Frictional resistance is the force that opposes the movement of an object over a surface, resulting from the interaction between the surface and the object. It is caused by the microscopic irregularities on both surfaces that come into contact and create resistance to motion.

Is and example of inherent resistance?

One example of inherent resistance is antibiotic resistance in bacteria. Some bacteria naturally possess genes that allow them to survive exposure to certain antibiotics, reducing the effectiveness of those drugs in treating infections. This inherent resistance can make it challenging to treat bacterial infections and necessitates the development of new antibiotics.


How can you define strenght?

Strength can be defined as the physical or mental ability to exert force against resistance. It can also refer to a person's capacity to withstand pressure, challenges, or hardships.


What is the measure of resistance to the flow of fluid?

When fluids-- liquids or gases-- move through pipes or ducts, they meet resistance. Resistance occurs because outer layers of the fluid are "held back" by a friction-like force as the layers slide by the walls of the pipe or duct. Resistance occurs also between fluid layers within the fluid as they slide past one another. Whatever the cause, fluid resistance in a pipe or duct affects both (1) flow rate and (2) pressure drop along the pipe.


What is viscocity Define viscosity briefly?

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid, with higher viscosity fluids being thicker and flowing more slowly than lower viscosity fluids. Water has a lower viscosity compared to honey, for example.


Is class 1 fire rating the same as 1 hour fire resistance?

In short, No - in the UK "Class 1" is a form of performance that indicates how easily something burns ('Class 4" being the worst). Fire resistance on the other hand is a term that relates to a construction's ability to resist the passage of fire (e.g. a wall, floor, door etc). The fact that a material is "Class 1" doesn't necessarily have any bearing on its fire resistance performance. For example, PVC cladding can be obtained to a 'Class 1' rating, but it wouldn't contribute much to the wall's fire resistance performance at all.

What is meant by the resistance of an electrical component?

Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.

Define Internal Resistance?

The internal resistance of a device is the resistance in ohms of that device. It is the resistance electrons need to overcome before electricity is said to flow.


When tempratere increase resistance increase and when resistance increase current decrease why?

That's what "resistance" is all about: reducing the current for a given voltage. In fact, you can DEFINE resistance as voltage divided by current.


Define the term critical field resistance?

critical resistance is the maximum resistance beyond which the generator failed to exite. it can b found form the occ of the generator.


How does paul hewitt define intertie?

Inertia is the resistance of any physical object. This is taught in science.


Define electrical conductivity?

Conductivity is the inverse of resistance. Since Ohm's Law states that current is voltage divided by resistance, it also states that current is voltages times conductivity.


How can you define the flow of fluids?

it is so simple to define the flow of fluid . because in fluid there is no intermolecular forces and also it depends on viscosity. some liquid possess more resistance to flow like honey.. n some possess low resistance like water, honey etc

There isn't a CD player that offers the best shock resistance since they all pretty much offer this feature and the charcteristic which define this feature is universal for most players.


Define centroid and moment of inertia?

Can you define the words tubing exercises?

Tubing exercises are exercises that require resistance from a stretchy band. The band is stretched and works the muscles harder than without the band because of the resistance. There is some great instruction of tubing exercises on youtube.
