A FCC unit cell contains 4 O.V and 8 T.V. Nearest distance possible between O.V and T.V is [a is the edge length]

In a FCC unit cell x = distance between two nearest O.V. y = distance between two nearest T.V. z= distance between nearest O.V. and T.V. Select the correct order of distance,

For an adiabatic process the relation between V and T is given by

If volume of a regular tetrahedron of edge length k is V and shortest distance between any pair of opposite edges of same regular tetrahedron is d,then find the value of (d^(3))/(V)

Sodium metal exits in bcc unit cell .The distance between nearest sodium atoms is 0.368 nm. The edge length of the unit cell is:

An element crystallises in a face -centred cubic (fcc) unit cell with cell edge a. The distance between the centre of two nearest octahedral voids in the crystal lattice is ::

A planet is revolving in an elliptical orbit around the sun. Its closest distance from the sun is r and the farthest distance is R. If the velocity of the planet nearest to the sun be v and that farthest away from the sun be V. then v/V is
