(4) Antidepressant Explanation: If the level of noradrenaline is low for some reason, then the signal-sending activity becomes low, and the person...
(1) (a) towards reactant, (b) no change Explanation: (i) As reaction is endothermic so on decrease in temperature equilibrium shift in reactant si...
Amount of CO2 in one liter of solution = 4.4. gram = 0.1 Mole pH = 1/2 {pKa - log C} For a weak acid solution pH = 1/2 { 6.4 +1 } = 3.7
(4) 2.6 m from the mirror, virtual Explanation: For I1 applying lens formula 1/v1 - 1/-1 = 1/0.5 v1 = 1 For I2 applying condition of plane m...
(3) 2 Explanation: The quality factor of LCR circuit is given by Q = ωL/R = 1/R √L/C = 1/100√(80 x 10-3/2 x 10-6) = 2

(2) 1 : 6 Explanation: 2s.png From angular momentum conservation mv1r1 = mv2r2 r1/r2 = v1/v2 = 1/6
Li = Lf 0.1 x 80 x 1 = 0.9 x (1)2/3 x ω ω = 20
1/2 mv12 = 4 - W ....(1) 1/2 mv22 = 2.5 - W ....(2) dividing and putting the value v1/v2 = 2 w = 2 eV
For this prism gives minimum angle of deviation δ = (μ - 1)A δ = (1.5 - 1) x 1° = 1/2 = 5/10 N = 5
Vrms = √3RT/M T2/T1 = M2/M1 Putting the value T2 = 41K
(1) +1V Explanation: From KVL VA + 1 + 2(1) - 2 = VB VA - VB = 1
(4) 37/3 m Explanation: s = area of graph = 1/2 x 4(1 + 13/3) - 1/2 x 2 x 5/3 = 37/3 m
(2) 5 × 102 Am2 Explanation: Magnetic moment of an iron core solenoid M = (μr - 1).NiA = (μr - 1).Ni v/ℓ = (μr - 1).Ni/ℓ iV = 999 x 10/ 10...
(1) (a)–(iv), (b) – (ii), (c) – (i), (d) – (iii)
(4) x, y and z have the same dimension. Explanation: All are dimensions of velocity.
(1) V = 0 ; E = 0 Explanation: KQnet/R Qnet = 0 So V = 0
(2) R2ω2 /2g Explanation: Both weight equally, it means effective 'g' is same for both For A gA = g. -Rω2 For B gB = g. (1 - 2h/R) gA = gB ...
(2) 3 × 10–3 A/div. Explanation: Current sensitivity = I/θ = 6 × 10–3 /2 = 3 × 10–3
(4) - bv3/(Mt) Explanation: F = V(dm/dt) a = F/M = - bv3/(Mt)
