .....

Here,  Volume of rectangular vessel  = V1= L x B x H = 60cm x 10 cm  x 45 cm = 27000cm3 Volume of cubical vessel = V2 = [10cm]3= 1000cm3 No. of cubical vessel =N = V1/V2               .....
