Answer:
The cold length of metal rod is 435.14 cm
Step-by-step explanation:
Given as :
The percentage expansion of metal rod = 3.5%
The quantity of expansion = 15.23 cm
Let the cold length be x
So, 3. 5% of x = 15.23 cm
Or, 0.035 × x = 15.23 cm
Or, x = [tex]\frac{15.23}{0.035}[/tex] cm
∴ x = 435.14 cm
Hence The cold length of metal rod is 435.14 cm Answer
