The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.
<h3>Resistance</h3>Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:
Given that R₂ = 469 ohm, hence:
But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
The equivalent resistance (R) is:

Answer:
<h2>2113 seconds</h2>Explanation:
The general decay equation is given as , then;
where;
is the fraction of the radioactive substance present = 1/16
is the decay constant
t is the time taken for decay to occur = 8,450s
Before we can find the half life of the material, we need to get the decay constant first.
Substituting the given values into the formula above, we will have;
Half life f the material is expressed as
Hence, the half life of the material is approximately 2113 seconds
