Which two wire properties would provide the greatest resistance to the flow of a current? long, thin hot, thick cool, thick
2 answers:
The quantity that measures reduce in electric current flow through the material is said to be resistance. The formula to determine the resistance is:
where R is resistance, is resistivity, L is length of the wire, and A is cross sectional are.
From the above formula it is clear that the resistance is dependent on material of the substance, length of the wire, and its cross sectional area i.e. the resistance is directly proportional to length of the wire and inversely proportional to the cross sectional area of the wire.
Hence, two wire properties that would provide the greatest resistance to the flow of a current are long and thin.

<h3>Further explanation </h3>The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
General formulas used in decay:
T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Nt=25 g
No=100 g
t1/2=5770 years
Answer: 147 mL
Explanation:
<u>Given:</u>
Molarity of the sodium bromide (NaBr) solution (M1) = 1.75 M
Volume of the solution (V1) = 84 mL
Molarity of the diluted NaBr solution (M2) = 1 M
Using the dilution formula to solve for V2:
Therefore, the new volume of the solution is 147 mL
