Answer: D) water
Explanation: When pure hydrogen is used as the fuel, the only by-products generated from the fuel cell are pure water and heat.
Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.
The point of this question seems to be to draw your attention to the fact that vectors are incompletely specified if their directions are not stated. So adding two incompletely specified quantities cannot lead to a unique answer.
<span>You can get the idea by drawing a diagram - </span>
<span>first draw the 12m vector as a line AB in an arbitrary direction (you could equally well start with the 5m vector). </span>
<span>then, centred at one end (A) of the first vector draw a sphere of radius equal to the magnitude of the second vector. The sphere represents the 5m vector pointing in all possible directions in 3 dimensions. </span>
<span>Now the sum of the vectors is any line joining the other end (B) of the 1st vector to the surface of the sphere. Clearly the minimum length (magnitude) of the sum is 12 - 5 = 7m, while the maximum length is 12 + 5 = 17m</span>
