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.
this frequency is the resonant frequency and this is the frequency that is used to define the si second as caesium fountain clocks are improved the microwave frequency can be more finely tuned and the si second can be even more accurately defined
