The last one, the soil will become weak & unable to support plant growth
An occluded front forms when a cold front catches up with a warm front. So it would bring Sun and warmth.
Answer:
Part i)
h = 5.44 m
Part ii)
h = 3.16 m
Explanation:
Part i)
Since the ball is rolling so its total kinetic energy in this case will convert into gravitational potential energy
So we have
![\frac{1}{2}mv^2 + \frac{1}{2}I\omega^2 = mgh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7DI%5Comega%5E2%20%3D%20mgh)
here we know that for spherical shell and pure rolling conditions
![v = R \omega](https://tex.z-dn.net/?f=v%20%3D%20R%20%5Comega)
![I = \frac{2}{3}mR^2](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7B2%7D%7B3%7DmR%5E2)
![\frac{1}{2}mv^2 + \frac{1}{2}(\frac{2}{3}mR^2)(\frac{v^2}{R^2}) = mgh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B2%7D%7B3%7DmR%5E2%29%28%5Cfrac%7Bv%5E2%7D%7BR%5E2%7D%29%20%3D%20mgh)
![\frac{5}{6}mv^2 = mgh](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7Dmv%5E2%20%3D%20mgh)
![h = \frac{5v^2}{6g}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B5v%5E2%7D%7B6g%7D)
![h = \frac{5(8^2)}{6(9.81)} = 5.44 m](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B5%288%5E2%29%7D%7B6%289.81%29%7D%20%3D%205.44%20m)
Part b)
If ball is not rolling and just sliding over the hill then in that case
![\frac{1}{2}mv^2 = mgh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%3D%20mgh)
![h = \frac{v^2}{2g}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7Bv%5E2%7D%7B2g%7D)
![h = \frac{8^2}{2(9.81)} = 3.16 m](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B8%5E2%7D%7B2%289.81%29%7D%20%3D%203.16%20m)
Hello! The nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine that have created a hole in the ozone layer are the Chlorofluorocarbons (CFCs)
These are compounds developed and improved by Thomas Midgley in the late 1920s. They were used as refrigerants and aerosol propellants.
These compounds created a hole in the ozone layer by the following reactions:
CCl₃F → CCl₂F· + Cl· (In the presence of light. Radical Reaction)
Cl· + O₃ → ClO + O₂
ClO + O₃ → Cl· + O₂
The last 2 reactions can repeat in a radical mechanism and explain why these compounds are so harmful to the ozone layer.
Answer:
a) Osmolarity measures the moles of solute per liter of solution.
Explanation:
Osmolarity is defined as the number of moles of solute that contribute to the osmotic pressure, per liter of solution, of solution. That is, the measurement of the solute concentration. The prefix "osmo-" indicates the possible variation of the osmotic pressure in the cells, which will occur when the solution is introduced into the body.
