Answer:
19.5324 MPa
Explanation:
Information provided
Angle between the normal to the slip plane with tensile axis, 
Angle by slip direction with tensile axis, 
Critical resolved shear stress, 
Applied stress 
Shear stress at slip plane
hence crystal won’t yield
Applied stress, 
for crystal to yield is given by
The answer is <span>higher than.
</span><span>A sound-producing object is moving toward an observer. The sound the observer hears will have a frequency higher than that actually being produced by the object.
Why?
</span>As the source of the waves is moving toward the observer, each of the successive wave crest<span> is emitted from a position closer to the observer than the previous wave.
Thus each wave takes slightly less time to reach the observer than the previous wave. So, the time between the arrival of successive wave crests at the observer is reduced, increasing the frequency. </span>
The best place to put PFDs while you are out on your boat is at the top deck of your boat. PFDs must be placed at an area where it is easily accessible, especially in times of accidents, without any unnecessary gear or objects covering the PFDs, but it is best to wear a life jacket during the whole duration of the boat trip.
Answer:
it's acceleration points tangentially to its trajectory in the direction of its motion at the top.
cause only it's horizontal velocity acts at the top. and it will be horizontal in the direction of it's motion.
