Grain Field
Uniform Electric Field; Finding Electric Field and Potential Difference?
A uniform electric field exists between two conducting plates separated by 2.8 mm. A dust grain with charge 65 nC between the plates feels a 29 N electric force.
Find the electric field.
E =
Find the potential difference between the plates.
Delta V =
For a particle in a E field the force is given by
E=F/q
so
29N/(65x10^-9)
For parallel plates, the relationship between the E field, Voltage and plate separation (d) is given by
E = V/d
V=Ed = (your answer for E)(2.8x10^-3)

Grain Hand Mill - 3 Reasons to Own One
Grain Hand Mill - 3 Reasons to Own One
Owning a grain hand mill may seem like an odd thing to consider for most families but a mill is an excellent idea. Usually a manual grain mill is small and easy to use.
Fresh is best: Fresh is best is an understatement. As in anything used for food preparation, you cannot do better than when an item is fresh. Well, flour is no different. The highly processed white flour at the local super market is of little nutritional value to your family. The flour making procedure is taking a proper grain of wheat and grinding it quickly at high heat which contributes to eliminating almost all of the nutritional benefits of whole grain flour. The product found at the local store is weeks or months old, not the ideal food ingredient.
Grind to your heart's content: Use a grain hand mill made with stainless steel burrs not stone and you can grind almost anything. Stainless steel burrs can grind and not clog up like stone mills will; this opens the door to a variety of grains and nuts that can be ground. Most good mills will let you set the kind of grind you want. From a very fine milled cake flour to a cracked grain for cereal or granola. Here is a list of potential nuts, grains and beans to mill.
Wheat (hard or soft)
Buckwheat
Rye
Oats
Millet
Popcorn Kernels
Field Corn dried
Triticale
Rice
Sorghum (Milo)
Split Peas
Chick Peas
Soybeans
Dried Pinto Beans
Dried Mung Beans
Dried Green Beans
Sunflower Seeds
Nuts and Peanuts
Flax Seed
Coffee Beans
Sesame Seeds
Emergency preparedness: While a generator and a pile of canned goods may come to mind to be best prepared for the unexpected events in our worldly lives. Natural disasters and catastrophes are a real fact of our lives. Bread is the most fundamental form of sustenance and is still the staff of life. The ability to bake a loaf for your family could, at some time in the future, be a critical component of your family responsibility. A hand grain mill can set in the pantry for years and be taken out and it will be ready to use. No plug in required.
Please feel welcome to come to foodtoolsplus.com to look at our different grain hand mills. Happy milling and fresh bread baking!
