    26) I ¹/α x² so, doubling x means I would be divided by 4. I α A² so, √(8²/4) = √16 = 4.0 μm This can also be done like this :¬ I1/ I2 = A1² / A2² 1/(1/4) = 8² /x² 4/8² = 1/x² x²= 16 x= √16 x= 4.0 μm

    First find p.d between S and P then between S and Q Formula we'll take in account is : Resistance across p.d / Total resistance * voltage Case i) - b/w S and P :¬ 5000 / 10000 * 2 = 1V1 case ii) - b/w S and Q :¬ 3000 / 5000 * 2 = 1.2V2 Now we are asked to find V1 - V2 Hence 1 - 1.2 = -0.2V = C

    21) http://www.s-cool.co.uk/a-level/phy...finitions-of-stress-strain-and-youngs-modulus We know that E is inversely proportional to the area, and directly proportional to the length. Now, when we increase the length to 3L, the extension also increases 3 times → 3x. But becoz we increase the...
