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 exists between Mg and O in MgO. As a very general rule, if a metal, like magnesium, is bonded to a nonmetal, like oxygen, the two will form an ionic bond. In an ionic bond, one or more atoms lose electrons and gain a positive charge. These are called cations. One or more atoms pick up electrons and gain a negative charge.
