Density of steel 7800
Poisson’s ratio 0.32
The resultant data(velocity) = 5666.7
From this formula, we could determine the modulus of elasticity,
Theoritical value of E of steel is 200GPa, error would be

curve shift toward applied voltage because the movement of charges is determined by applied voltage(-,+). It is known that mobile charges are generated when dielectric material has the impurities such as Na ion.
The term fast interface state refers to the fact that these defects can change their charge state relatively fast in response to changes of the gate bias. As the surface potential in a

남성의 영구적 피임방법 가운데 가장 안전하고 효율적인 수단이 정관수술이다. 하지만 남자들이 정관수술을 기피하는 이유는 수술할 때 수반되는 통증과 속발할 수도 있는 수술 후 합병증이다. 그리고 이 수술을 거세개념으로 혼동하거나 수술 후 혹시 남자의 성능력이 저
Enamel
√ Hard and white substance covering the teeth
√ The hardest and most highly mineralized
√ Protects the fragile underlying parts of the teeth
√ Covers the crown and supported by dentin
Component of enamel
√ 96% of enamel : mineral, water, organic material
√ contain two unique classes of proteins amelogenins and enamelins
√ The basic unit of enamel is called
