The constant forces f1 = 8 + 29 + 32 n and f2 = 48 - 59 - 22 n act together on a particle during a displacement from the point a (20, 15,0)m to the point b (0,07) m. what is the work done on the particle? the work done is given by f. f, where is the resultant force (here f = fi + f2) and is the displacement.

Aresistor with an unknown resistance is connected in parallel to a 9 ω resistor. when both resistors are connected in parallel to an emf source of 21 v, the current through the unknown resistor is measured with an ammeter to be 4 a. what is the resistance of the unknown resistor? answer in units of ω.

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?
