In a banked turn at constant altitude, the load factor is equal to 1/cosÎ¸. We can see that the load factor in straight and level flight is 1, since cos(0) = 1, and to generate sufficient lift to maintain constant altitude, the load factor must approach infinity as the bank angle approaches 90Â° and cosÎ¸ approaches zero.
What causes the attraction between ions forming an ionic bond? The attraction between ions is of opposites. Each electron is attracted to an electron of an opposite charge causing a transfer of electrons creating an ionic bond. (Wiley, 2016). d. Describe the strength of ionic bonds.
An ionic bond is a bond between ions with opposite charges. Cations (positively charged ions) cannot exist without anions (negatively charged ions). An electron released by an atom to from a cation must be accepted by another atom to form an anion. Cations and anions are formed in many chemical reactions by the transfer of one or more electrons from one element to another. Ionic bonds are formed by a strong attraction between positive and negative ions. Characteristics of Ionic compounds. Some important characteristics of ionic compounds are as follows. 1. Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions.
