Answer:
The ratio of the diameter of iron to Cu is;
Explanation:
R=(ρL)/A
- R is resistance,
- L is length,
- A is area,
- ρ is resistivity
- d is diameter
from the question the two materials have the same resistance per unit length.
for iron = for copper
This means we can equate ρ/A for both materials.
re-arranging the equation we have,
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That's it.
