Answer:
1) H. magnitude, 2) D. coordinates, 3) G. distance.
Explanation:
1) A vector has, by definition, both <em>magnitude</em> and direction. (Reason: Scalars have only magnitude)
2) Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as <em>coordinates</em>. (Reason: Coordinates are ordered pairs)
3) Speed differs from velocity in the same way that <em>distance</em> differs from displacement. (Reason: The distance is the magnitude of displacement)
I would say that it is Meteors, Meteorites, and comets. (METEORS may be wrong)
Answer:
the acceleration is constant
Explanation:
When stone is moving in the air then it has force of gravity on it
Since there is no other force like air friction is to be neglected
so we know that
so we will have
so the acceleration of the stone is always constant and directed vertically downwards with constant magnitude
