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:
is the activity, measured in of a 50 mg sample of 90-Sr.
Explanation:
Half life of the 90-Sr ,
Activity coefficient of the 90-Sr =
Mass of 90-Sr = 50 mg = 0.050 g
Molecular mass of 90-Sr = 90 g/mol
Moles of 90-Sr =
Number of atom in 0.0005555 moles of 90-Sr:
1 year =
Activity measured in atoms per seconds:
= Number of atoms ×
The amount of seawater that will be displaced would be 1.3274 x
Density = mass/volume.
Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.
4247 tons of seawater = 3.8528 x g
volume of 3.8528 x g seawater = mass/density = 3.8528 x
g/1.025 = 3758829268.29 cubic centimeter.
3758829268.29 = 132741.80
or 1.3274 x
