The inductive reactance is given by            XL = ωLThe capacitive reactance is given by             XC = 1ωCSo,       XLXC = ωL1ωC = ω2LC

In sodium chloride unit cell, there are four Na+ and four Cl- ions.Hence,density =  mass of atoms in a unit cellvolume of a unit cell =M2a3NAEach unit cel of NaCl4 Na- and 4 Cl- 2 ions → Z= 4  = 4 (23 + 35.5) g mol-1(6.023× 1023 mol-1) ×( 564 ×10-12cm)3 = 2.165 g cm-3

Cultural Approach to Personality:
• This approach explains personality in terms of individual ecology and cultural environment.
• Individual personality is determined by Group Economic Maintenance System.
• Personality is very much influenced by climatic conditions, availability of food, availability of employment and nature of terrain etc.
• The Economic Maintenance System determines people s economic activities, settlement patterns, social structures, a division of labour and other features like child-rearing practices.
• Individual psycho-physical system, skills, behavioural styles an

1000 mL of HCl contains 0·75 mol                                 = 0.75 x 36.5                                 = 27.375 g   25 mL of HCl contains                                         = 0.684 gThe reaction isCaCO3(s)    +   2HCl(aq)    CaCl2(aq) + CO2(g) + H2O(l)1 mol                 2 mol40+12+48          2 x 36.5 = 100 g              = 73 g?                        0.684 g    Now 73 g of HCl are required to react with 100g of CaCO3     0.684 g of HCl are required to react with

Difference between streamline motion and turbulent motion.i) It is an orderly type of motion in which the liquid flows in parallel layers while, turbulent motion is disorderly type of motion.ii) Every particle of the liquid follows the path of it s preceeding particle and travel with the same velocity in magnitude and direction whereas, the motion of particles of the liquids becomes different at different points in turbulent flow.iii) The velocity of streamline flow is less than critical velocity but, in turbulent motion the liquid moves with a velocity greater than the critical velocity of t

According to the figure(AC)2 = (AB)2 + (BC)2(AC)2 = a2 + a2 = 2a2(AD)2 = (AC)2+ (DC)2(4r)2 = 2a2 + a216r2 = 3a2Now, When Na metal crystallises in bcc unit cell with unit cell edge, a = 4.29Å We have the formula for radius,i.e,  =1.86Å
