What is the sum of the following four vectors in unit-vector notation? For that sum, what are (b) the magnitude, (c) the angle in degrees, and (d) the angle in radians? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. vector E - 6.00 m at +0.9 radians
vector F - 5.00 m at -75 degrees
vector G - 4.00 m at 1.20 radiansvector H - 6.00 m at -210 degrees

their crystal patterns have been disrupted by stress

wavelength divides in half and speed stays the same.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
