Question Discussion & Solution

The correct answer is Seventh Schedule.

Key Points

• Seventh Schedule
  • The Seventh Schedule of the Constitution of India defines and specifies the allocation of powers and functions between States and the Union.
  • The Schedule contains three lists - Union List, State List, and Concurrent List.
  • The Union List originally had 97 subjects. Now it has 100 subjects.
  • The State List has 61 subjects now, It had 66 subjects initially. State legislatures can make laws on the subjects mentioned in this list.
  • The Concurrent List has 52 subjects enumerated under it. Both the State as well as the Central Government can make laws mentioned on this list.

Additional Information

• 9.8 m/s² is the value of acceleration due to the gravity of the surface of the Earth.
• The acceleration which is gained by an object because of the gravitational force is called acceleration due to gravity.
• Its SI unit is m/s²

All the 3 statements are correct.

• Protection of Women from Domestic Violence Act 2005 came to effect from October 26, 2006.
  • ​The Act was passed by the Parliament in August 2005.
  • Protection of Women from Domestic Violence Act 2005 is passed by the Indian Parliament in 2005.​
  • The magistrate can impose monthly payments of maintenance.
  • Apart from the victim herself, the complaint can be lodged by any person.
  • Penalty up to one year or a fine of Rs 20,000 can be imposed.

Additional Information

• The Act seeks to cover those women who are in a relationship with the abuser where both parties have lived together in a shared household.
• The  Act provides for the appointment of Protection Officers and NGOs to provide assistance to the woman.
• One of the most important features of the Act is the woman's right to secure housing.
• The Court can also issue protection orders that the abuser will not harass the women at her workplace.
• A Breach of a protection order is a non-bailable offence.

Explanation:

Trend in metallic property:

• As we move along a period from left to right, the metallic character decreases. The elements which are at the extreme left of the periodic table are most metallic in nature and the elements at the right side of the periodic table are non-metals in nature.
• As we go down the group, the metallic character increases and the non-metallic character decreases.
• So, metals at the extreme left and bottom of the periodic table are most metallic in nature.

Reactivity:

• As the metallic character increases, the Ionisation potential decreases and the reactivity of the elements also increases.
• The most reactive metal is thus Cs (Cesium), situated at the bottom left corner of the periodic table.

​

Hence, the most active metal known is Cesium.

• Francium is the element present at the bottom of the periodic table, but it is a lab-made element, and not naturally occurring, which makes Cs as the most reactive element. 

Explanation:

• Bronze is an alloy of copper and tin as the two main constituent elements.
• Bronze is a copper-based alloy that typically consists of approximately 88% copper and 12% tin.
• Some other elements added in minute quantities can be aluminium, nickel or zinc.
• It is one of the first alloys used by mankind and an entire era known as the 'Bronze Age' is known because of the extensive use of the alloy in many human artefacts.

Additional Information

Steel: 

• Stainless steel is an alloy of iron and chromium.
• Steel is an alloy of iron and carbon.
• Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon, and other alloying elements.

Solder:

• Soldering is a joining process used to join different types of metals together having different properties. 
• Solder is a metal alloy, usually made up of tin and lead which is melted using a hot iron (soldering iron).
• The iron is heated to temperatures above 600˚F which then cools to create a strong bond.
• Flux material used in soldering is ZnCl2 (Zinc Chloride) and NH4Cl (Ammonium Chloride).

Brass:

• Brass is a metal alloy that is made up of copper and zinc.
• The proportions of zinc and copper can vary to create different types of brasses with different properties.
• It has higher malleability than bronze or zinc and has a relatively low melting point (900 to 940 °C).

Mistake Points

• Copper was the first metal used by men.
• Copper was first used by man over 10,000 years ago.  
• Probably copper can be found as a naturally occurring native metal that is sometimes found in large lumps on the ground.
• People learned to make this into copper tools and other things, although, for a metal, it is quite soft.
• When it was melted over the fire, people learned how to make an alloy called bronze, which is much harder and stronger than copper.
