Briefly explain why small-angle grain boundaries are not as effective in interfering with the slip process as are high-angle gra
artcher [175]

Answer:

Compared to High angle, relatively less presence of Crystallographic misalignment in grain boundary for small angle is reason behind its less effectiveness in interfering with slip process

Explanation:

Because of relatively much less presence of crystallographic misalignment in grain boundary for small angle, small grain boundaries are not as effective in compare to high angle in interfering with slip process

Less crystallographic misalignment in grain boundary causes not much change in slip direction and therefore interference to slip process is minimal.

SOVA2 [1]

Answer:

his movement is proportional to the intensity of the earthquake,

Explanation:

An earthquake is a record of the intensity of an earthquake as a function of time.

Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.

And the in x corresponds to time
