Answer : The mass of 7.0 m chain is, 15.12 kg
Explanation :
As we are given that,
The weight of the chain per unit length = 2.16 kg/m
Now we have to determine the mass of chain for 7.0 m length.
As, the mass of 1 m length of chain = 2.16 kg
So, the mass of 7.0 m length of chain = [tex]\frac{7.0m}{1m}\times 2.16kg[/tex]
= 15.12 kg
Therefore, the mass of 7.0 m chain is, 15.12 kg
