There is much that isnt yet known in the universe.
A striking fact in the configuration of the crust is cs 1'000 n that each continent, or elevated mass of the crust, is T diametrically opposite to an ocean basin or great de 5000 0 -5000 -15000 -20 2500 -300 pression; the only partial exception being in the case of southern South America, which is antipodal to eastern Asia.
Hence the area of an ellipse whose axes are 2a and 2b is Trab; and the volume of an ellipsoid whose axes are 2a, 2b and 2c is t rabc. The area of a strip of an ellipse between two lines parallel to an axis, or the volume of the portion (frustum) of an ellipsoid between two planes parallel to a principal section, may be found in the same way.
The underwool is T to T2 in.
If its tension is T the work required to effect this increase of surface will be TdS, and the energy of the film will be increased by this amount.
