A voltage of 18 V is applied across the ends of a piece of copper wire 8 cm long. The mass of an electron is 9.11 x 10kg and its
charge is 1.6 x 10-B c What is the magnitude of the electron's acceleration? Answer in units of m/s part 2 of 2 points After traveling 4 × 10-8 m, if it does not collide with a copper ion over this distance what is the kinetic energy of the electron
Light travelling in a vacuum is the fastest thing in the universe. The speed would be 2.99x10^8 m/s. The answer to this question is 'vacuum', where light can travel the fastest. I hope this helps you. You're welcome!
