The component of a vector r along X-axis will have maximum value if (a) r is along positive Y-axis ( … the X-axis (d) r is along…
Answers:
(d) A scalar quantity is independent of direction hence has the same value for observers with different orientations of the axes.
For example, a car is traveling along +x axis, it travels 10 m. If the same car is moving with the same speed for the same time interval along -x axis, then the distance meter of car shows the same travelled distance. The path length is same in both the cases.
