Does weight affect a pulley?
Yes, weight has a huge effect on a pulley system. The amount of weight being moved or lifted directly affects how well the pulley works, and too much weight can break it altogether. Weight is also the main leverage in a pulley system.
What pulley can lift weight with the least amount of force?
Pulley X
How much effort is exerted if the weight is 400 grams and the pulley used is a movable pulley?
The answer will depend on the distance that the 400 grams has to be moved.
What are the three kinds of pulley?
1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load
How much effort is needed to lift a 75 N weight using the pulley system?
If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.
How are the double pulley systems different?
Double pulley systems are different from the one pulley system because the weight is now attacked to a pulley instead of an anchor. Another pulley is used to take some of the weight. A two pulley system only requires half the effort as a single pulley system.

How much effort force would you use to lift a kg weight with a fixed pulley system?
a lot
How much effort force would you use to lift a 300-kg weight with a moveable pulley system?
150
How much effort force would you use to lift 300 kg weight with a fixed pulley system?
a lot

Pulley X
What is the relationship between the effort and the weight of an object being lifted over a simple pulley?
the effort needed to lift an object is about the same as the weight of an object:)
How much effort is exerted if the weight is 400 grams and the pulley used is a movable pulley?
The answer will depend on the distance that the 400 grams has to be moved.
How much effort force would it take to lift a 300 kg weight with a movable pulley system?
It would take 150 kg to lift the load.

What are the uses of double pulley in physics?
The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up
