The x and y components of a vector rrightarrow are rx = 11.0 m and ry = 6.7 m, r

Question

The x and y components of a vector rrightarrow are rx = 11.0 m and ry = 6.7 m, respectively. What is the angle between the vector rrightarrow and the axis +x. degree(counterclockwise from the positive x axis) What is the magnitude of the vector rrightarrow. m If both rx and ry are doubled, how is the vector different from before? direction won't change but magnitude quadruples direction rotates counterclockwise by twice the original angle and magnitude quadruples direction rotates clockwise by twice the original angle but magnitude won't change direction won't change but magnitude doubles If rx doubled and ry remains the same, how is the vector different from before? both angle and magnitude are smaller angle is smaller and magnitude is larger both angle and magnitude are larger angle is larger and the magnitude remains the same

Explanation / Answer

a) 31.34 degrees b) magnitude = 12.879 c) direction doesnot change magnitude will change d) angel is smaller magnitude is larger
