A resistor is connected between two parallel conducting wires. A nonferrous bar is placed across the two wires. The entire setup is placed in a uniform magnetic field. On paper, the wires are drawn horizontally and the magnetic field is out of the page. The bar is pulled to the left at a constant speed. Which direction is the current through the circuit formed by the resistor, wires, and bar?

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?

Each line (unit) on the horizontal axis represents: 5 years 10 years 20 years all of the above

The standard cell potential (e°cell) for the reaction below is +0.63 v. the cell potential for this reaction is when the concentration of zn2+ = 1.0 m and the concentration of pb2+ = 2.0 x 10-4 m. pb2+(aq) + zn(s) > zn2+(aq) + pb(s)
