A simple mass spectrometer may include an electron ionization (EI) source and magnetic sector mass analyzer. In this type of instrument, singly charged ions are produced and accelerated through the slit to the analyzer by applying hig potentials to accelerator plates. If an ion with mass 339 amu and charge z = 1 is accelerated by a potential of 6500 V, what is its kinetic energy (in J)? Note: The following information may be useful for solving the two parts of this problem. 1 amu = 1.66 x 10-27 kg Electronic charge, e = 1.602 x 10-19 C 1J = 1 kg m?/s2 1 V = 1 J/C 1.04x10-15 ) You are correct. What is the velocity of the ion?

1 eV – is the energy, which an particle with elementary charge gets going through 1V voltage. Find relation between energy in eV and J

Derive Coulomb law (that includes rho) from Maxwell equations.

Find the potential difference through which electrons must be accelerated (as in an electron microscope, for example) if we wish to resolve a virus of diameter 12 nm

Al aproximarse un tren a la estacion por una via recta la velocidad es de (-15i-18j)m/s en ese momento el maquinista desconecta la locomotora produciendo una desaceleracion de modulo 0,5m/s2. determinar el desplazamiento del tren hasta su parada la distancia recorrida el tiempo empleado la velocidad media la rapidez media When a train approaches the station on a straight track, the speed is (-15i-18j) m / s at that moment the driver disconnects the locomotive producing a deceleration of modulus 0.5m/s2 . determine the displacement of the train to its stop the distance traveled the time spent average speed
