How does a pulley make work easier?
1) it doesn't. Work = force x distance. So a pulley that reduces force will also increase distance -but -it can reduce the force needed to move somethingthus making life easier.Answer:It depends on the number of pulleys and their arrangement. A single pulley does not change the force required to lift something. But, other pulley arrangements do. Four pulleys can be arranged into a thing called a block & tackle that can divide the force required to lift something by four. But, the rope must be extended four times as long to do this.
What is equal to the ideal mechanical advantage of a pulley system?
The ideal mechanical advantage of a pulley system is two times the number of pulleys in the system. This is the amount of force required to get the system moving.
What is Dividing an object in motion is its velocity by the time necessary to make that change?
(change in speed) divided by (time required to make the change)This number is the magnitude of average acceleration.
What pulleys are in a sailboat?
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a cable or belt along its circumference. A sailboat have a number of different pulley systems to do different things like lift loads, apply forces. In sailboat pulleys are also assembled as part of belt and chain drives in order to transmit power from one rotating shaft to another. For more information visit at: yachtauthority.com
Does a change in entropy occur in purely mechanical motion?
Yes, changed in entropy refer to changed in mechanical motion. Entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder.
Change 11 into a whole number?
11 is a whole number. No change is required.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
What cannot change about an atom?
The number of protons can not be changed.
Is 31.6 irrational?
No because 31.6 is a rational number that can be changed into a fraction if required.
Why did jack tatum change his number?
Jack Tatum changed his number with the Oakland Raiders to 32. He changed it because it was his old number in college.

What is the relationship between the amount of effort and distance needed to lift a load when using different types of pulleys?
Yes, it does, but it is only a second order effect. In other words, it is so small an effect that you can almost always neglect it. What is significant is the number of pulleys in use. After a certain number of pulleys there is no advantage to adding more.
What subatomic particles could be changed without changing which element the atom is?
The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.
