Answer:
The average density of the rod is 1.11 kg/m
Step-by-step explanation:
Linear density is given by the expression 10/(sqrt(x 1)) kg/m
x is said to be measured in meters from one end of the rod. Therefore x represents the length of the rod = 8 m
Substitute the value of x into the expression of linear density to determine the average density of the rod
Average density = 10/(sqrt(81)) = 10/9 = 1.11 kg/m
