Question Discussion & Solution

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 Displacement.

Key Points

•  Displacement
  • When a body moves from one position to another, the shortest distance between the initial position and final position of the body along with direction is known as Displacement.
  • Its SI unit is a meter.
  • It is a vector quantity.
  • Displacement of the object can be positive, negative, zero.
  • Displacement of the object can never be greater than the distance traveled by it.
• When there is no change in an initial position and final position even after covering some path, then it is considered zero displacements.

Additional Information

• Distance
  • It is the actual path covered by a moving body irrespective of the direction in which the body travels.
  • Its SI unit is a meter.
  • It is a scalar quantity.
  • An odometer is used to measure the distance traveled by the vehicle.  
• Speed
  • The time rate of change of position of the object in any direction is called the speed of the object.
  • It is a scalar quantity.
  • Its SI unit is m/s.
  • Speed= Distance travelled/Time taken
• Frequency
  • It tells us how frequently an event occurs.
  • The number of complete waves produced in one second is called the frequency of the waves.
  • Hertz is the SI unit of Frequency. It is named in the honor of Rudolf Hertz.
  • 1 Hertz= 1 vibration per second.

The pattern followed is:

Hence, the correct answer is "72".

Ammeter is an instrument used to measure Current.

Similarly, Hygrometer is an instrument used to measure Humidity

The correct answer is All of the above.
