Which one of the following statements is incorrect for HCP packing arrangement in 3D? a) The coordination no.is 12 .b)It has 74% packing efficiency. c) All the octahedral void are fully present inside the unit cell. D) All the tetrahedral void are fully present inside the unit cell.

Arrange the following stages of cell development in a correct sequence A mature cell, B-Plasmatic growth, C-meristematic cell, D-differentiation, E-cell division The correct sequence is :

In the arrangement as shown, A and B arc two cylinders each of length L and density d_1 and d_(2)(d_(1)ltd_(2)) respectively. They are joined together and submerged in the liquid of density d with length L//2 of A outside the liquid. If the difference in densities of two cylinders is equal to density of the liquid, find d_(1) .
