Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10−2 cmcm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cmcm . The potential difference between the anode and cathode is 290 VV . An electron leaves the surface of the cathode with zero initial speed (vinitial=0vinitial=0). Find its speed vfinalvfinalv_final when it strikes the anode.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
