Pure water.
A salt solution contains impurities whereas pure water will not contain any impurities.
Impurities increase the boiling point (freezing point) of a substance.
Thus, I would expect the pure water solution to freeze faster than the salt solution.
Answer: the conclusion is that
Explanation:
Answer:

Explanation:
We define our values according to the text,
R= Radius
Velocity
Strenght of the vortex filament
From this and in a vectorial way we express an elemental lenght of this filmaent as
. So,

Where
imply a vector acting perpendicular to both vectors.
Applying Biot-Savart law, we have,

Substituting the preoviusly equation obtained,



So we can express the velocity induced is,

Answer:
0.281 m
Explanation:
Applying,
W = 0.5ke².................. Equation 1
Where W = Workdone by the stretched spring, k = spring constant, e = extension/ compression of the spring
make e the subject of the equation
e = √(2W/k)................ Equation 2
From the question,
Given: W = 1.240J, k = 31.50 N/m
Substitute these values into equation 2
e = √(2×1.240/31.50)
e = √(0.07873)
e = 0.281 m
So Force=Mass*Acceleration
You have a mass of .175 kg or 175 grams
Force= (175 g)(50)= 8750 N of force
