Answer:
The discharge rate is ![Q = 0.0192 \ m^3 /s](https://tex.z-dn.net/?f=Q%20%3D%200.0192%20%5C%20%20m%5E3%20%2Fs)
Explanation:
From the question we are told that
The diameter is ![d = 60 \ mm = 0.06 \ m](https://tex.z-dn.net/?f=d%20%3D%20%2060%20%5C%20mm%20%20%20%3D%20%200.06%20%5C%20m)
The head is ![h = 6 \ m](https://tex.z-dn.net/?f=h%20%20%3D%20%206%20%5C%20m)
The coefficient of contraction is ![Cc = 0.68](https://tex.z-dn.net/?f=Cc%20%20%3D%20%200.68)
The coefficient of velocity is ![Cv = 0.92](https://tex.z-dn.net/?f=Cv%20%20%3D%20%200.92)
The radius is mathematically evaluated as
![r = \frac{d}{2}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Cfrac%7Bd%7D%7B2%7D)
substituting values
![r = \frac{ 0.06 }{2}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Cfrac%7B%200.06%20%7D%7B2%7D)
![r = 0.03 \ m](https://tex.z-dn.net/?f=r%20%3D%20%200.03%20%5C%20m)
The area is mathematically represented as
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cpi%20r%5E2)
substituting values
![A = 3.142 * (0.03)^2](https://tex.z-dn.net/?f=A%20%3D%20%203.142%20%2A%20%20%280.03%29%5E2)
![A = 0.00283 \ m^2](https://tex.z-dn.net/?f=A%20%3D%200.00283%20%5C%20m%5E2)
The discharge rate is mathematically represented as
![Q = Cv *Cc * A * \sqrt{ 2 * g * h}](https://tex.z-dn.net/?f=Q%20%3D%20%20Cv%20%2ACc%20%20%2A%20%20A%20%20%2A%20%20%5Csqrt%7B%202%20%2A%20g%20%2A%20%20h%7D)
substituting values
![Q = 0.68 * 0.92* 0.00283 * \sqrt{ 2 * 9.8 * 6}](https://tex.z-dn.net/?f=Q%20%3D%200.68%20%2A%20%200.92%2A%20%20%200.00283%20%20%2A%20%20%5Csqrt%7B%202%20%2A%209.8%20%2A%20%206%7D)
![Q = 0.0192 \ m^3 /s](https://tex.z-dn.net/?f=Q%20%3D%200.0192%20%5C%20%20m%5E3%20%2Fs)
It would destroy animals homes shelter etc. it also would make global warming go faster. Hope this helped :D
Answer:
The car stops after 32.58 m.
Explanation:
t = Time taken for the car to stop
u = Initial velocity = 20 m/s
v = Final velocity = 0
s = Displacement
a = Acceleration = -6 m/s²
Time taken by the car to stop
![v=u+at\\\Rightarrow t=\frac{v-u}{a}\\\Rightarrow t=\frac{0-20}{-6}\\\Rightarrow t=3.33\ s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%20t%3D%5Cfrac%7Bv-u%7D%7Ba%7D%5C%5C%5CRightarrow%20t%3D%5Cfrac%7B0-20%7D%7B-6%7D%5C%5C%5CRightarrow%20t%3D3.33%5C%20s)
Total Time taken by the car to stop is 0.5+3.33 = 3.83 s
![s=ut+\frac{1}{2}at^2\\\Rightarrow s=20\times 3.83+\frac{1}{2}\times -6\times 3.83^2\\\Rightarrow s=32.58\ m](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2%5C%5C%5CRightarrow%20s%3D20%5Ctimes%203.83%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20-6%5Ctimes%203.83%5E2%5C%5C%5CRightarrow%20s%3D32.58%5C%20m)
The car stops after 32.58 m.
Distance between car and obstacle is 50-32.58 = 17.42 m
The Boiling point,melting point, surface tension and viscousity will increase while the Vapor pressure will decrease.
<h3 /><h3>What are intermolecular forces?</h3>
Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces
An increase in the strength of intermolecular forces increases will lead to an increase in force applied to break the barriers posed by the strength of the molecules.
This increased intermolecular strength will cause a rise in boiling point,melting point, viscousity and surface tension.
The Vapor pressure reduces with increasing intermolecular strength. Vapor pressure is the amount of vapor that is equilibrium with its own liquid or solid. Hence,with increasing intermolecular strength the amount of vapor that is in equilibrium with its own liquid will reduce.

The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. The positively charged fibers are now attracted to the negatively charged balloon. The negatively charged balloon attracts the paper.
