What is the required energy of vacancy of the metal
The number of vacancies per cubic meter of a metal at 600°C is 3.1*1025 vacancies/m3. Assume the density of this metal at the given temperature is 5.84 g/cm3 and the atomic mass is 69.72g/mol. What is the required energy of vacancy of this metal?

Two blocks A and B are connected by a cord passing over two pulleys C and D and E and F. At t = 0 block A starts moving downward from the position with a constant acceleration of 0.4 m/s2 and no initial velocity.
For a Newtonian fluid or a power law fluid flowing through a cylindrical tube of radius R, calculate the constant k in the relation gamma = kU between shear rate and reduced velocity at r = R.
Two coupled identicle pendula of mass 3 kg are oscillating, having started at rest with positions x1(0) = 0.22m and x2(0) = -0.15m. Mass 1 has Tfast = 0.5s (where Tfast is the period of the rapid oscillations) and Tbeat = 10s. a) Find the amplitud
