Answer:
![P=7,840\ Pa](https://tex.z-dn.net/?f=P%3D7%2C840%5C%20Pa)
Explanation:
<u>Pressure Exerted by a Column of Liquid</u>
The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:
P = ρgh
Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.
The data provided is as follows:
![\rho=1000\ Kg/m^3](https://tex.z-dn.net/?f=%5Crho%3D1000%5C%20Kg%2Fm%5E3)
![g=9.8m/s^2](https://tex.z-dn.net/?f=g%3D9.8m%2Fs%5E2)
![h=80\ cm = 0.8\ m](https://tex.z-dn.net/?f=h%3D80%5C%20cm%20%3D%200.8%5C%20m)
The pressure is:
![P = 1000\ Kg/m^3\cdot 9.8\ m/s^2 \cdot 0.8\ m](https://tex.z-dn.net/?f=P%20%3D%201000%5C%20Kg%2Fm%5E3%5Ccdot%209.8%5C%20m%2Fs%5E2%20%5Ccdot%200.8%5C%20m)
![\boxed{P=7,840\ Pa}](https://tex.z-dn.net/?f=%5Cboxed%7BP%3D7%2C840%5C%20Pa%7D)
Π = c/ f
π = 3×10^8 / 1.5×10^13
π = 3÷1.5 ×10^(8-13)
π = 2×10^-5 m
The correct answer is <span>A. Atoms combining in a solution to form a solid
What this means is that atoms bond together to form a physical presence to appear and becomes deposited in a solution in solid form. </span>
Pretty sure it’s c I think if I’m wrong I’m sorry
Answer:
r= ![\frac{1}{2}e](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7De)
Explanation:
when a sphere is inscribed in a cube , a side of the cube equals the diameter of the sphere, hence;
d = e
but d = 2r
2r =e
r= ![\frac{1}{2}e](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7De)
