Answer:
- Z
Explanation:
To facilitate the accompaniment of the reasoning, I copy the data here:
Object Motion
X 3 units left, 3 units right
Y 6 units right, 18 units right
W 8 units left, 24 units right
Z 16 units right, 8 units left
The <em>distance</em> is the scalar magnitude that indicates the total length of the path traveled.
The <em>displacement</em> is the vector that indicates how far the end point and the initial point are.
In order to calculate the distance, the displacement and the ratio r = distance/displacement, to check which object has a distance that is three times as great as its displacement, i.e. r = 3, we use this new chart:
Object Motion Distance Displacement ratio
X 3 units left, 3 units right 3 + 3 = 6 3 - 3 = 0 ∞
Y 6 units right, 18 units right 6 + 18 = 24 6 + 18 = 24 1
W 8 units left, 24 units right 8 + 24 = 32 -8 + 24 = 16 2
Z 16 units right, 8 units left 16 + 8 = 24 16 - 8 = 8 3
The ratios were calculated dividing the distance by the displacement: distance / displacement.
For the object Z, that was 24 / 8 = 3. Thus, the object that has a distance that is three times as great as its displacement is the object Z.

Explanation:
Hello,
In this case, is possible to infer that the thermal equilibrium is governed by the following relationship:
Thus, both iron's and water's heat capacities are: 0.444 and 4.18 J/g°C respectively, so one solves for the mass of water as shown below:
