In order to determine the rotation speed of a turntable platter it is necessary to acquire a stroboscope disc. Some platters have strobe indicators printed on the side or in the center. If your country's AC mains electricity is 60Hz, the stroboscope must be made for that frequency.
Jicama, also known as yam bean, is a round, fleshy taproot vegetable of bean family plants. Its underground starchy root is one of the popular edible tuber-vegetables grown in many parts of Central American, South Asian, Caribbean, and some Andean South American regions.
While some jicama can weigh up to 50 pounds, they're best when harvested at around five pounds. While many vegetables and fruits are common, others are not, but that doesn't mean they're not an excellent food-just unfamiliar. For one thing, jicama plants thrive in tropical regions.
