PLEASE ANSWER BOTH QUESTION 4 AND 5
PLEASE ANSWER BOTH QUESTION 4 AND 5 - VYTL. 4. If 5. If Å is irrotational,...
Please answer question (a)
X1 - X X2 – Å a. Let X1, ..., Xn i.i.d. random variables with X; ~ N(u, o). Express the vector in the | Xn – form AX and find its mean and variance covariance matrix. Show some typical elements of the vari- ance covariance matrix. b. Refer to question (a). The sample variance is given by S2 = n11 21–1(X; – X)2, which can be ex- pressed as S2 = n1X'(I – 111')X (why?)....
orthogonal vectors
answer says 3. (5/13,12/13) and
4. (-1/5,6/5)
but i dont see why. both please!
Find a unit vector orthogonal to (12,-5). Are there any other than the one you found? 3. = (-7,8 ) , find a vector p such that u and p are orthogonal and 4. For the vectors u = (6,1) and p-11
Question 2. A primitive tetragonal crystal has lattice parameters of a=b=3 Å and c=4 Å and is placed in an x-rays powder diffraction system and irradiated with X-rays of wavelength 2.5 Å. (i) Use Bragg’s law to determine the scattering angle for the (001), (100), and (111) reflections (n=1). (ii) Is it possible in this apparatus to observe the (111) reflections from this crystal using X-rays of wavelength 5 Å.? Why not?
please answer both parts of the question.
