The longer side of cross-section of the girder is used as depth. Why?

Does the current depend on the area of cross- section of the wire used.?

The horizontal cross-section of a cylinder is a

The vertical cross-section of a cone is

The given diagarm is a cross section

The given diagarm is a cross section

In cross section,the tracheids are:

The vertical cross section of a cylinder is…….

The cross-section of a canal is a trapezium in shape. If the canal is 10m wide at the top 6m wide at the bottom and the area of cross-section is 72m^2 determine its depth.

Why should the area of cross-section of the meter-bridge wire be uniform ? Explian
