Vector a s has a magnitude of 8.00 units and makes an angle of 45.0° with the positive x-axis. vector b s also has a magnitude of 8.00 units and is directed along the negative x-axis. using graphical methods, fi nd (a) the vector sum a s 1 b s and (b) the vector difference a s 2 b

A) First we need to decompose the vector A in x-axis and y-axis:

And also we have for vector B:

To find A + B:

B)

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
