Answer;
- No, Two vectors of unequal magnitude can never sum to zero.
Explanation;
-Two vectors of equal magnitude that are pointing in opposite directions will sum to zero.
-Two vectors of unequal magnitude can never sum to zero. If they point along the same line, since their magnitudes are different, the sum will not be zero.
- If they point in different directions, then you can always decompose one vector into two components: one along the other vector and one perpendicular to the other vector. In this case, the perpendicular component can never be eliminated.
A single polarizer will stop 50% of the incoming light.
No, we cannot touch gravity nor can we physically see it. We can only see how it works.
Answer:

Explanation:
The relative velocity can be calculated by means of the difference between vector B minus vector A.
