I believe the correct answer from the choices listed above is option D. <span>The process of bringing the solvent to boiling, evaporating it all away, and leaving the solute behind, is known as evaporation. Hope this answers the question. Have a nice day.</span>
Heya!!
For calculate aceleration, let's applicate second law of Newton:

⇒ Being:
→ F = Force = 12 N
→ m = Mass = 3 kg
→ a = aceleration = ?
Lets replace according formula and leave the "a" alone:



Result:
The aceleration of the object is of <u>4 m/s²</u>
Answer:
Resistance = 3.35*
Ω
Explanation:
Since resistance R = ρ
whereas 
resistivity is given for two ends. At the left end resistivity is
whereas x at the left end will be 0 as distance is zero. Thus

At the right end x will be equal to the length of the rod, so 
Thus resistance will be R = ρ
where A = π 
so,

There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of wire and nature of the material. When there is current in a conductive material, the free electrons move through the material and occasionally collide with atoms.
