Two vectors are given as A= 4.0i + 6.0j and B= 5.0i - 2.0j a) sketch the vectors in a diagram and find magnitude and direction of each vector

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.

What is the length x of the side of the triangle below? (hint: use the cosine function)

Which of these is the best way to manage a natural resource
