Calculate the mean time between collisions for a material that has the following features: • Concentration of electrons n = 2.9 x 1028 (elecnons) • Resistivity p = 8.0 × 10-8Nm Reminder: • Mass of an electron m = 9.1 x 10-31 kg • electron charge (absolute value) e = 1.6 x 10-19C Calculate the time in multiples of 10 14 s rounded off to 1 decimal place but do not include the unit. That is if you find 2.5x10 14 s, enter 2.5 as your answer.
