(a) For a thin prism, D = (μ – 1) A Since λb < λr ⇒ μr < μb ⇒ D1 < D2

(a) A hen has two legs whereas a cow has four legs.  But both of them have one head each. Let Kishan have x cows  Number of hens = 59 – x.  According...

(e) x + y = 23 and  xy = 126 Now x2 + y2 = (x + y)2 – 2xy (23)2 – 2 × 126 529 – 252 x2 + y2 = 277

(e) According to the question, 65/100 × Total votes = 520 Total votes = 520 x100/65 = 800

(b) In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. The wiring...

Be forms covalent compounds.
