Answer: They move more slowly, causing the forces of attraction holding them together to increase, resulting in a liquid.
Explanation:
The attraction overcomes the movement of particles, and bonds form.
To solve this problem we will apply the concepts related to the gravitational force expressed in Newton's statements as the product between the constant of gravity, the two masses to study and the distance to the square that separates them. Mathematically this can be described as
![F = \frac{GmM}{d^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7BGmM%7D%7Bd%5E2%7D)
Here,
G = Gravitational constant
m = Mass 1
M =Mass 2
d = Distance between them
Replacing with our values,
![F = \frac{(6.674*10^{-11}N\cdot m^2 /kg^2)(5.0kg)(1.25kg)}{(0.140m)^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B%286.674%2A10%5E%7B-11%7DN%5Ccdot%20m%5E2%20%2Fkg%5E2%29%285.0kg%29%281.25kg%29%7D%7B%280.140m%29%5E2%7D)
![F = 2.12*10^{-8}N](https://tex.z-dn.net/?f=F%20%3D%202.12%2A10%5E%7B-8%7DN)
Therefore the force of gravity is ![2.12*10^{-8}N](https://tex.z-dn.net/?f=2.12%2A10%5E%7B-8%7DN)
Disregarding that the cities are 120 miles apart in an absolute straight line, because no road is straight,
<span>One can assume that velocity = distance / time </span>
<span>V = 200 miles / 4 Hours </span>
<span>V = 50 Miles / Hour</span>
Answer:
Ratio is 100:1
Explanation:
From hydraulic press formulas;
(F1/A1) = (F2/A2)
Applying this to the question, we can say that Force on slave cylinder (Fs) = F1 while Force on master cylinder (Fm) = F2 and their respective Areas as As and Am.
Now plugging it into the equation to obtain;
Fs/As = Fm/Am
Now, the question says the hydraulic system is designed to exert a force 100 times as big as the one put into it, thus;
Fs = 100 Fm
And so from the equation earlier, rearranging, we have,
Fs/Fm = As/Am. So, 100Fm/Fm = As/Am
So, Fm will cancel out and we have ;
As/Am = 100/1
Thus, the ratio of the area of the slave cylinder to the master cylinder is 100:1
Answer: The force of attraction that holds two molecules is a chemical bond
Explanation:
What is Chemical bonds?
Chemical bonds are forces that hold atoms together to make compounds or molecules.
Types of chemical bonds
Chemical bonds include
1.covalent,
2. polar covalent, and
3. ionic bonds.
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
