Question 1 This question contains multiple parts. Make sure to read all the instructions and answer each part. Suppose we have two vectors, '5 = 35: + 41] + (71):? and 6' = 15: + (71);] + 22. Note: (in, (3,2) are equivalent to (i, 3", k). Different sources may use either convention. Part a (1 points) What is the length or magnitude of E, formally written as l| but often just u? Make sure to remember throughout our class that ALL vectors have positive magnitudes (or zero), no exceptions. Any question that asks for a vector MAGNITUDE will expect a positive answer. Only vector COMPONENTS can be negative, and components change depending on the coordinate system. You need to know the coordinate system (you need to be given a denite set of axes) to be able to give a vector component as an answer. Some questions may not explicitly say \"magnitude" in them, but if they don't give you enough information to calculate a component, then it's implied that they only want the magnitude, which is ALWAYS positive.
