A) draw the stereogram of 2/m 2/m 2/m crystal class. on this stereogram take a pole of a general face (h, k,l) where the face intersects all the three (3) axes. now complete the stereogram.

b) draw the stereogram of 4/m 2/m 2/m crystal class. on this stereogram take a pole of a general face (h, k,l) where the face intersects all the three (3) axes. now complete the stereogram.

c) what is the total symmetry content of the crystal class 4/m 2/m 2/m.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
