(i) \( A=\{2,-2,3\} \) and \( B=\{1,-4\} \)(ii) \( A=B=\{p, q\} \)(iii) \( A=\{m, n\} ; B=\phi \)2. Let \( A=\{1,2,3\} \) and \( B=\{x \mid x \) is a prime number less than 10\( \} . \) Find \( A \times B \) and \( B \times A \). |
|
Answer» We have A = {1, 2, 3} and B = { x | x is prime number less than 10 } = {2, 3, 5, 7} Now, A X B = {(1, 2), (1, 3), (1, 5), (1, 7), (2, 2), (2, 3), (2, 5), (2, 7), (3, 2), (3, 3), (3, 5), (3, 7)} And B X A = {(2, 1), (3, 1), (5, 1), (7, 1), (2, 2), (3, 2), (5, 2), (7, 2), (2, 3), (3, 3), (5, 3), (7, 3)} |

|
Answer» (i) We have A = {2, -2, 3}, B = {1, -4} A X B = {(2, 1), (2, -4), (-2, 1), (-2, -4), (3, 1), (3, -4)} A X A = {(2, 2), (2, -2), (2, 3), (-2, 2), (-2, -2), (-2, 3), (3, 2), (3, -2), (3, 3)} B X A = {(1, 2), (1, -2), (1, 3), (-4, 2), (-4, -2), (-4, 3)} (ii) We have A = B = {p, q} Then A X B = A X A = B X A (\(\because\) A = B) ⇒ A X B = A X A = B X A = {(p, p), (p, q), (q, p), (q, q)} (iii) We have A = {m , n}, B = ɸ A X B = A X ɸ A X B = {(m , m), (m, n), (n, m), (n, n)} B X A = ɸ X {m, n} = ɸ |

Answer» Phase: The phase of a vibrating particle at any instant completely specifies the state of the particle. It expresses the position and direction of motion of the particle at that instant with respect to its mean position the phase of the vibrating particle. At time t = 0 s (initial time), the phase φ = φ0 is called epoch (initial phase) where φ0 is called the angle of an epoch. |

Does the occurrence of diversity of animals on earth suggest their diverse ancestry also? Discuss this point in the light of evolution. |
| Answer» Though animals have a vast diversity in structures they probably do not have a common ancestry, because common ancestry may greatly limit the extent of diversity. As many of these diverse animals are inhabiting the same habitat, their evolution by geographical isolation and speciation is also not likely. Thus, a common ancestry for all the animals is not the likely theory. | |
