4. Find the work done in moving an object from (0, 0, 1) to (2, 4, 1) along the parabolic path described by y = x2,2 = 1 in the nonuniform field F = 2yaz + 2xay +za,.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
