The tail of a vector is fixed to the origin of an x, y axis system. Originally the vector points along the +x axis. As time passes, the vector rotates counterclockwise. Describe how the sizes of the x and y components of the vector compare to the size of the original vector for the following rotational angles. (Select all that apply.)
(a) 90°
x has zero magnitude
y has zero magnitude
magnitude of x components is equal to magnitude of the original vector
magnitude of y components is equal to magnitude of the original vector

(b) 180°
x has zero magnitude
y has zero magnitude
magnitude of x components is equal to magnitude of the original vector
magnitude of y components is equal to magnitude of the original vector

(c) 270°
x has zero magnitude
y has zero magnitude
magnitude of x components is equal to magnitude of the original vector
magnitude of y components is equal to magnitude of the original vector

(d) 360°
x has zero magnitude
y has zero magnitude
magnitude of x components is equal to magnitude of the original vector
magnitude

Why are you posting under differing names? Please stop that, I have asked this of you before. You are posting homework here, no thinking, just looking for answers. Now you are again trying to post under differing names. That to me is an attempt at deception. Most quality colleges call that cheating. I have reached my limit, and I am a patient professor. Please post work, under one name, with your thinking.

With all dur respect. I think you speculating. I am not here to argue or prove my identity. Actually this is the first time I am using this site so i really don't know who you spoke to earlier.
