1 In general, up to 9 months in a ziploc bag in an ordinary freezer, and 14 months in a deep freeze in a vacuum packed bag. After that, they beans won't make you sick; they just won't taste a s good.  Hi, I have a question about yellow squash.
This period is the reciprocal of the frequency. This is written as: T = 1/f. where T is the period and f is the frequency. The SI unit for frequency is the hertz (Hz), which is equal to 1/s, or once per second. Frequency is encountered many times in physics. A few highly important instances are listed here. All waves in physics are said to have frequency.
The time between each flash â the period T â is given by 1âf (the reciprocal of f â), i.e. 2, 1 and 0.5 seconds, respectively. The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second.It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves.n English, hertz is also used as the plural form. As an SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 10 3 Hz), MHz (megahertz, 10 6 Hz), GHz (gigahertz, 10 9 Hz) and THz (terahertz, 10 12 Hz).
