Quiz trial -2 Quantum Mechanics. Superconductivity and Magnetic Materials

click here quiz trail 2

como conocer a los chicos de combate argentina In this quiz I have used mathematical equations to judge the output, in HTML its little difficult to write the math equations. These are two basic questions of the quantum mechanics.

http://diebrueder.ch/piskodral/7933 This quiz include three units of engineering physics, one is magnetic materials, second quantum mechanics, and the third one is Superconductivity.

  1. \bigtriangledown^{2}\Psi+ \frac{8\pi^{2}m}{h^{2}}\left (E-V\right )\Psi=0
  2. \bigtriangledown^{2}\Psi+ \frac{8\pi^{2}m}{h^{2}}\left (V-E\right )\Psi=0
  3. \bigtriangledown^{2}\Psi+ \frac{h^{2}}{8\pi^{2}m}\left (E-V\right )\Psi=0
  4. \left ( -\frac{h^{2}}{8\pi^{2}m}\bigtriangledown^{2}-V\right )\Psi=i\frac{h}{2\pi}\frac{\partial\Psi}{\partial t}
