Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Modern materials science has led to the substitution of traditional metals like steel and copper with plastics, ceramics, and high-strength glass fibers in various industrial applications due to their specific properties.

Multiple choice evs walls tell stories construction of fort and museum architecture as power: forts and sacred places forts and temples in medieval period

Which material was used to construct the Qutub Minar?

  1. Granite

  2. Basalt

  3. Red sandstone

  4. Yellow sandstone
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Red Sandstone was used to construct Qutub Minar. It was widely used in constructing forts due to it's various qualities like it's durability, strength, resistance to abrasion, easy handling, availability and so on.

Multiple choice physics option c: imaging optical instruments : telescope the reflecting telescope optical telescope xx radio telescope and space telescopes
Which material should be chosen to make the concave mirrors of a high resolution telescope so that it can also withstand temperature variations?

  1. Quartz

  2. Flint glass

  3. Crown glass

  4. Combination of Flint and Silica
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Quartz makes an ideal mirror. Its high hardness results in the smoothest micropolished surface possible, and its thermal dimensional stability allows the optician to produce a flat surface with almost no edge defects.

Multiple choice conduction in metals and non-metals thermal energy transfers physics

a container that suits the occurrence of an isothermal process should be made of 

  1. Copper

  2. Glass

  3. Wood

  4. Cloth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An isothermal process requires the system to maintain a constant temperature. A good thermal conductor like copper allows heat to flow easily between the system and the surroundings to maintain that temperature.

Multiple choice physics heat and temperature anomalous expansion of water thermal expansion in solids, liquids and gases thermal expansion

Crucibles are made of mixture of quartz and silica since the linear coefficient of expansion is

  1. Zero for that mixture

  2. Infinity for that mixture

  3. Negative for that mixture

  4. Positive for that mixture
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Its thermal expansion is practically zero. Bricks of this type are used in the melter crown of the glass furnace as they provide good resistance to creep and good mechanical strength at the operating temperature.

Multiple choice chemistry substances in daily use polyester and acrylic rayon and nylon synthetic fibres

Why PET is increasingly used for making bottles, jars and utensils?

  1. It is light weight and very strong

  2. It is shatter proof

  3. Impact resistant

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

PET is light weight, naturally colourless with high transparency, strong and impact resistant. It is shatter proof. All these properties of PET makes a highly more suitable material than glass for making bottles, jars, utensils etc.

Multiple choice elastic energy properties of material substances elasticity properties of matter physics

A material capable of absorbing large amount of energy before fracture is known as 

  1. Ductility

  2. Toughness

  3. Resilience

  4. Plasticity
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Toughness is the ability of a material to absorb energy and plastically deform without fracturing. 

It is defined as the amount of energy per unit volume that a material can absorb before rupturing.

The correct option is option(b)

Multiple choice social studies print culture and the modern world film and print media evolution of writing and communication system great reformers and reform movements

Cai Lun beat plant fibres, cloth, rope and the bark of trees, soaked these in water, and then pressed, drained and dried the pulp to create _______.

  1. Shirt

  2. Carpet

  3. Paper

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cai Lun is regarded as the inventor of paper and the papermaking process in 105 AD. He created a sheet of paper using mulberry and other bast fibres along with fishnets, old rags, and hemp waste and then pressed, drained and dried the pulp to create paper. He took paper beyond being a technical invention and helped drive its widespread adoption such that it became a successful innovation.

Multiple choice physics light and shadow substances which allow light to pass through and those which do not transparent, opaque and translucent objects shadows

Which of the following is a transparent?

  1. Gold

  2. Glass

  3. Stone

  4. Plastic
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Objects which allow the light to pass through them completely without any obstruction are called $ \bf{transparent} $ objects.

Objects which allow the light to pass through them partially are called $ \bf{translucent} $ objects.

Objects which do not allow the light to pass through them are called $\bf{opaque} $ objects.

Glass is a $\bf{transparent} $ object because it allows light to pass through it completely and doesn't block any light. 
Gold and Stone, on the other hand, are $ \bf{opaque} $ objects. While, Plastic is $ \bf{translucent} $.

Hence, the correct answer is OPTION B. 

Multiple choice chemistry materials we use soap and detergents soap soap and detergent

Glycerol is added to soap. It functions :

  1. as a filler

  2. to increase lathering

  3. to prevent rapid drying

  4. to make soap granules
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cleansing action of Soaps and detergents-
  • Most of the dirt is oily in nature and oil does not dissolve in water. The molecule of soap constitutes sodium or potassium salts of long chain carboxylic acids. In the case of soaps, the carbon chain dissolves in oil and the ionic end dissolves in water.
  • Glycerol is a humectant - a substance that attracts water.
  • It has the ability to draw in moisture preventing drying of the skin.
  • Hence, Glycerol is added to soap to prevent rapid drying.
