The length, breadth and height of a cuboid is 15 cm, 12 cm and 11 cm respectively. Length is reduced by 6 2/3% and breadth is increased by 8 1/3% while the height remains the same. What is the change in the total area of four side faces of the cuboid ? ( considering the rectangle formed by the length and breadth as base) किसी घनाभ की लम्बाई, चौड़ाई और ऊंचाई क्रमशः 15 cm, 12 cm तथा 11 cm है | लम्बाई को 6 2/3% घटा दिया जाता है और चौड़ाई 8 1/3% को बढ़ा दिया जाता है जबकि ऊंचाई को अपरिवर्तित रखा जाता है | घनाभ के (लम्बाई और चौड़ाई से बने आयत को आधार मानते हुए) चार पार्श्व-फलकों के कुल क्षेत्रफल में कितना परिवर्तन है?

The Young's modulus of a wire of length 2m and area of cross section 1 mm^(2) is 2 xx 10^(11) N//m^(2) . The work done in increasing its length by 2mm is

Find the (i) Net elongation rod approximately. (x xx 10^(-11)m) then x = (ii) Y_(eq) of the composite rod (x xx 0^(11) N..m^(2)) (assume A = area of cross section of each rod),. Then x = l_(1) = l(2) = 1m, F = 2N//m^(2), A = 1sq.m^(2) y_(1) = 2xx10^(11) N//m^(2)n, y_(2) = 3xx10^(11) N//m^(2) ltbr4gt
