What else can I help you with?
Do sound waves carry work?
No, sound waves do not carry work. Work is done when a force acts on an object to move it over a distance. Sound waves propagate through a medium by transferring energy through oscillations of particles, but they do not perform mechanical work on objects they encounter.
How can levers move objects?
Levers can move objects by using a pivot point, called the fulcrum, to apply a force. When force is applied to one end of the lever, it creates a turning effect that can lift or move objects on the other end. Levers are simple machines that allow us to exert a smaller force over a greater distance to move larger objects.
What happens to the waves from a vibrarting source as their distance from the source increase?
As the waves move away from the vibrating source, their amplitude decreases. This is due to the spreading of the wave energy over a larger area as the distance increases. The waves also experience dispersion and attenuation, resulting in changes in their shape and intensity.
How can an inclined plane help to move objects?
An inclined plane reduces the amount of force needed to move objects by allowing the force to be spread out over a longer distance. This makes it easier to lift or lower objects along the slope of the inclined plane compared to moving them vertically.
Does the wheel and axle increase or decrease your force?
The wheel and axle increases your force by allowing you to apply a smaller force over a longer distance to move a larger load over a shorter distance. It amplifies the force applied to the wheel, making it easier to lift or move heavy objects.

Is i true inclined plane increase the distance over wicth a force is applied?
Yes, an inclined plane increases the distance over which a force is applied in exchange for reducing the amount of force required to move an object vertically. This allows for easier movement of objects by spreading the force over a longer distance.
What happens to objects with same density as air around it?
IT keeps moving until takes place over mentionlessly, neither it floats or sinks. unless the waves in the water or something move it
How are parallax and a parsec linked?
Parallax is the apparent relative motion of objects when an observer moves. That is, when your head (or your telescope) move back and forth you see different objects move different amounts. More distant objects move less than closer objects. You can use this to calculate the distance of an object. Specifically, if an object appears to move by one arc-second (1/3600 of a degree) over 6 months (i.e. as the Earth has moved 2 AU), then it is 1 parsec away - a bit over 3 light-years.
What forms as a result of the wind's frictional force on water?
Waves form as a result of the wind's frictional force on water. The wind transfers its energy to the water, causing it to move and generate waves. The size and shape of the waves depend on the strength of the wind and the distance it travels over the water.
Which of these uses sound waves to measure the distance between objects underwater?
Sound waves bounce off the ocean floor and come back up to whatever emitted it. The time it takes for the sound wave to come back tells how far down it went. Doing this many times over and over, one can map out the ocean floor, and if the sound wave comes back relatively fast, that means there is something on the ocean floor.
What is a flat slanted surface to make it easier to move an object over distance?
A ramp is a flat slanted surface that helps move objects over distances by reducing the effort needed to lift them. Ramps are commonly used for wheelchair accessibility, loading and unloading heavy items, and in construction to move materials.
What is an example of fetch in waves?
An example of fetch in waves is the distance over which the wind blows uninterrupted to create waves. The longer the fetch, the larger and more powerful the waves can become.
