Answer:
756 feet pound
Step-by-step explanation:
Length of the chain, L = 18 feet
weight of chain, W = 84 pound
If we lift the centre of gravity of the chain, it will entirely lift up. The centre of gravity of the uniform chain is at its mid point. So, the work done
W = weight x half of length
W = 84 x 9
W = 756 feet pound
5mph
Step-by-step explantion:
0.5 times 20 equals 10
10/2 equals 5
x^2/3
(x^5/6)/(x^1/6)=x^(5/6-1/6)=x^4/6
simplify 4/6, you get 2/3.
2. YWX
<T and <Y are congruent
<W and <W are congruent
<Z and <X are congruent
