What is materiality and give an example?

A classic example of the materiality concept is a company expensing a $20 wastebasket in the year it is acquired instead of depreciating it over its useful life of 10 years. The matching principle directs you to record the wastebasket as an asset and then report depreciation expense of $2 a year for 10 years.

What’s the difference between hard and soft wood?

In general, hardwood comes from deciduous tree’s which lose their leaves annually. Softwood comes from conifer, which usually remains evergreen. The trees from which hardwood is obtained tend to be slower growing, meaning the wood is usually denser.

What are the examples of soft materials?

Examples: Iron, glass. Those materials which can be easily compressed, cut, bent or scratched are called soft materials. Examples: Sponge, Cotton.

What is soft and hard magnetic materials?

Soft magnetic materials are those materials which have a smaller area enclosed by their Hysteresis loop. Hard magnetic materials are those materials which have a Larger area enclosed by their Hysteresis loop. 2. They have low remnant magnetization. They have high remnant magnetization.

What are lustrous materials?

Lustrous materials are basically those materials which have a shiny surface. Metals are known to be lustrous materials. For example iron, copper, aluminium and gold are metals, and so are lustrous.

What objects are translucent?

Translucent objects allow some light to travel through them. Materials like frosted glass and some plastics are called translucent. When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials.

What objects are rough?

Here’s a visual list of things that are rough:Alligator.Sandpaper.Nail File.Asphalt.Granite.Limestone.Coconut.Coral.More items…•

What is a soft wood tree?

Softwood is wood from gymnosperm trees such as conifers, as well as Amborella. The term is opposed to hardwood, which is the wood from angiosperm trees.

What are hard and soft magnetic materials give one example of each?

The best examples of soft magnet are iron-silicon alloys, nickel-iron alloy and iron. Hard magnetic materials: These Magnetic materials retain their magnetism in absence of magnetic field and also known as permanent magnets. Alloys composed of iron, cobalt and aluminium are generally acted as hard magnetic materials.

Whats is a material?

noun. the substance or substances of which a thing is made or composed: Stone is a durable material. anything that serves as crude or raw matter to be used or developed: Wood pulp is the raw material from which paper is made. … materials, the articles or apparatus needed to make or do something: writing materials.

What are soft hard materials?

Those materials which cannot be easily compressed, cut, bent or scratched are called hard materials. Examples: Iron, glass. Those materials which can be easily compressed, cut, bent or scratched are called soft materials.

Is wood a soft material?

Softwood is wood also known as conifers. Softwood is the source of about 80% of the world’s production of timber. … Not all softwoods are soft, but here we describe the most common species. Softwoods can be treated in wet or dry form (below 15% moisture).

What are soft magnetic materials used for?

Soft-magnetic materials are mainly used in magnetic cores of transformers, motors, inductors, and generators. Of prime importance for applications in cores are a high permeability, low magnetic losses, and a low coercivity.

Is iron a soft or hard magnetic material?

Substances that can be permanently magnetised are described as magnetically hard. These are often alloys of iron, nickel and cobalt. Substances that can only be temporarily magnetised are described as magnetically soft. Alloys with less iron, nickel or cobalt will be magnetically soft and have a weaker magnetic field.

What are the 3 types of wood?

These three types are: softwoods, hardwoods, and engineered wood. Each of these different wood types can be used in a number of different ways.

What are soft materials?

Soft materials are materials that can be easily deformed by thermal stresses or thermal fluctuations at about room temperature. Soft materials include liquids, polymers, foams, gels, colloids, granular materials, as well as most soft biological materials.

What are hard materials give example?

Those materials which cannot be easily compressed cut ,moulded or scratched are called hard materials. For example: Iron ,steel ,wood, stone ,brick, glass ,bone ,teeth, diamond.
