Answer:
T = 29.6 N
Explanation:
length of the rope is
L = 18 m
mass of the rope is
m = 12 kg
now we have
mass per unit length of the rope is given as
[te]\lambda = \frac{12 kg}{18 m}[/tex]
now time taken by wave to reach from end to other
now we have
so we will have
Answer: The center of gravity is 1.1338 m away from the left side of the barbell
Explanation:
Length of the barbell = 1.90 m
The distance center of gravity from left = x
Mass on the left side = 25 kg
The distance center of gravity from right = 1.90 - x
Mass on the right side = 37 kg
At the balance point:
The center of gravity is 1.1338 m away from the left side of the barbell
