The force advantage of the direction changing pulley shown is 1. The correct option is b.
<h3>What is force advantage?</h3>
Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.
In the single fixed pulley, there is only one rope segment that pulls up on the load, so,
The force advantage is
F.A = 50 N / 50 N = 1
Thus, the force advantage of the direction changing pulley shown is 1. The correct option is b.

Answer:
option B
Explanation:
given,
two plane are moving in same altitude at a distance of 1.0 km apart.
angle of depression of the two planes given are 45° and 37°
now, the diagram is attached below
using diagram,
now in ΔAOC
tan 45° =
x = h..................(1)
now using triangle ΔBOD
tan 37° =
from equation (1)
0.754 =
0.754 h + 753.56 = h
0.246 h = 753.56
h = 3063.5 m
hence, the correct answer is option B
