The standard electrode extension for FCAW-S with 0.045" (1.1 mm) wire and an insulating nozzle is 1/4" to 3/8" (6 to 9.5 mm)
1/4" to 3/4" 6 to 19 mm)
1/2" to 1-1/2" (13 to 38 mm)
3/4" to 1-1/4" (19 to 32 mm)

can you make it more obvious. i can't see it properly

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
