In determining safe speed of a vessel we must consider visibility, traffic density etc.
<h3>What is safe speed?</h3>
The safe speed of a vessel is the maximum speed the vessel can be operated to avoid hazards such as collision, damage of vessel, etc.
<h3>Factors considered when determining safe speed of vessels</h3>
In determining safe speed of a vessel we must consider the following factors such as;
- Weather condition, eg visibility
- Traffic density,
- Background light at night, etc
Thus, in determining safe speed of a vessel we must consider visibility, traffic density etc.

Answer: copper > chalk > flour > talcum powder > dry beans.
Explanation:
Density is the compactness of given object.
Basically, it is mass per volume.
copper has the most density
chalk has lesser density than copper.
flour has lesser density than copper and chalk.
talcum powder has lesser density than copper, chalk and flour.
dry beans have lesser density than copper, chalk, and flour.
So, it becomes,
copper > chalk > flour > talcum powder > dry beans.
Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
