1.	A 45 kg boy whose leg bones are 5 cm2 in area and 50 cm long fall through a height of 2 m without breaking his leg bones. If the bones can stand a stress of 0.9×108 N/m2, calculate the Young's modulus for the material of the bones.(Use g=10 m/s2)
Answer» A $45 kg$ boy whose leg bones are $5 {cm}^{2}$ in area and $50 cm$ long fall through a height of $2 m$ without breaking his leg bones. If the bones can stand a stress of $0.9 \times 10^{8} {N/m}^{2}$ , calculate the Young's modulus for the material of the bones. (Use $g = 10 {m/s}^{2}$ )

suppose there is a point object in front of a plane mirror. one incident ray from this point strikes mirror and reflect. Another light ray comes from some height which is above than the pointed object, strike the mirror and reflect. but when we extend first and second reflected ray it intersect at a point. will the image of the pointed object will form there. if not, why.
