How is the voltage (electrical potential energy) of the current affected as it passes through a resistor? the voltage choose one ( increases / decreases / stays the same )

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).

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.

Aphase diagram assumes is kept constant.
