Cooking apple

A cooking apple is an apple that is used mainly for cooking rather than eating fresh. Cooking apples are larger, and can be not as much of sweet and more sour than eating varieties. Some varieties have a solid flesh that doesn't smash down too much when cooked. Only the British grow a large range of apples particularly for cooking. Some apples are double purpose, often becoming sweeter and softer under storage.

Cultivars can be separated into apples which are cooked whole in the oven and become soft and fluffy and those which keep hold of their shape. These apples are often sweet-smelling. A baked apple is one that has been parched in an oven until it has become soft. The core is generally removed and often stuffed with fruits, brown sugar, raisins, or cinnamon.

Voltage

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, uttered in volts. It measures the potential energy of an electric field to source an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.
Between two points in an electric field, such as exists in an electrical circuit, the distinction in their electrical potentials is known as the electrical potential difference. This difference is proportional to the electrostatic force that tends to drive electrons or other charge-carriers from one point to the other. Potential difference, electrical potential, and electromotive force are measured in volts, leading to the commonly used term voltage. Voltage is usually represented in equations by the symbols V, U, or E. Electrical potential difference can be thought of as the capacity to move electrical charge through a resistance. At a time in physics when the word force was used loosely, the potential difference was named the electromotive force or EMF—a term which is still used in confident contexts.

Communication

Communication can be seen as process of the spread of information governed by three levels of semiotic rules ,Syntactic, pragmatic and semantic. Therefore, communication is a kind of social interface where at least two interacting agents share a common set of signs and a common set of semiotic rules. In a simplistic model, information is sent from a sender or encoder to a receiver or decoder. In a slightly more complex form feedback links a sender to a receiver. This requires that a symbolic activity, sometimes via a language. Communication development is the development of processes enabling one to understand what others say and tell , translate sounds and symbols into meaning and learn the syntax of the language. Communication is often formed around the principles of esteem, promises and the want for social improvement.
