If it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.
<h3>What is heat transfer by convection?</h3>
Convection is the transfer of heat from one place to another due to the movement of fluid.
During heat transfer by convection, cold air replaces hot risen air.
Thus, if it takes cool air and passes it through the heat source using a fan or blower, the type of heat transfer is convection heat transfer.

I would think something like fire or a torch because that seems like it means heat or maybe a campfire picture
Answer:
1.117935:1
Explanation:
Since the wires are of the same material, they will have the same resistivity
.
The cross-sectional area of the of a wire is given by;

where d is the diameter of the wire.
Also, the relationship between resistance R, cross-sectional area A and length l of a wire is given as follows;

Since the resistivity same for both wires, say wire 1 and wire 2, we can wreite the following;

Hence from eqaution (3), the ration of wire 1 to 2 is expressed as;

Given;


We then use equation (1) to fine the ratio of the area
to 
bearing in mind that 
This ratio gives 0.8281. Substituting this into equation (5), we get the following;
