Wow you people are dumb even i know and im in pre - school
A combined pulley system makes it easier to lift an object compared to a single pulley system. By distributing the load across multiple pulleys, the force required to lift the object is reduced.
A fixed pulley does not provide any mechanical advantage, meaning it does not reduce the amount of force needed to move an object. Additionally, it changes only the direction of the force applied, not the magnitude.
A disadvantage of a fixed pulley is that it does not provide any mechanical advantage, meaning it does not change the direction or magnitude of the force applied. This can make it challenging to lift heavy loads without additional force.
A combined pulley system can reduce the amount of force needed to lift a load, but it depends on the specific setup of the pulleys. In an ideal scenario, a combined pulley system could reduce the force required by half, but this is not always the case in practice due to factors such as friction and inefficiencies in the pulley system. Consulting a physics textbook or a professional engineer could provide more accurate information for a particular system.
The disadvantage of a fixed pulley is that if it's not fixed in a location where you need it, it's used less.
the disadvantage of a fixed pulley is not to push it down and up
fixed and movable pulleys can be combined.
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.

make life easy to lift
I don't actually know for sure
a few jobs are people that wash windows and painters

maybe or maybe not it may depend on what type of elevator it is but i think yes
