Diagram-based questions: Observe the following figur and answer the following : Due to which common characterstic the animals shown in the figure belong to the same phylum ?

Two cells having unknown emfs E_1 and E_2 (E_1 > E_2) are connected in potentiometer circuit so as to assist each other. The null point is obtained at 8.125m from higher potential end. When cell E_2 is connected so as to oppose cell E_1 , the null point is obtained at 1.25m from the same end compare the emfs of two cells.

Find the simplest formula of a solid containing A and B atoms in cubic arrangement In which A occupies corner and B the centre of the faces of unit cell. If the side length is 5 Å , estimate the density of the solid assuming atomic weights of A and B as 60 and 90 , respectively.
