If you are pulling on a box with a force of 30 N, and your friend is pushing the box in the same direction with a force of 30 N,
dmitriy555 [2]

Answer:

The box will move towards me by the additional force of 60N.

Explanation:

I am pulling the box with a force of 30N and my friend is pushing the box in the same direction with a force of 30N.

       Here two forces are exhibited in the same direction that is towards myself as a result the box will move towards me by an additional force of 30N+30N=60N.

The long-term and short-term carbon cycles are connected by the fact that some of the carbon contained in C6H12O6 (or other orga
Inga [223]

Answer:

<u>False</u>

Explanation:

  • The carbon cycle is a process which involves the flow of carbon through all of living things and life forms on Earth. The carbon cycle span over two segments: long-term and short-term, allowing for regulation of atmospheric carbon dioxide.
  • While the short term segment deals with Earth forms that are more 'fleeting' like water nd air, the long-term affects the rock which take centuries to process through completely.
  • In the short-term reservoir, carbon is stored in the atmosphere, oceans and biosphere with the ocean containing the largest amount of carbon.  The biggest player and regulator of atmospheric carbon however is the ocean, not the biosphere. It is what links the long-term segment reserves to the short-term because carbon dioxide is removed from the atmosphere and converted to fossil fuels and rocks which are components of the long-term reserves.

I hope this explanation was clear and comprehensive.

What is the most soluble salt of the following set? What is the most soluble salt of the following set?
DiKsa [7]

Answer:

(c) AgCN\ (K_{sp} =6.0\times 10^{-17})

Explanation:

The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.

So,  Given that:-

Sn(OH)_2\ (K_{sp} =1.6\times 10^{-19})

Al(OH)_3\ (K_{sp} =1.9\times 10^{-33})

AgCN\ (K_{sp} =6.0\times 10^{-17})

Fe(OH)_3\ (K_{sp} =2.6\times 10^{-39})

The salt having highest value of Ksp is AgCN. So, it is most soluble.
