Question Discussion & Solution

Logic:

Train, Bus, and Boat are all vehicles,

Whereas a wheel is not a vehicle but a part of it.

Hence, "Wheel" is the odd word.

The correct answer is Aravali Ranges.

• The oldest fold mountain ranges in the world is Aravali Ranges.

Key Points

• Aravalis are one of the world’s oldest fold mountains running in north-east to south-east direction from Delhi to Palampur in Gujarat. 
• It is an example of the relict mountain.
• Guru Shikhar is the highest peak of Aravali.
• The Aravalli Range dates back to times when the Indian Plate was separated from the Eurasian Plate by an ocean. 
• Three major rivers and their tributaries flow from the Aravalli, namely Banas, Sahibi and Luni.

Additional Information

• The Western Ghats are locally known by different names such as Sahyadri in Maharashtra, Nilgiri hills in Karnataka and Tamil Nadu and Annamalai hills, Cardamom hills in Kerala.
• The Himalayas are young fold mountains of the tertiary period, which were folded over the Tethys Sea due to inter-continental collision.
• They stretch from the Indus River in the West to the Brahmaputra River in the East.
• The Alps are the highest and most extensive mountain range system that lies entirely in Europe, and stretch approximately 1,200 km.

The correct answer is the formula bar.

Key Points

• By using the Defined names, the user can make the formulas much easier to understand and maintain.
• The user can define a name for a cell range, function, constant, or table. With the practice of using names in the workbook, the user can easily update, audit, and manage these names.
• The user Defined names will appear in the formula bar. 

Additional Information

• Steps to define names from a selected range
  • Select the range you want to name, including the row or column labels.
  • Select Formulas > Create from Selection.
  • In the Create Names from Selection dialog box, designate the location that contains the labels by selecting the Top row, Left column, Bottom row, or Right column check box.
  • Select OK.
• Steps to use names in formulas
  • Select a cell and enter a formula.
  • Place the cursor where you want to use the name in that formula.
  • Type the first letter of the name, and select the name from the list that appears.
  • Or, select Formulas > Use in Formula and select the name you want to use.
  • Press Enter.
• How to manage names in your workbook with Name Manager
  • On the Ribbon, go to Formulas > Defined Names > Name Manager. You can then create, edit, delete and find all the names used in the workbook. 

The correct answer is Violence.

Key Points

• Violence
  • It is defined by the World Health Organization in the WRVH as “the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation” 

Additional Information

• Nonviolence
  • It is the personal practice of not causing harm to one's self and others under every condition.
• Hatred
  • It is an angry or resentful emotional response to certain people or ideas. 

CONCEPT:

• It is the property of liquid by virtue of which the free surface of the liquid at rest acting like a stretched membrane trying to contract to reduce its surface area.
• Surface tension is a force per unit length (or surface energy per unit area) acting in the plane of interface between the liquid and the bounding surface.
• It is the extra energy that the molecules at the interface have as compared to the interior.
• The surface tension is the force acting perpendicular on a unit length of an imaginary line drawn on the surface of the liquid and it can be expressed as

\(\Rightarrow T = \frac{F}{l}\)

• Because of this surface tension, few insects can easily float on liquid surface similarly a needle can be made to float on the surface of liquid using this principle

Here,

T = surface tension,

F = force acting on the surface (Cohesive force)

l = unit length

EXPLANATION:

• As explained above, the surface tension acting on a fluid surface can be expressed as

Surface tension, \(T = \frac{{{\rm{The\;cohesive\;force\;between\;molecule}}}}{{unit\;length}}\) 

• Also, we know that cohesive force or the attractive force between the liquid molecules is inversely proportional to its temperature.
• Since as we increase the temperature of fluid its interatomic distance will keep on increasing hence it will cause a decrease in the surface tension of the fluid.

i.e., \(surface\;tension,\;T \propto \frac{1}{{temperature}}\)

So, only option 3^rd is correct.
