An upward force is applied to a 6.0–kilogram box. this force displaces the box upward by 10.00 meters. what is the work done by
2 answers:
Answer:
The work done by the force on the box is W = 588 J
Explanation:
The work done by the force on the box can be expressed as:
where m is the mass of the box, g is the gravitational force g= and
,
are the heights of the box in at final and initial moment.
Replacing the values, you have:
that is W = 588 J

To solve this problem it is necessary to apply the law of Malus which describes the change in the Intensity of Light when it crosses a polarized surface.
Mathematically the expression is given as
Where,
= Initial Intensity
I = Final Intensity after pass through the polarizer
= Angle between the polarizer and the light
Since it is sought to reduce the intensity by half the relationship between the two intensities will be given as
Using the Malus Law we have,
Angle with respect to maximum is
Answer:
Q = 913.9 gpm
Explanation:
The Hazen Williams equation can be written as follows:
where,
P = Friction Loss per foot of pipe = = 4 x 10⁻⁴
Q = Flow Rate in gallon/min (gpm) = ?
d = pipe diameter in inches = (400 mm)(0.0393701 in/1 mm) = 15.75 in
C = roughness coefficient = 100
Therefore,
<u>Q = 913.9 gpm</u>
