    Naturally occurring lutetium (71 Lu) is composed of one stable isotope 175 Lu (97.41% natural abundance) and one long-lived radioisotope, 176 Lu with a half-life of 37 billion years (2.59% natural abundance).

  3. Baker percentage - Wikipedia

    en.wikipedia.org/wiki/Baker_percentage

    An ingredient's mass is obtained by multiplying the formula mass by that ingredient's true percentage; because an ingredient's true percentage is that ingredient's baker's percentage divided by the formula percentage expressed as parts per hundred, an ingredient's mass can also be obtained by multiplying the formula mass by the ingredient's ...

  4. Aspect ratio (image) - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio_(image)

    In contrast, digital projection technology typically supports vertically oriented images only at a fraction of the resolution of landscape-oriented images. For example, projecting a digital still image having a 3:2 aspect ratio on a 16:9 projector employs 84.3% of available resolution in horizontal orientation, but only 37.5% in vertical ...

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air.Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond.

  7. Resistor - Wikipedia

    en.wikipedia.org/wiki/Resistor

    The notation to state a resistor's value in a circuit diagram varies. One common scheme is the RKM code following IEC 60062.Rather than using a decimal separator, this notation uses a letter loosely associated with SI prefixes corresponding with the part's resistance.
