We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
<h3>How do we know that displacement and time determine velocity?</h3>
We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is 
, meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.
Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

Answer:
The answer to your question is 1.2 moles of copper
Explanation:
Data
mass of copper = 75 g
moles = ?
Process
1.- Look in the periodic table for the atomic mass of copper.
Atomic mass = 63.55 g/mol
2.- Use proportions to determine the moles of copper in 75 g
63.55 g of copper -------------------- 1 mol
75 g of copper -------------------- x
Use cross multiplication
x = (75 x 1) / 63.55
x = 75 / 63.55
x = 1.18 moles ≈ 1.2 moles of copper
