Answer:
Explanation:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.
The ratio of output force to the input force is generally the mechanical advantage of the machine.
Answer:
Q = 913.9 gpm
Explanation:
The Hazen Williams equation can be written as follows:
![P = \frac{4.52\ Q^{1.85}}{C^{1.85}d^{4.87}}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B4.52%5C%20Q%5E%7B1.85%7D%7D%7BC%5E%7B1.85%7Dd%5E%7B4.87%7D%7D)
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,
![4\ x \ 10^{-4} = \frac{4.52\ Q^{1.85}}{(100)^{1.85}(15.75)^{4.87}}\\\\Q^{1.85} = \frac{4\ x \ 10^{-4}}{1.33\ x\ 10^{-9}} \\\\Q = (300384.75)^\frac{1}{1.85}](https://tex.z-dn.net/?f=4%5C%20x%20%5C%2010%5E%7B-4%7D%20%3D%20%5Cfrac%7B4.52%5C%20Q%5E%7B1.85%7D%7D%7B%28100%29%5E%7B1.85%7D%2815.75%29%5E%7B4.87%7D%7D%5C%5C%5C%5CQ%5E%7B1.85%7D%20%3D%20%5Cfrac%7B4%5C%20x%20%5C%2010%5E%7B-4%7D%7D%7B1.33%5C%20x%5C%2010%5E%7B-9%7D%7D%20%5C%5C%5C%5CQ%20%3D%20%28300384.75%29%5E%5Cfrac%7B1%7D%7B1.85%7D)

Answer:
The kinetic energy of the particle as it moves through point B is 7.9 J.
Explanation:
The kinetic energy of the particle is:
<u>Where</u>:
K: is the kinetic energy
: is the potential energy
q: is the particle's charge = 0.8 mC
ΔV: is the electric potential = 1.5 kV
Now, the kinetic energy of the particle as it moves through point B is:
![\Delta K = K_{f} - K_{i}](https://tex.z-dn.net/?f=%20%5CDelta%20K%20%3D%20K_%7Bf%7D%20-%20K_%7Bi%7D%20)
![K_{f} = \Delta K + K_{i} = 1.2 J + 6.7 J = 7.9 J](https://tex.z-dn.net/?f=%20K_%7Bf%7D%20%3D%20%5CDelta%20K%20%2B%20K_%7Bi%7D%20%3D%201.2%20J%20%2B%206.7%20J%20%3D%207.9%20J%20)
Therefore, the kinetic energy of the particle as it moves through point B is 7.9 J.
I hope it helps you!
