• It was declared illegal between 1932-34. It led the movement to end British rule and was the government party after independence from 1947-77.

Key people-Congress Party Leader: 

•  Maulana Abul Kalam Azad (1888-1958): Leading Muslim member of Congress Party; Congress president, 1940-1946; Indian education minister after independence.
•  Mohandas Karamchand Gandhi (Mahatma) (1869-1948):  Studied law in London; 1893-1914, worked in South Africa; on return to South Africa, rose to dominance in Congress Party, becoming its president in 1924.

The Correct Answer is 24.

Key Points

• Human ribs are flat bones that form part of the rib cage to help protect internal organs.
• Humans usually have 24 ribs, in 12 pairs.
• The first seven pairs are attached directly to the sternum by costal cartilages and are called true ribs.
• The 8th, 9th, and 10th pairs are called false ribs, they do not join the sternum directly but are connected to the 7th rib by cartilage.

Additional Information 

• Human ribs are flat bones that form part of the rib cage to help protect internal organs.
• Humans usually have 24 ribs, in 12 pairs.
• Only 1 in 500 people have an extra rib known as a Cervical rib. 
• At the front of the body, most of the ribs are joined by costal cartilage to the sternum.
• Ribs connect to vertebrae at the costovertebral joints.

The correct answer is 2 ms^-2

• We know that according to Newton's 2^nd law, 
  • ​Force = Mass × Acceleration
  • or \((\vec F = m \times \vec a)\)
• Here, F = 100 N and Mass = 50 Kg
• So, 100 = 50x a ⇒ a = 100/50 = 2.
• Hence, the acceleration will be 2 ms^-2.

• Force: A force is something that changes the state of rest or motion of a body.
  • It causes the body to start moving if it is at rest or stops if it is in motion or deflects from the initial path.
  • Force is a vector quantity having SI unit Newton (N) and dimension (MLT^-2).
• According to Newton’s Second law of motion
  • The rate of change of momentum of a body is directly proportional to the resulting force acting on a body
  • Mathematically it can be expressed as 
• \(\vec F \propto \frac{{d\vec p}}{{dt}}\;or\;\vec F = m \times a\)

The correct answer is Switched Mode Power Supply.

• The full form of SMPS is Switched Mode Power Supply.

​Key Points

• SMPS or switched-mode power supply 
  • SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. 
  • The circuit consists of a rectifier, voltage regulator transformer, and a filter. 
  • The input supply is turned On and Off by MOSFETs.
• Fundamentally, different types of circuits work with various kinds of power supplies such as SMPS.
