Problem: Cardinal (Catholicism):

A cardinal named in pectore is known only to the pope; not even the cardinal so named is necessarily aware of his elevation, and in any event cannot function as a cardinal while his appointment is in pectore. Today, cardinals are named in pectore to protect them or their congregations from reprisals if their identities were known.

Which cardinal is known by all the Catholic Church?

A: unanswerable


Problem: Dominican Order:

Female houses differed from male Dominican houses in a lack of apostolic work for the women. Instead, the sisters chanted the Divine Office and kept all the monastic observances. Their lives were often much more strict than their brothers' lives. The sisters had no government of their own, but lived under the authority of the general and provincial chapters of the order. They were compelled to obey all the rules and shared in all the applicable privileges of the order. Like the Priory of Dartford, all Dominican nunneries were under the jurisdiction of friars. The friars served as their confessors, priests, teachers and spiritual mentors.

How did female house not differ from male Dominican houses?

A: unanswerable


Problem: Electric motor:

Whereas SCIMs cannot turn a shaft faster than allowed by the power line frequency, universal motors can run at much higher speeds. This makes them useful for appliances such as blenders, vacuum cleaners, and hair dryers where high speed and light weight are desirable. They are also commonly used in portable power tools, such as drills, sanders, circular and jig saws, where the motor's characteristics work well. Many vacuum cleaner and weed trimmer motors exceed 10,000 rpm, while many similar miniature grinders exceed 30,000 rpm.

At around what RMP do weed trimmer motors operate?
---
A: 10,000
