... earthquake. This is due to dipole oscillations with the beginning of micro- fracturing process. Features of the emissions are: it has nonvanishing components for VLF region ( 30 KHz 3 KHz ), ELF region ( 3 KHz - 3 Hz) ,ULF region ( < 3 Hz ). Experimental evidence of EME before the fracture and at th ...

... 9) In a hydrogen atom, the ionization energy is defined as the energy required to move the electron from the lowest energy (ground) state to infinity. If, in the ground state, the electron is an average distance of 1.5a0, where ao=0.5x10-10m, from the proton, what is the ionization energy of the hyd ...

... A motor has coils with a resistance of 30 Ω and operates from a voltage of 240 V. When the motor is operating at its maximum speed, the back emf is 145 V. Find the current in the coils (a) when the motor is first turned on and (b) when the motor has reached maximum speed. (c) If the current in the m ...

... Note that the sign of the power flips and that during the period A the power is positive since both current and electric are potential and energy is transported from the function generator to the inductor. During the 2nd interval (B) the voltage is negative and the current still positive, so the pow ...
