Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
The way in which you need to solve this is by using the formula:
<span>R = ρL/A
</span>That one is the formula that demonstrates <span>Resistance of a wire in Ω.
The formula can be explained like this:
</span><span>ρ is resistivity of the material in Ω-m </span>
<span>L is length in meters </span>
<span>A is cross-sectional area in m² </span>
<span>A = πr², r is radius of wire in m
As soon as you have your numbers, you can replace and proceed to get the asnwer</span>
I think it’s B , carbon , nitrogen, and phosphorus
Can you show the chart please?
