An object is attached to a spring that is stretched and released. The equation d--Ecos( 8 ) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. Approximately when will the
object be 6 inches above the rest position? Round to the nearest hundredth, if necessary.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
