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.
Larger units of frequency include the kilohertz (kHz) representing thousands (1,000's) of cycles per second, the megahertz (MHz) representing millions (1,000,000's) of cycles per second, and the gigahertz (GHz) representing billions (1,000,000,000's) of cycles per second.
