Here are two vectors:    a→=(4.0m)i^−(3.0m)j^\vec{a}=(4.0m)\rm{\hat{i}} - (3.0m)\rm{\hat{j}} b→=(6.0m)i^+(8.0m)j^\vec{b}=(6.0m)\rm{\hat{i}} + (8.0m)\rm{\hat{j}} What are (a) the magnitude and (b) the angle (relative to i^\rm{\hat{i}}) of  a→\vec{a} ? What are (c) the magnitude and (d) the angle of b→\vec{b} ? What are (e) the magnitude and (f) the angle of a→+b→\vec{a}+\vec{b} ? What are (g) the magnitude and (h) the angle of b→−a→\vec{b}-\vec{a} ? What are (i) the magnitude and (j) the angle of a→−b→\vec{a}-\vec{b} ? What is (k) the angle between the directions of  b→−a→\vec{b}-\vec{a} and  a→−b→\vec{a}-\vec{b} ? Please round your answers to zero decimal places.   (a) the magnitude of a→\vec{a} = [Fill in the blank], m (b) the angle off a→\vec{a}  = [Fill in the blank], o (c) the magnitude of b→\vec{b} = [Fill in the blank], m (d) the angle of b→\vec{b}  = [Fill in the blank], o (e) the magnitude of a→+b→\vec{a}+\vec{b} = [Fill in the blank], m (f) the angle of a→+b→\vec{a}+\vec{b}  = [Fill in the blank], o (g) the magnitude of  b→−a→\vec{b}-\vec{a} = [Fill in the blank], m (h) the angle of  b→−a→\vec{b}-\vec{a}  = [Fill in the blank], o (i) the magnitude of  a→−b→\vec{a}-\vec{b}  = [Fill in the blank], m (j) the angle of a→−b→\vec{a}-\vec{b}  = [Fill in the blank], o (k) the angle between  b→−a→\vec{b}-\vec{a} and  a→−b→\vec{a}-\vec{b}  = [Fill in the blank], o
