Answer:
b
Step-by-step explanation:
Displacement and distance have different meanings. Displacement is a vector quantity and is the objects overall change in position. Distance is scalar quantity which describes how much ground an object covers during motion.
If they have covered 4 miles from a origin and we don't know the origin but we know that they start there and continue for 4 miles. It will be displacement if they started at a distance and walked a certain distance and the difference from start to finish is 4 miles. Therefore, it must be distance because we don't know the initial position and only that they walked 4 miles.
Mark is right if their starting point is a origin of a coordinate system
Answer:
<h3>The answer is 10132.5 g</h3>
Step-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of silver = 965 cm³
density = 10.5 g/cm³
The mass of silver is
mass = 965 × 10.5
We have the final answer as
<h3>10132.5 g</h3>
Hope this helps you
