(i) False If P = {m, n} and Q = {n, m}, then P × Q = {(m, m), (m, n), (n, m), (n, n)} (ii) True (iii) True

(a) : From the statement given, a = 2.5 × 10–3/°C. The resistance of a wire change from 100Ω to 150Ω when the temperature is increased from 27°C to 227°C. It...

(c) Statement-1 is true, Statement-2 is true, Statement-2 is not the correct explanation of Statement-1. 

(b)  Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation of Statement-1. 

(d) : The maximum kinetic energy of the electron Kmax = hυ – hυ0 Here, υ0 is threshold frequency. The stopping potential is eV0 = Kmax = hυ – hυ0 Therefore, if υ is doubled...

(a) : The given statement r ≡ ~ p ↔ q The Statement-1 is r1 ≡ (p ∧ ~ q) ∨ (~ p ∧ q) The Statement-2 is r2 ≡ ~ (p ↔ ~...

(a) : We have adj(adj A) = |A|n–2A Here n = 2, which gives adj(adj A) = A The statement-1 is true. Again |adj A| = |A|n – 1 Here n = 2, which...

(b) : Davisson-Germer experiment showed that electron beams can undergo diffraction when passed through atomic crystals. This shows the wave nature of electrons as waves can exhibit interference and diffraction.
