A second problem is that nominally ''twelve-volt'' power in cars fluctuates widely. The actual voltage will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5--6 volts during engine start. When used, DC to DC converters will usually compensate for small fluctuations, but reliable power may not be available without an independent battery-powered uninterruptible power supply.

For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens. For a converging lens (for example a convex lens), the focal length is positive, and is the distance at which a beam of collimated light will be focused to a single spot. For a diverging lens (for example a concave lens), the focal length is negative, and is the distance to the point from which a collimated beam appears to be diverging after passing through the lens.

OPTIONS:
- no
- yes

is the focal length of a convex lens negative?

A: no

In law, a minor is a person under a certain age, usually the age of majority, which legally demarcates childhood from adulthood. The age of majority depends upon jurisdiction and application, but it is generally 18. Minor may also be used in contexts that are unconnected to the overall age of majority. For example, the drinking age in the United States is usually 21, and younger people are sometimes called minors in the context of alcohol law, even if they are at least 18. The term underage often refers to those under the age of majority, but it may also refer to persons under a certain age limit, such as the drinking age, smoking age, age of consent, marriageable age, driving age, voting age, etc. Such age limits are often different from the age of majority.

OPTIONS:
- no
- yes

are you still considered a minor at 17?

A: yes
