What else can I help you with?
What helps and hinders work?
FRICTION
What A material that hinders the passage of electric charge is?
An insulator material such as rubber or plastic hinders the passage of electric charge because it does not allow electrons to flow freely. This property makes insulators useful for insulating and protecting electrical wires and components.
What both helps and hinders work?
FRICTION
How does friction move an object?
Friction doesn't cause or create movement, it's a force that prevents or hinders movement.
Why do certain materials have electric resistance?
Certain materials have electric resistance due to the collisions between the electrons and atoms within the material, which hinders the flow of electric current. The resistance is caused by factors such as the type of material, temperature, and impurities present in the material.
A material that doesnt allow electrons to move through it easily is an?
insulator. Insulators have high resistance to the flow of electric current, which hinders the movement of electrons through the material. This property makes insulators useful for applications where electrical conductivity needs to be limited.
Why the electrical conductivity of material decreases with resistivity incrreasing?
As resistivity increases, it indicates that the material has more resistance to the flow of electricity. This increased resistance causes a decrease in electrical conductivity, as the electrons have a harder time moving through the material. In essence, higher resistivity hinders the ability of electrons to freely move and carry electrical current.
How much friction should be there between the ground and the person's shoes to avoid slipping?
The friction between the ground and a person's shoes should be high enough to prevent slipping, but not so high that it hinders movement. Factors such as the type of shoe sole, the material of the ground, and the presence of any liquids or debris can all affect the level of friction needed to prevent slipping..preprocessing
Why is the drift velocity in an electrical wire so small?
The drift velocity in an electrical wire is small because the electrons in the wire move slowly due to frequent collisions with atoms in the wire's material, which hinders their overall movement.
A material that hinders the passage of electric charge is?
An insulator is a material that hinders the passage of electric charge. Insulators have high electrical resistance, which prevents the flow of electric current through them. Examples of insulating materials include rubber, glass, and plastic.
What are three occasions when friction not wanted?
Friction is not wanted in situations where it hinders motion (like in moving parts of machinery), causes wear and tear (like in brakes), or generates heat (like in bearings).
What is the friction that hinders a stationary object from moving on a surface when a force is applied to that object?
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
