A single pulley has no mechanical advantage, it just changes direction.
In order to answer that, I'd have to see the drawing of the pulley
that's right next to the question in the book you copied it from.

The simple pulley is the type of pulley that does not have a mechanical advantage.
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
there are many advantages of pulley and they are it change the direction of force
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
