What fibers are stronger than steel when stretched?
Carbon nanotubes and certain types of aramid fibers, such as Kevlar, are known to be stronger than steel when stretched. Carbon nanotubes exhibit exceptional tensile strength due to their unique molecular structure, while Kevlar fibers are engineered for high strength-to-weight ratios, making them ideal for protective gear. These materials are used in various applications, including aerospace, military, and automotive industries, due to their remarkable strength and lightweight properties.
Why are gases the worst conductors of all?
Gases are poor conductors of heat and electricity because their particles are widely spaced and have weak intermolecular forces. This means that heat and electrons cannot be transferred efficiently between gas particles, resulting in low conductivity. Liquids and solids, with their closer particles and stronger intermolecular forces, are better conductors than gases.
Ion-dipole attractions are stronger than dipole-dipole attractions because?
Because ions are a whole 1+ or 2-, whereas dipoles are "a little bit (-) or a little bir (+)." So the stronger the charge, the stronger the attraction for the opposite charge.And that an Ion has a much bigger electrical charge there fore it attracts with more strenght than a dipole.
What is stronger 9 amp or 12 amps?
A 12 amp current is stronger than a 9 amp current because amperage is a measure of electrical current flow. More amps indicate a higher flow of electricity, which means a 12 amp current can power larger devices or provide more energy than a 9 amp current.
What materials would you use to make electrical wires?
Depends on the purpose. Silver is the best conductor, but it's also quite expensive. It's used when the wire must be very thin and cost is no object. Copper is the second best and much less expensive. It's the most common metal used for general purpose wiring. Aluminium isn't as good as copper, but it's cheaper and stronger. It's used in high-voltage long-distance transmission lines, where using thicker wires (which improves conduction) makes sense.
How are nanotubes stronger than steel?
It depends on the structure.
What are carbon nanotubes and their applications?
Carbon nanotubes are cylindrical shaped tubes made up of long carbon chains of the thickness of 1 billion of a meter. Their length can expand to as much as several centimetes. The physical properties of carbon nanotube such as about 60 times stronger than steel makes them ideal material in the various field. applications still under research but have wide applications in electrical components ,robotics, mechanical engg etc.
What do you mean by electrical double wrapped cross joint?
An electrical double wrapped cross joint is just like an ordinary cross joint but double wrapped with electrical tape. It is used where two tap conductors need to extend away from the branch conductor in the opposite direction and is stronger than the ordinary cross joint.
What are the potential applications of Russian nanotubes in the field of advanced materials science?
Russian nanotubes have potential applications in advanced materials science, such as in the development of stronger and lighter materials for use in aerospace, electronics, and medical devices. They can also be used in energy storage, water purification, and drug delivery systems.
Is the electrical or gravitational force stronger?
The electrical force is typically stronger than the gravitational force. On atomic scales, the electrical force dominates interactions between charged particles whereas the gravitational force becomes more significant on larger scales such as celestial bodies. In particle physics, the electrical force is found to be significantly stronger than gravity.
Is an electric eel stronger than a snake?
electrical eel is not stronger then a snake since the snake is a posinious so no
What are the differences between the action of chemical and electrical protective mechanisms of the body?
chemicals weaker and electrical is stronger bei :D
What is stronger inside an atom electric forces or gravitational forces?
Electrical forces.

Why is no torque developed by those conductors occupying positions in the interpolar spaces of a motor?
In a motor, conductors positioned in the interpolar spaces do not develop torque because they are situated where the magnetic field is relatively weak and uniform. Since torque is generated by the interaction between the magnetic field and the current-carrying conductors, a lack of significant magnetic flux means that these conductors experience little to no force. Consequently, they do not contribute to the overall torque output of the motor, which relies on conductors located in areas with stronger, varying magnetic fields.
The smaller the distance between the objects the stronger?
... the gravitational force between them, and the electrical force if the objects are charged.
Why do you use copper wires in electric wires?
Copper is an excellent conductor, ductile (can be drawn easily), and reasonably economical. For bare conductors, copper oxidises and the oxide coating prevents further corrosion. While it is heavier than aluminum, it is stronger. The alternative, aluminium, is cheaper than copper, but not as good a conductor. Aluminium is lighter, but weaker, and aluminium transmission lines require a steel-core for strength. Aluminium conductors suffer from 'cold flow', which means that aluminium conductors secured with screw terminals tend to work loose over time. Copper doesn't do this, so copper is preferred for residential/commercial electrical wiring systems.
