Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

to a garden (let alone the beach) their streets are full of cars; school playgrounds are usually flat‚ sterile areas of concrete which offer no interest or little opportunity for interaction.” The consequences of this according to his theory of Compound Flexibility is that children who have little control over the world inevitably have fewer positive experiences‚ which in turn slows the development of their self confidence. Loose-parts theory has also been referred to by Bob Hughes in his elucidation

Characterization is the process by which the author brings a character to life. Sir Arthur Conan Doyle uses exceptional characterization throughout the novel The Hound of the Baskervilles. There are four methods of characterization which can be revealed through direct characterization and indirect characterization. The most common method of characterization is the narrator’s direct description of a character. This is a very important method as it enables the reader to have a vivid picture in their

There are different types of Compound Interest. Interest is the amount of money earned in a saving account. * Simple Interest: Interest calculated once on the principal. * Compound Interest: Interest calculated for a given segment of time of the investment. For example‚ compounded monthly‚ means the interest is calculated each month and combined with the principal. So‚ for the next month‚ interest is earned on the interest. Continuously Compound Interest Formula P: ending

Bearing is always calculated from the north in a clockwise direction. Bearing is always a three digit numbers. Draw the following bearing of a) 0600 from A to B c) 2400 from P to Q b) 1100 from P to Q d) 3000 from X to Y. Answer the following questions. 1. The bearing of B from A is 0650. Find the bearing of A from B. 2. The bearing of Y from X is 1350. Find the bearing of X from Y. 3. The bearing of P from Q is 2200. Find the bearing of Q from P. 4.

Importance of Characterization How can introducing characters to the reader play an essential role in the story? There’s no doubt that the characters are important in fiction because the make events happen‚ so the way of introduce them to the reader surely makes a difference. Besides that‚ characters can be introduced to the reader not only by direct statements but also by what they do‚ say or think‚ by how other characters see them‚ by their names‚ by their appearance and also through dialogues

HISTROY The evolution of active magnetic bearings may be traced through the patent issued in this field. Earlier patents for magnetic suspensions can be found but are excluded here because they consist of assemblies of permanent magnets of problematic stability per Earns haw’s Theorem. Early active magnetic bearing patents were assigned to Jesse beams at the university of Virginia during World War II and are concerned with ultracentrifuges for purification of the isotopes of various elements for

B) A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact‚ for example‚ they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active magnetic bearings (AMB) from passive
