141014 A rubber cord of density d, Young's modulus $Y$ and length $L$ is suspended vertically. If the cord extends by a length $0.5 \mathrm{~L}$ under its own weight, then $L$ is

141015 One end of a long metallic wire of length $L$, area of cross-section $A$ and Young's modulus $Y$ is tied to the ceiling. The other end is tied to a massless spring of force constant $k$ and mass $m$ is hung from the free end of the spring. If $m$ is slightly pulled down and released, then its time period of oscillation is

141017 In a tensile test on a metal bar of diameter $0.015 \mathrm{~m}$ and length $0.2 \mathrm{~m}$, the relation between the load and elongation within the proportional limit is found to be $F=97.2 \times 10^{6}(\Delta L)$, where $F$ is the load (in $N$ ) and $\Delta L$ is the elongation (in $m)$. The Young's modulus of the material in GPa is
