Answer:
778.4°C
Explanation:
I = 700
R = 6x10⁻⁴
we first calculate the rate of heat that is being transferred by the current
q = I²R
q = 700²(6x10⁻⁴)
= 490000x0.0006
= 294 W/M
we calculate the surface temperature
Ts = T∞ + 
Ts = 


The surface temperature is therefore 778.4°C if the cable is bare
Answer:
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
Explanation:
Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.
Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)
Knowing this, the measures of each block are.
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
