From the graph of stress and strain of two solid materials. According to Hooke's law the material having large plastic region will be  Correct Answer Ductile

Correct option-1

Concept:

According to Hooke’s law,

“For small deformation, the stress in a body is proportional to the corresponding strain.”

i.e. stress  ∝ strain 

or stress = (E) (strain)

Here, E is a constant called the modulus of elasticity.

Now, depending upon the nature of the deforming force applied on the body, stress, strain,

and hence modulus of elasticity are classified into the following three types:

1. Young's modulus

2. Bulk modulus and

3. Modulus of rigidity

Explanation:

  • If a material having a large plastic region will be considered ductile.
  • It means the material can be easily drawn into thin wire.
  • This ductility property is also associated with the young's modulus of elasticity.
  • The larger the value of young's modulus greater will be the ductility.


Hence, option - 1 is correct

Focusing on plastic pollution, the June issue of the National Geographic magazine created quite a buzz on social media, contrary to expectations after the cover featured a plastic bag submerged in an ocean with a ’Planet or Plastic?’ text on it. Ironically, the magazine itself was wrapped in a double layer of plastic. Which of the following options can be the reason for the magazine to go viral on the internet as inferred from the statements? I. It highlighted the amount of single-use plastic that enters in the world’s oceans which is a major environmental concern these days. II. National Geographic kicked off its ‘Planet or Plastic’ campaign, the magazine’s multiyear effort to raise awareness about the global plastic trash crisis through the cover. III. The magazine about ocean plastic pollution came wrapped in a plastic bag inside another plastic bag. IV. Because they realized the major flaw and announced that the magazine will no longer be shipped to readers in a plastic bag but will be sent out in a paper envelope instead.

Given below are four-sentence paragraphs (S1 -S4). S1 and S4 are given. From the options (P, Q, R) choose two sentences which can be S2 and S3. S1: Today, you can hardly look around you and not spot some item that is made entirely from plastic or has some plastic ingredient.  S2: S3: S4: Because of this many governments strictly control its use and create complex law that govern its creation, recycling P. This is not perfect as plastic has several disadvantages that prevent it from becoming universal building block of modern human civilization. Q. This only proves that plastic has managed to become popular building material of millions of useful items. R.  This troublesome ability of plastic doesn’t have great immediate impact on our environment.
In the following question, the first and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R, S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. S1. Plastic bags are a major cause of environmental pollution. P. Many countries around the globe have either ban the plastic bag or Levi tax on it. Q. Plastic as a substance is non-biodegradable and thus plastic bags remain in the environment for hundreds of years polluting it immensely. R. However, the problem hasn’t been solved completely because the implementation of these measures hasn’t been as successful. S. It has become very essential to ban plastic bags before they ruin our planet completely. S6. Research shows that waste plastic bags have been a major reason for untimely animal deaths.
