35. Intake of which one of the following food components should be minimised by patients having Gouty Arthritis due to elevated serum uric acid level?

Correct Answer: (b) Nucleic acids
Solution:Gout is caused by the accumulation of uric acid crystals in joints. Uric acid is the metabolic end-product of purines, which are found in high concentrations in nucleic acids (DNA and RNA). Patients with gout are advised to avoid purine-rich foods (like organ meats and certain seafood) to lower serum uric acid levels.

36. Which one of the following statements about microbes is not correct?

Correct Answer: (c) No antibiotic has been obtained from any microbe.

38. An object moves in a circular path with a constant speed Which one of the following statements is correct?

Correct Answer: (a) The centripetal acceleration of the object is smaller for a gentle curve (i.e., curve of larger radius) than that for a sharp curve (i.e., curve of smaller radius).
Solution:In centripetal acceleration. If the speed (v) is constant, the acceleration is inversely proportional to the radius (r). Therefore, a larger radius (gentle curve) results in smaller acceleration, and a smaller radius (sharp curve) results in larger acceleration.

39. The force acting on a particle of mass m moving along the x-axis is given by F(x) = Ax² - Bx. Which one of the following is the potential energy of the particle?

Correct Answer: (b) −(x² / 6)(2Ax − 3B)
Solution:

40. The symbol of SI unit of inductance is H. It stands for:

Correct Answer: (c) Henry
