When you stand on a bathroom scale it displays the blank the earth is exerting on you?
The force.
If a person wants to raise the 100 N weight how much downward force must he exert on the rope?
If you have a single pulley, then you would need to exert 100N + an amount to overcome friction in your pulley.If you have 2 pulleys, rope connected to a beam at top, descends through pulley on item lifted, and back up through pulley at the top and then down to where you are pulling. Then the force is split in half and you would exert 50N + an amount to overcome friction.If you connect a rope to the item, up through a double pulley, down through a pulley on the item, and back up through the double pulley again and down to the person who is pulling. Then you divide the force into thirds, and the force is 33.3N + an amount to overcome friction.Essentially count the upward pulling ropes and divide by that number. A rope simply looping over a pulley that you're hanging onto the other end of only counts as once, and would be no different from you pulling up directly on the object, or on a pulley connected to the object.
Which forces come from inside the Earth and cause sudden changes to its surface?
Gravitational force Tectonic force Diastrophism
Which force changes Earth's surface most slowly?
i think volcano
How of these combines with changes in a fluid's density and the force of gravity to set convection currents in motion?
heating and cooling of a fluid
A fixed pulley changes what force?
A fixed pulley changes the direction of the force.
What is an effect on fixed pulley?
The fixed pulley only changes the direction of the force applied.
A fixed pulley changes the?
... direction of a force.
A single fixed pulley changes the direction of the?
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

What is the mechanical advantage of a single fixed pulley?
Thew pulley changes the direction of the effort force.
What is a single fixed pulley?
A single fixed pulley is a simple machine that only changes the direction of the force applied, not the amount. An example is the pulley in window blinds.
How does a fixed pulley act as machine?
It changes the direction of the input force only
How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
What kind of rope is used in a fixed pulley?
A single continuous rope that is known as block and tackle is used. A fixed pulley changes the direction of the force on a belt or rope.
