model rocket a is launched at an angle of 70° above the x axis, with an initial velocity of 40 m/s. an identical rocket b is launched under the same conditions at an angle of 90° above the x axis, also with an initial velocity of 40 m/s. which is the true statement about the horizontal distances the rockets will cover?
a. rocket a will travel farther horizontally than rocket b.
b. rocket b will travel farther horizontally than rocket a.
c. the rockets will travel the same horizontal distances but will do so in different amounts of time.
d. there is not enough information to answer this question.

Up of elements with the same number of valence electrons. vertical column in the periodic table of elements such as alkali metals or halogens. a horizontal row of elements in the periodic table. this is a characteristic of the elements in the periodic table that shows a pattern. it may increase or decrease across or down the table. periodic trend these are the highly reactive elements located in group 1 of the periodic table. these elements have one electron in their outer energy level which makes them highly reactive with water and halogens. these are the reactive elements located in group 2 of the periodic table. these elements have two electrons in their outer energy level which makes them reactive with water and halogens. alkaline earth metals these are the group 3 or d-block elements. these dense metals with high boiling points can have different oxidation states and all are solid at room temperature with the exception of mercury. transition metals this is the highly reactive family of elements with 7 valence electrons. this is an element with full valence shell, very unreactive. this is a group of elements with few valence electrons that conducts heat and electricity. one of a class of elements having properties intermediate to metals and nonmetals. this is a type of element that has many valence electrons, not a conductor.
