Answer:
there are conversion scales used for doing that
to convert Celsius to Fahrenheit we use the formula,
T(°F) = T(°C) × 9/5 + 32
and to convert Fahrenheit to Celsius we use,
T(°F) = T(°C) × 5/9 + 32

Explanation:
Answer:
Option B is correct.
Explanation:
The resistance of a material or wire is represented by the formula below.
R=(ρL)/A
where
- R is resistance of wire
- ρ is the resistivity of the material
- A is the cross sectional area of wire
- L is length of wire
Resistance increases with increase in length and resistivity which means options C and D are wrong.
A=(π
)/4
An increase in diameter will result in a proportional increase in area
From the resistance formula, an increase in area will cause a reduction in the resistance of the material.Thus increased diameter of wire will lower the resistance of wire. Option B is correct
Have a great day
