Question Discussion & Solution

Curator means in charge of a museum similarly Warder is in charge of Prison.

i) Shyam travels 5 km towards East and turns left and moves 6 km further.

ii) He then turns right and moves 9 km.

iii) Finally, he turns once again to his right and moves 6 km.

Drawing the Diagram as per the given information:

AB = 5 km

DE = BC = 9 km

Distance between the starting point and the final point = AB + BC = 5 + 9 = 14 km

Hence, the correct answer is "14 km".

The correct answer is Sulphur Cycle

Key Points

• The sulphur reservoir is in the soil and sediments where it is locked in organic (coal, oil and peat) and inorganic deposits (pyrite rock and sulphur rock) in the form of sulphates, sulphides and organic sulphur.
• It is released by weathering of rocks, erosional runoff and decomposition of organic matter and is carried to terrestrial and aquatic ecosystems in a salt solution.
• The sulphur cycle is mostly sedimentary except two of its compounds, hydrogen sulphide (H2S) and sulphur dioxide (SO2), which add a gaseous component.
• Sulphur enters the atmosphere from several sources like volcanic eruptions, combustion of fossil fuels (coal, diesel etc.), from the surface of the ocean and gases released by decomposition.
• Atmospheric sulphur dioxide is carried back to the earth after being dissolved in rainwater as weak sulphuric acid (acid rain).
• Sulphur bound in a living organism is carried back to the soil, to the bottom of ponds and lakes and seas through excretion and decomposition of dead organic material.

Concept:

Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. 

Explanation:

In C++ we have two types of polymorphism:
1. Compile-time Polymorphism – This is also known as static (or early) binding.
2. Runtime Polymorphism – This is also known as dynamic (or late) binding.

Compile-time Polymorphism
Function overloading and Operator overloading are examples of Compile time polymorphism.

The correct answer is Banded Column.

• Banded Column is used in Ms-Word to make the formatting of even columns different from subject columns.

Key Points

• Banded Column 
  • ​Adding colour to alternate columns.
  • Banded columns are available in the Design tab.
  • Excel’s Conditional Formatting feature allows us to apply cell shading to every other row in a worksheet.
• • By selecting the range we want to apply banded columns, and then click Conditional Formatting > New Rule under Home tab.
  • For applying banded columns, we can use this formula =MOD(COLUMN(),2)=0.

​Additional Information

• Banding
  • Adding colour to alternate rows or columns called banding.
  • It can make the data in our worksheet easier to scan. 
• Banded rows
  • The term banded rows are referring to the shading of alternating rows in a worksheet.
  • Excel’s Conditional Formatting feature allows us to apply cell shading to every other row in a worksheet.
