Question Discussion & Solution

The correct answer is Pirated Software.

Key Points

• Pirated Software is the unauthorized use, duplication, or sale of copyrighted software.
  • Pirated software is software that has been copied or distributed for free or at a vastly reduced price against the wishes of the creator.
  • The term "piracy" comes from the music industry and specifically the illegal broadcasting of music without paying a royalty.
  • Windows 10 automatically scans your computer for pirated software.

Additional Information

• Cracked software is usually (but not always!) pirated.
• The operative term is ‘crack’, which means that some type of patch or workaround was applied to defeat copy protection.

The correct answer is caffeine.

Caffeine is the main active constituent of tea and coffee.
Additional Information

• Caffeine works by stimulating the central nervous system (CNS), heart, muscles, and the centres that control blood pressure.
  • Caffeine can raise blood pressure, but might not have this effect on people who use it all the time.
  • Caffeine can also act like a “water pill” that increases urine flow.
• Nicotine works by stimulating our nervous system to release specific chemical messengers (hormones and neurotransmitters) that affect different parts of our brain and body.
  • One hormone that nicotine affects is epinephrine, also known as adrenaline.
• Chlorophyll is a green pigment found in plants.
  • Plants use chlorophyll and light to make food.
  • People sometimes use chlorophyll as medicine.
  • Common sources of chlorophyll used for medicine include alfalfa, algae, and silkworm droppings.

The correct answer is "option 2"

CONCEPT:

Structure in C is a user-defined data type that is used to store the collection of different data types.

The total size of the structure is the sum of the size of every data member.

Union is a user-defined data type that is used to store different data types in the same memory location.

The total size of the union is the size of the largest data member.
 

EXPLANATION:

Given the size of short, float and long is 2 bytes, 4 bytes, and 8 bytes, respectively.

Therefore,

Size of Structure → size of ( short s[5] ) + size of Union  

Here, Size of Union = 8 bytes   { largest data member is long }.

Size of short s[5] → 2×5 → 10 bytes

Size of Structure → 10+8 →18 bytes.

Hence, the correct answer is "option 2".

Concept:

• Electric current is the rate of flow electric charge or free Electrons in a definite direction through any section of wire. Its SI unit is ampere(A).
• The direction of the conventional current corresponds to the direction of positive charge which is from higher potential(positive) to lower potential(negative).

I = Q / t

I is current, Q is charge, t is time

Explanation:

Q = I t

So Charge is the product of current and time.

Unit of current is Ampere, and unit of time is an hour. 

So, Amount of charge or Quantity of electricity is Ampere-hour 

According to given information,

Whatever be the distance covered by the person, when the man stops he is facing south.

Hence, the answer is ‘South’.
