Materials and Their Applications Questions

Multiple choice physics some natural phenomena types of charges and their interaction transfer of charges charging and discharging transfer of charge

What is the frictional order of the following materials on rubbing:

ebonite, glass rod, wool, plastic

  1. Wool, glass rod, ebonite, plastic

  2. Glass rod, wool, plastic, ebonite

  3. Wool, glass rod, plastic, ebonite

  4. Glass rod, wool, ebonite, plastic

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

When any of these materials are rubbed together, the one in higher order gets positive charge (+) and the one in the lower order gets negative charge (-). The correct frictional order is: glass, wool, ebonite and plastic.

Multiple choice physics sources of energy biomass and biogas biogas conventional sources of energy

Biogas plant is generally made of what?

  1. Bricks

  2. Wood

  3. Tiles

  4. Plaster of Paris

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

Temperature inside the biogas increases tremendously during the anaerobic fermentation process. Out of the given options, brick is the suitable material to be used for the making of the biogas plants to withstand high temperatures.

Multiple choice chemistry substances in the surroundings - their states and properties elastic behaviour of solids elastic and plastic substances properties of substances

Which one of the following substance possesses the highest elasticity?

  1. rubber

  2. glass

  3. steel

  4. copper

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

Modulus of elasticity gives the idea of elasticity. For above materials, values of E are:
Glass: $50-90 GPa$
Rubber:$ 0.01-0.1 GPa$
Steel:$ 200 GPa$
Copper: $117 GPa$

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.
