Answer:
1
Explanation:
Electrolysis is the passing of an current through a conducting solution, when the occurs, a chemical reaction takes place.
Heating a chemical will always cause a chemical reaction, which is why 3 is also correct
Some information as to why 2 is NOT correct.
2 is NOT a chemical reaction, but rather a process of physical separation. It uses selective boiling and condensation, but is not considered a chemical reaction.
as with 3, heating is not considered a chemical reaction, but rather a physical temperature change. This is always what it is considered to be (e.g boiling water is a physical temperature change, not a chemical reaction)

Solution :
From the Newton's second law of motion :
F = ma
Integrating above the expression by applying the limits :
Here the diameter is s= D
The final speed of the particle after travelling distance D is
The kinetic energy of the particle of mass M is :
For M = 3M
Thus the kinetic energy increases by a factor of 3.
The work done depends on the factor and the displacement of the body. Thus, the work done remains same even though the mass increases. Hence the work down increases by factor 1.
Well you would use The equation Average Speed= Distance/Time
S=4/5
S= 0.8
Answer:
temper; hot sauce
Explanation:
The context clue here is "raise the temperature slowly" gives a quick clue to <em>temper</em> (as a verb). The 4th definition of temper (as a verb) is "to bring to a suitable state by mixing or adding a usually liquid ingredient." Knowning, this leads to the second blank being <em>hot sauce</em>, as that's a liquid.
Here is your answer
REASON :
We know that
Potential difference, V= W/q
where, W is work done
and, q is magnitude of charge
Given,
V= 9.0 v and W= 45 J
So,
using above relation, we get
9= 45/q
q= 45/9
q= 5 coulomb
