Both the Sun and the Earth are sources of heat that power an interconnected set of dynamic systems (lithosphere, hydrosphere & cryosphere, atmosphere, biosphere).
Within the Sun, heat is transferred by radiation and convection, which involves circulation of hydrogen ions. Within the Earth heat is transferred by conduction and convection, which involves circulation of silicates in the mantle and the crust, and by the circulation of iron in the liquid outer core. On the surface of the Earth and the atmosphere, heat emanating largely from the Sun is transferred by convection, which involving the circulation of water and carbon. Both the Sun and the Earth and their atmospheres are layered. Both systems evolve and change.
In a number with decimal, zeroes to the right of last non-zero digit are significant.
Hence there are 4 significant digits in 3.140.
Hope this helps, have a great day ahead!
Answer:
Therefore, the number of grams of salt in the tank at time t is 
Explanation:
Given:
Tank A contain
lit
Rate 
Dissolved salt
gm
Salt pumped in one minute is 
Salt pumped out is
of initial amount added salt.
To find 



Solving above equation,




Integrating on both side,

Add
on above equation,

Here given in question,


Put value of constant in above equation, and find the number of grams of salt in the tank at time t.

Therefore, the number of grams of salt in the tank at time t is 
The type of the bond is present Na₃PO₄ is the ionic bond. the Na₃PO₄ is the ionic compound. yes the Na₃PO₄ is the polyatomic ion.
The Na₃PO₄ is Na⁺ and PO₄³⁻. the phosphorus is the non metal and the oxygen atom is the non metal. the non meta and non meta form the covalent or molecular bond. the bond between the PO₄³⁻ bond is the covalent bond but the overall present in the Na₃PO₄ is the ionic bond . the bons in between the Na⁺ and PO₄³⁻ is the the ionic bond. the PO₄³⁻ id the polyatomic ion .
The bond between the positively charged ion and the negatively charged ion are called as the ionic bond and the compound form is the ionic compound.

I believe the correct answer from the choices listed above is option 4. The 3 isomers of pentane have different structural formulas. <span>An </span>isomer<span> is a molecule with the same molecular formula as another molecule, but with a different chemical structure. Hope this answers the question.</span>
