PLS HELP ASAP I WILL GIVE BRAINLIEST I RLLY RLLY NEED THIS :( 13. A tee-shirt cannon is used to launch tee-shirts into a crowd. If one shirt is launched with
an initial velocity of 24.4 m/s, at an angle of 19.5° above horizontal, what will be the x-
and y-components of the final velocity vector?

14. If a projectile is launched upward with a speed of 7.44 m/s, and at an angle of 40.1°
above horizontal, what is the hang time of this projectile?

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation

What ions are formed when hcl dissolves in water?

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.
