Problem: Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Larger capacitors like electrolytics usually display the actual capacitance together with the unit (for example, 220 μF). Smaller capacitors like ceramics, however, use a shorthand consisting of three numeric digits and a letter, where the digits indicate the capacitance in pF (calculated as XY × 10Z for digits XYZ) and the letter indicates the tolerance (J, K or M for ±5%, ±10% and ±20% respectively).
In what SI unit is the capacitance reported on smaller capacitors?
---
Answer: in pF


Problem: The bandolim (Portuguese for "mandolin") was a favourite instrument within the Portuguese bourgeoisie of the 19th century, but its rapid spread took it to other places, joining other instruments. Today you can see mandolins as part of the traditional and folk culture of Portuguese singing groups and the majority of the mandolin scene in Portugal is in Madeira Island. Madeira has over 17 active mandolin Orchestras and Tunas. The mandolin virtuoso Fabio Machado is one of Portugal's most accomplished mandolin players. The Portuguese influence brought the mandolin to Brazil.
When was the bandolim not popular among the Portugese bourgeoisie?
