In the steady state 1.2 ✕ 1018 electrons per second enter bulb 1. there are 6.3 ✕ 1028 mobile electrons per cubic meter in tungsten. the cross-sectional area of the tungsten filament in bulb 1 is 1.3 ✕ 10-8 m2. the electron mobility in hot tungsten is 1.2 ✕ 10-4 (m/s)/(n/c). calculate the magnitude of the electric field inside the tungsten filament in bulb 3.

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).

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
