Answer:
Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
Answer:
Ionic compound
Explanation:
Barium Chloride is an ionic compound of barium and chlorine.
Barium is a metal with two valence electrons while chlorine is a non metal with seven valence electrons.
Barium will require two atoms of chlorine to form Barium chloride.
The reaction can be demonsated in the equation below.
Ba2+ + Cl- -----------> BaCl2
In this type of bond, Barium uses its 2 valence electrons to form an ionic bond with 7 valence electrons of chlorine. Chlorine will require its own two atoms to form this type of bond with Barium.
Cl -Ba-Cl = BaCl2
Answer:
True, protons are positively charged, while electrons are negatively charged, therefore they attract each other.
Explanation:
The position of the object with respect to the ground is 8.48 m
The given parameters;
height of the building, h = 24 m
time of motion, t = 1.78 s
The distance traveled by the object after 1.78 s is calculated as;
![y = v_0t + \frac{1}{2} gt^2\\\\y = 0 + 0.5 \times 9.8\times 1.78^2\\\\\y = 15.52 \ m](https://tex.z-dn.net/?f=y%20%3D%20v_0t%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20gt%5E2%5C%5C%5C%5Cy%20%3D%200%20%2B%200.5%20%5Ctimes%209.8%5Ctimes%201.78%5E2%5C%5C%5C%5C%5Cy%20%3D%2015.52%20%5C%20m)
The position of the object with respect to the ground is calculated as;
![h = 24 \ m - 15.52 \ m \\\\ h = 8.48 \ m](https://tex.z-dn.net/?f=h%20%3D%2024%20%5C%20m%20-%2015.52%20%5C%20m%20%5C%5C%5C%5C%20h%20%3D%208.48%20%5C%20m)
Thus, the position of the object with respect to the ground is 8.48 m
