A monochromatic light beam strikes a metallic sodium plate, whose work function is 2.28 eV. Considering Planck's constant h = 6.63 x 10^-34 J.s and the electron charge e = 1.6 x 10^-19 C, determine: 1) The maximum kinetic energy of the emitted electrons when light strikes the sodium. 2) The maximum velocity of the emitted electrons, assuming they start from rest. Consider that all the photon's energy is converted into the electron's kinetic energy and neglect interactions between the electrons and the material.Answer sheet:

An electric car was developed to be a more sustainable alternative to combustion cars, which use non-renewable resources. This car travels in a straight line, starting from an initial position of 20 meters and reaching a final position of 120 meters. Calculate the position variation (Δx) of this car during the journey.
