Which of the following is an accurate statement about vectors? it is possible to add a scalar quantity to a vector. if two vectors have unequal magnitudes, it is possible that their vector sum is zero. rotating a vector about an axis passing through the tip of the vector does not change the vector. the magnitude of a vector can be zero even if one of its components is not zero. the magnitude of a vector may be positive even if all of its components are negative.

The magnitude of a vector may be positive even if all of its components are negative.
 In fact, the length of a vector is calculated as
 lvl = root ((a) ^ 2 + (b) ^ 2)
 Where a and b are components of the vector, both can be less than zero, however the result of the magnitude of the vector is positive.
 
 The magnitude of a vector may be positive even if all of its components are negative.

No because a circle or pie graph usually shows percentages you'd need a line graph

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
