Introduction. Within a short period of time, organic-inorganic lead halide perovskites have demonstrated powerful applications in solar cells as a result of high-power conversion efficiencies now exceeding 23%, 1 unprecedented in the field of photovoltaics. The high-efficiency outputs of perovskite solar cells are attributed to their exceptional …Question. 18.

i • i = 1, j • j = 1 and i • j = 0. In 3-space, since i = [1, 0, 0], j = [0, 1, 0] and k = [0, 0, 1], we get. i • i = j • j = k • k = 1 and i • j = j • k = k • i = 0. In words, the dot product of i, j or k with itself is always 1, and the dot products of i, j and k with each other are always 0. a = i + 2 j-3 k & b = 3 i-j + 2 k. a + b = (i + 2 j-3 k) + (3 i-j + 2 k) a + b = 4 i + j-k. Again, a-b = (i + 2 j-3 k)-(3 i-j + 2 k) a-b =-2 i + 3 j-5 k. Now, (a + b). (a-b) = (4 i + j-k). (-2 i + 3 j-5 k) =-8 + 3 + 5 = 0. Since, the dot product of two vector (a + b) & (a-b) is 0. Therefore, they are perpendicular to each other & the angle ... ….

1 Answer Sorted by: 1 The cross product has to be orthogonal to both i + j i + j and i − j i − j. Let v v be this cross product. Then i + j, v = i, v + j, v = 0 i + j, v = i, v + j, v = 0 and i − j, v = i, v − j, v = 0 i − j, v = i, v − j, v = 0. What can you conclude?231: j X k = i. 312: k X i = j. But the three OTHER permutations of 1, 2, and 3 are 321, 213, 132, which are the reverse of the above, and that confirms what we should already know -- that reversing the order of a cross product gives us the OPPOSITE result: 213: j X i = -k. 321: k X j = -i. 132: i X k = -j.
