Statics

Yes, friction can involve static friction when two surfaces are not moving relative to each other, and kinetic friction when the surfaces are in motion. Both types of friction occur due to the interaction between the surfaces at a microscopic level.

A static charge can be dissipated by grounding it through a conductive material like metals or by using devices such as grounding straps or ionizers. This allows the excess electrons to flow away, neutralizing the charge and preventing static electricity buildup.

A static load on a roof could be the weight of the roof itself, as well as any permanently fixed structures such as solar panels, HVAC units, or satellite dishes. These loads do not change or move once installed and exert a constant force on the roof structure.

Well I think iM not sure that high altitude discharge its when the charged solar particles acumulate and the lighting occurs and the gorgeuus celestial phenomenon resulting from this effect its the aurora

Fabrics like nylon and polyester tend to generate more electricity when rubbed or pressed together due to their triboelectric properties. Fabrics with a mix of synthetic and natural fibers can also produce significant amounts of static electricity when rubbed against each other.

Not according to Newtons Law:

Forces = Mass X Acceleration

However, in a vacuum, after you used your force on an object and it now has motion, the object will have motion for eternity, even when there is no force. So as a matter of fact, it is possible. Just not on any planet, only in outer space.

Dust particles are attracted to newly polished cars because the smooth surface of the polish reduces friction, allowing particles to stick more easily. Additionally, the static charge on the polished surface may also attract dust particles.

That's actually only possible in a First Class lever. In that case, moving the

fulcrum closer to the load makes it easier to lift the load, since it now takes

less force at the effort end. But the effort force also has to move through a

greater distance than it did before, in order to lift the load to the same height.

To find the reaction force of a cantilever, you can sum the moments about the fixed end of the cantilever (often where it's attached to a wall or support). The reaction force will balance the external load applied to the cantilever to maintain equilibrium. Equation of equilibrium can be used to solve for the reaction force.

Anti-static wrist bands or anklets help ground a person and divert static electricity. This is useful when a person works in demolition. A spark can ignite plastic explosives, and the anti-static wrist bands greatly reduce the likelihood that static electricity would detonate the materials prematurely.

Probably not to you or other people. But it can damage sensitive electronic

things. And if it doesn't kill them right away, it can shorten the life of some

electronic components, so that the device dies sooner than it would have.

A free-body diagram of a football being kicked would include forces such as gravity pulling the ball downward, the force exerted by the kicker's foot pushing the ball forward, and air resistance opposing the ball's motion. The diagram would show these forces acting on the football as vectors.

A. A rubber bend of length .7m is stretched to connect to points A and B. A tension force of 40 N is thereby developed in the band. A 20-N weight is then attached to the band at C. Find the distance a that point C moves downward if the 20-N weight is constrained to move vertically downward along a frictionless rod.

[Hint If you consider part of the band, the "spring constant" for it will be greater than that of the whole band]

To add static to microfiber cloths, you can rub the cloths against a balloon or use a fabric softener sheet in the dryer when you launder them. This will help the microfiber cloths attract and hold onto dust and dirt more effectively.

An example of static load is a book resting on a table. The weight of the book creates a force that is evenly distributed and does not change over time.

Static load refers to a stationary force acting on a structure or a component. It is a constant force that does not change over time. Static load is important to consider in engineering and construction to ensure that structures can safely support the weight placed on them without failure.

To find the amount of mechanical energy lost when colliding with a floor, you can calculate the difference in kinetic energy before and after the collision. Subtract the final kinetic energy (which would be zero if the object comes to a stop) from the initial kinetic energy to determine the mechanical energy lost during the collision.

The answer is that it is NOT.

It is a first class lever.

"Class 1: the fulcrum is located between the applied force and the load. Example: the crowbar" - Wikipedia

In regular use, the fulcrum of the oar is attached to the top side or edge of the water craft, which is between the force being applied by the rower and the "load", being the resistance of the water itself.

This makes the oar a classic example of a first class lever.

During refueling, the airplane and the fuel truck are connected to metal hooks

in the ground, to avoid static electrical sparks, and nobody is allowed to smoke

anywhere near the fueling operation. In that way, there's nothing around to

ignite the fuel, or any fumes that might escape into the air.

Both static and current electricity involve the movement of electrons. In static electricity, electrons build up on an object's surface, creating an imbalance of charge. In current electricity, electrons flow through a conductor, creating an electric current.

Static friction is stronger than sliding friction because when two surfaces are at rest relative to each other, the irregularities in their surfaces can bond together more strongly, requiring more force to initiate movement. On the other hand, once the surfaces start sliding past each other, the contact points are in motion and can move more freely, resulting in lower frictional resistance.

Not always easy. Since density is defined as the mass of a unit volume of material,you would measure the volume of the rock by putting it into a container half filled with water and then measure the volume change.

A static frequency converter works by converting input AC power at one frequency into output AC power at a different frequency without the need for mechanical components. This is achieved by using power electronics components like transistors and capacitors to adjust the frequency of the electrical signal. Static frequency converters are commonly used in applications where different frequencies are required, such as aircraft and ship power systems.
