Which material is least elastic?
Answer. Rubber has the lest elasticity. This question can be answered based on the property Elastic Limit. Elastic Limit is the most extreme burden a given material would withstand with no perpetual twisting.
What means elastic?
Adjective. elastic, resilient, springy, flexible, supple mean able to endure strain without being permanently injured. elastic implies the property of resisting deformation by stretching. an elastic waistband resilient implies the ability to recover shape quickly when the deforming force or pressure is removed.
Is demand elastic or inelastic?
Elastic demand means there is a substantial change in quantity demanded when another economic factor changes (typically the price of the good or service), whereas inelastic demand means that there is only a slight (or no change) in quantity demanded of the good or service when another economic factor is changed.
Are fresh tomatoes elastic or inelastic?
The supply of fresh tomatoes is relatively inelastic; a fall in price does not significantly change the quantity on offer.
Is soft drink elastic or inelastic?
The price-elasticity of soft drinks is −1.37 implying that a 10% increase in price would be followed by a decrease of 13.7% in the amount consumed, which shows an elastic demand.
Is food elastic or inelastic?
A food is said to be price inelastic—not responsive to price—when its own-price elasticity is greater than -1.0. A food is said to be price elastic—responsive to price—when its own-price elasticity is less than -1.0.
What is the difference between elastic and flexible?
Explanation: Elasticity means the object will regain its original form as soon as the deforming force is removed. Flexibility means the object is just easily deformed, and will stay that way.
Which is more elastic Mcq?
Air is more elastic than water.
Why is a material not perfectly elastic?
This is because for a material to be perfectly plastic it should be able to get elongated infinitely but no material can be stretched infinitely. If we stretch any material then it is sure that it will break at some moment, so no material is perfectly plastic.
Does elastic mean flexible?
Elastic is the rubber-based material that resumes its original shape after stretching or compression, and anything described as elastic is flexible.
What are examples of elastic goods?
5 Examples of Elastic Goods
- Soft Drinks. Soft drinks aren’t a necessity, so a big increase in price would cause people to stop buying them or look for other brands.
- Cereal. Like soft drinks, cereal isn’t a necessity and there are plenty of different choices.
- Clothing.
- Electronics.
- Cars.
Why is rubber so elastic?
Natural rubber is made of long chains of molecules called polymers. Because these polymers are so long (they can be thousands of molecules long) they get tangled up in themselves. The result is a property called elasticity, the polymers are elastic. This is why rubber bands are sometimes called elastic bands.
Are fresh carrots elastic or inelastic?
Among the fresh vegetables sold by ounce, onions have the most inelastic elasticity while carrots have the most elastic elasticity. Among the fresh vegetables sold by count, lettuce has the most inelastic elasticity while celery has the most elastic elasticity.
Is air more elastic than water?
Water is more elastic than the air because we know that the bulk modulus of elasticity is reciprocal of compressibility. So the answer is water is more elastic than air because it is less compressible than the air.
Is a sports car elastic or inelastic?
Understanding Inelastic Necessities and medical treatments tend to be relatively inelastic because they are needed for survival, whereas luxury goods, such as cruises and sports cars, tend to be relatively elastic.
Is rubber elastic or plastic?
Rubber is an example of elastic materials. Any metallic materials will be an example for plastic materials.
Which is more elastic rubber or steel?
If the same amount of force is applied to a steel wire and to a wire made of rubber of same length and cross-sectional area, the extension of rubber wire is easier than the extension of the steel wire. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.
What is elastic limit?
Elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
Is Coca Cola elastic or inelastic?
For example, according to Ayers and Collinge, the demand for soda (Coca-Cola or Mountain Dew) is very elastic. This means that a small variation in price could produce a large change in the demand, which comes from the competition that exists in the soda market.
Which is more elastic water or air or solid or Crystal?
Answer. Water is more elastic than air because bulk modulus of elasticity is reciprocal of compressibility and air is more compressible than water.
Which is the most elastic?
rubber
What products are elastic?
Examples of price elastic demand
- Heinz soup. These days there are many alternatives to Heinz soup.
- Shell petrol. We say that petrol is overall inelastic.
- Tesco bread. Tesco bread will be highly price elastic because there are many better alternatives.
- Daily Express.
- Kit Kat chocolate bar.
- Porsche sports car.
Why are vegetables elastic in demand?
This is because vegetables fall under necessities and with necessities, demand rises with income, but less than proportionately. Vegetables have an income elasticity of demand of between 0 and +1.
Which is more elastic water or solid?
Water is more elastic than air because bulk modulus of elasticity is reciprocal of compressibility and air is more compressible than water.
Is Merlot elastic or inelastic?
Taken together, the price elasticity of red wine is closer to an equilibrium, neither inelastic nor elastic, unless you only want red wine. Lastly, Merlot is the most elastic of our goods. Those who buy Merlot want it because of its particular characteristics – it’s smooth, round, and easy to drink.
Is rubber a plastic?
Both these compounds are polymer materials. They have unique properties depending on their chemical structures. The main difference between plastic and rubber is that plastic is essentially a synthetic polymer whereas rubber can be found as a natural polymer or can be produced as a synthetic polymer.
