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 Option (2) i.e Pancreas.

Key Points

• In humans, the kidney is one of the main organs of the excretory system.
• The kidney's function is the filtration of the blood and removing waste(toxic) products.
• Waste products and excess fluid are removed through the urine.
• If the kidney fails person needs to undergo dialysis.
• Dialysis is a treatment that filters and purifies the blood using a machine
• The human excretory system includes certain organs that eliminate the wastes such as salts, carbon dioxide, urea, uric acid and water produced by the body.
• The path of the urine in the human excretory system is -
• After filtering from the kidney → The urine through Ureter → Stored in the Urinary bladder → Exits through the urethra.

Important Points

• The Pancreas is an organ located in the abdomen. It is not a part of the human excretory system.
• The Pancreas plays an important role in converting the food we eat into fuel for the body's cell.
• It helps in the process of digestion. It also regulates blood sugar.
• The body system that removes metabolic wastes from the body is known as the 'Excretory System'.
