Question Discussion & Solution

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 Western disturbances.

Key Points

• Western Disturbances are responsible for the rainfall during winter over the northwestern part of India.
• The Western Disturbance originates in the mid-latitude region near Europe and the Atlantic Ocean.
  • The low pressure builds up over the Mediterranean Sea and moves over Iraq, Afghanistan, and Pakistan before entering India, and contains substantial amounts of moisture.
  • When these low-pressure systems reach the Indian subcontinent, they are blocked by the Himalayas and rain as snow over the northwestern plains and the higher reaches of the western Himalayas.
  • After precipitation over northwest India, they weaken and are devoid of moisture, they blow as dry winds that form dense fog over the northern plains of India.

Additional Information

• The period June to September is referred to as the Southwest Monsoon period.
  • Southwest Monsoon period is the principal rainy season for the Indian subcontinent.
  • This is the summer monsoon period where the southwest monsoon holds away over the country.
  • The whole country receives nearly 75% of its rainfall during this period.

The correct answer is Dot Matrix.

Important Points

• Impact printer
  • Impact printer refers to a class of printers that work by banging a head or needle against an ink ribbon to make a mark on the paper.
  • The three most common forms of impact printers are:
    • Dot-matrix.
    • Daisy-wheel.
    • Line printers.

Key Points

• Dot-matrix Printers 
  • The technology behind dot-matrix printing is in such a way that the paper is pressed against a drum (a rubber-coated cylinder).
  • The electromagnetically-driven printhead moves across the paper and strikes the printer ribbon situated between the paper and printhead pin.
  • The impact of the printhead against the printer ribbon imprints ink dots on the paper which create human-readable characters.

Additional Information

• Laser Printer
  • ​A laser printer is a printer that uses a focused beam of light to transfer text and images onto paper. 
• Inkjet printer
  • ​Inkjet printers, as the name implies, use ink to print text, graphics, and images onto various types of paper. 
  • Inkjet printers, cartridges, and supplies are more widely available therefore cheaper than their thermal printer.
• Thermal printer​
  • Thermal printers use tiny heating elements to activate or transfer pigments.
  • Thermal printers are used most commonly to create labels, safety signs.
