In an electron microscope, electrons are accelerated by passing them through a voltage difference. The kinetic energy thus acquired by the electrons is equal to - 19 the voltage times the charge on the electron. Thus, a voltage difference of 1 volt imparts a kinetic energy of 1.602 × 10 volt-coulomb or 1.602 × 10¯ 19 J. 1 Calculate the wavelength, in pm, associated with electrons accelerated by 5.00 × 103 volts. (KE (---) mu² = 2 Be sure your answer has the correct number of significant digits. 2 = ☐ pm x10

can you answer this again in a more understanding and easy to interpret way. Like an answer key.

Can you help me on questions 2 AND 3
