Both respiration and combustion can produce carbon dioxide. Therefore, of the answers in your list only the third one is correct.
Answer:
Meaning, Advantages & Disadvantages of - Osmosis, Multiflash Distillatiob
Explanation:
- Osmosis is movement of solvent (like water) through semi permeable membrane (like living cell) into solution of higher solute concentration.
Advantages - It assists equalising concentration of solute on two sides of membrane. Reverse Osmosis is used for efficient water softening, it is easy to maintain.
Disadvantages - It needs a lot of energy. A lot of pressure is required for deionisation. Water acidity level increases, as minerals get deionised.
- Multistage flash distillation refers to desalination water distilling seawater, by flashing water portions in steams in various stages of concurrent heat exchangers.
Advantages - Its Cost efficient , distillation uses waste heat. It has High gain output ratio. Quality of feedwater is less significant, compared to reverse osmosis.
Disadvantages - It has high operating cost in case of waste heat unavailability. High temperature imply high corrosion & scale formation.
2 tablets every 6 hours. The patient will receive four doses of 2 tablets. The physician will need 8 tablets for one days treatment.
Answer:
solvent = substance that can dissolve other substances
solute = substances that are dissolved
Answer:
5.10¹¹ N/C
Explanation:
As we have a proton and a neutron, we can consider that they both have the same charge, this is:
e- = e+ = |1,6x10⁻¹⁹ C| , this number is in absolute value
Then, the formula needed to calculate the magnitude of the electric field from a charged particle is:
E= kqQ/r²
Where:
K= Coulomb constant
Q= charge
r = distance between two charges
Then:
E= 8.99x10⁹N/C²*(1.6x10⁻¹⁹C)/(5.3x10⁻¹¹m)²
E=5.12x1011 N/C
It is important that this value is a magnitude, it does not have any sign (positive or negative), for the magnetic field
