Question Discussion & Solution

The correct answer is In 1956.

• In 1956 the "Immoral Traffic (Prevention) Act" was enacted.

Key Points

• Immoral Traffic (Prevention) Act
  • This Act may be called the Immoral Traffic (Prevention) Act, 1956.
  • It extends to the whole of India.

Additional Information

• Immoral Traffic (Prevention) Act
  • ​In pursuance of the International Convention signed by India in 1950 pertaining to the Prevention of Immoral Trafficking, a comprehensive Act called Immoral Traffic (Prevention) Act was enacted in 1956.
  • It makes the sexual exploitation of male and female a cognizable offence.

The correct answer is option 3 i.e. the Atomic Number

• The periodic table is based on Atomic Number.
• The atomic number is the number of protons found in the nucleus of every atom of that element. 
• The periodic table is managed by the International Union of Pure and Applied Chemistry, or IUPAC.
• In 1869, Dimitri Mendeleev included 63 known elements arranged according to increasing atomic weight. But there were many elements he could not place in the periodic table and with the discovery of new noble elements, there was a need to arrange the elements. Henry Moseley later arranged the elements in the periodic table by their number of protons rather than their atomic weights.
• The modern periodic table orders the elements according to increasing atomic number rather than increasing atomic weight.
• There are 118 elements in a periodic table. There are seven periods and eighteen groups in the modern periodic table.
• On moving from left to right in a period, the size of atoms(atomic size) decreases.
• On moving from left to right in a period, the metallic character of elements decreases, whereas the non-metallic character increases.
• While going down in a group of the periodic table, the size of atoms increases (or atomic size increases).
• While going down in a group of the periodic table, the metallic character of elements increases.
• Electronegativity and reactivity of non-metals increase along the period and decrease down the group.

Concept:-

 Single linked list:

This list consists of a number of nodes in which each node has a next pointer to the following element. The link of the last node in the list is NULL, which indicates the end of the list.

Calculation:-

After perform ((Start → Next) → Next) the current link transfer to the third node of linked. And Third node data value is 128.

Hence the correct answer is 128.

The correct answer is 240 J.

Key Points

• When a force is applied to an object which causes displacement along the direction of force then the work is said to be done by that force.
• The work done by a force is defined as "the product of the component of the applied force on the block in the direction of the displacement and the magnitude of this displacement" is called work done.

Additional Information

• i.e., \(W = \vec F.d\vec x = Fdx\cos \theta \)

or in terms of magnitude, it can be given as

\(W\; = \;F \times s\)

• Here both force and displacement will be along the same direction since force is causing this displacement thus Work done is a scalar quantity.
  • Here,
  • Force applied on object = F
  • Displacement of object = dx
  • Distance traveled by an object = s
  • The angle between Force and displacement = θ
• Calculation:
  • Given that,
  • Person raised the box of weight 120 N through the height of 2 m
  • i.e., F = 120 N 
  • x = 2 m
• Thus from the above explanation, we can see that
• Work = Force × Distance moved in the direction of the force
• Force of 120 N is acting downwards, Therefore
  • Work Done = 120 × 2 = 240 J

The correct answer is one party to another party to marriage or parents of one party to another party to the marriage.

Key Points

Dowry System:

• Dowry, or the custom of accepting gifts by the bridegroom’s parents from to bride’s parents as part of a marriage settlement.
• Dowry is the money, valuables, goods, estate or property which the bride party gives to the groom's party in exchange for marriage.
• The Dowry system is most prevalent in village areas where people are uneducated and a girl is considered as a burden on their family.
• With upcoming times, this practice is not that common in urban areas.
• To prevent the system of dowry, The Dowry Prohibition Act, 1961 was enacted.
• Section 2 of the Prohibition of Dowry Act defines dowry as any property or valuable security given or agreed to be given either directly or indirectly.
• Dowry is given by one party to a marriage to the other party to the marriage or by the parents of either party to a marriage or by any other person, to either party to the marriage or to any other person.
