Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.
This depends on their intended use.
Pulleys have been in use for thousands of years, with evidence suggesting that they were invented around 1500 BC in ancient Mesopotamia. Their design and use were further refined by the Greeks around 400 BC. This means that pulleys have been utilized for approximately 3,500 years.
yes car engines are pulleys
A system of pulleys is called a block and tackle
idk but pulleys were made in Sicily 250 B.C
Many people use pulleys in their jobs. The rides like Supreme scream, which go vertically up and down have pulleys in them. Elevators have pulleys in them, and people who ship cargo use pulleys in their cranes.
at the rock climbing place they use pulleys to keep you safe :D
No, zip lines are not an example of movable pulleys. Zip lines use a combination of gravity and mechanical devices to transport riders from one point to another, but they do not incorporate pulleys in the same way that other systems, such as flagpoles or blinds, do.
tape, flagpoles, those things you use for rock climbing, and the pulleys the construction people use! :)
a combination of one or more fixed pulleys and one or more movable pulleys such as a crane

No
assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object
An exercise machine can incorporate pulleys as part of its design, but it is not inherently a pulley itself. Pulleys are simple machines that change the direction of force, while exercise machines often use a combination of pulleys, weights, and resistance mechanisms to facilitate workouts. Therefore, while some exercise machines utilize pulleys, they are more complex systems designed for various types of exercise.

To pulled things up
This depends on their intended use.
