Input: Read this: The 2000 U.S. Census in the write-in response category had a code listing which standardizes the placement of various write-in responses for automatic placement within the framework of the U.S. Census's enumerated races. Whereas most responses can be distinguished as falling into one of the five enumerated races, there remains some write-in responses which fall into the "Mixture" heading which cannot be racially categorized. These include "Bi Racial, Combination, Everything, Many, Mixed, Multi National, Multiple, Several and Various".
Question: What did the 1990 census have in the write-in response category?

Output: unanswerable

When there is a potential difference across the conductors (e.g., when a capacitor is attached across a battery), an electric field develops across the dielectric, causing positive charge +Q to collect on one plate and negative charge −Q to collect on the other plate. If a battery has been attached to a capacitor for a sufficient amount of time, no current can flow through the capacitor. However, if a time-varying voltage is applied across the leads of the capacitor, a displacement current can flow.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What happens to the current when a battery has been attached to a capacitor for an adequate amount of time?
Ah, so.. no current can flow through the capacitor

QUES: The George Washington Bridge is the world's busiest motor vehicle bridge, connecting Manhattan to Bergen County, New Jersey. The Verrazano-Narrows Bridge is the longest suspension bridge in the Americas and one of the world's longest. The Brooklyn Bridge is an icon of the city itself. The towers of the Brooklyn Bridge are built of limestone, granite, and Rosendale cement, and their architectural style is neo-Gothic, with characteristic pointed arches above the passageways through the stone towers. This bridge was also the longest suspension bridge in the world from its opening until 1903, and is the first steel-wire suspension bridge.
The biggest suspension bridge in the US is what?

ANS:
The Verrazano-Narrows Bridge
