Answer: Edge dislocation is a kind of line defect in crystal lattices. The dislocation occurs either because of the presence of an extra plane of atoms or because of the loss of half a plane of atoms in the middle of the lattice. Screw dislocation is a kind of line defect that occurs when the planes ..
Answer: These terms actually describe ideal flow which doesn’t exist. No matter what flow you take, it has a certain viscosity and friction. Even if inviscid flow isn’t viscous the effect of roughness will engage friction. ItR..

Answer: A straight up change in values like from level 5 to level 10 and holding at the higher level is a step response. A staircase pattern gets created by a series of step responses. An impulse response is a spike that does not level off at the new level it has reached. The impulse ..
Answer: In mathematics, the Weierstrass function on the real line is an example of a pathological real-valued function. It is known for being continuous everywhere but differentiable nowhere. The Weierstrass function was the first published example that challenged the notion that every continuous function is differentiable except on a set of isolated points. ItR..

Answer: It really depends on what is your definition required materials. If it includes the orbital alignment necessary for the travel or a rocket that will go fast enough so we won’t even need the alignment, then the answer is most probably yes. However, there’re still a lot of variables required for this kind of ..
