  1. 2. _____________ number is a term used in colloidal chemistry. It is defined as the minimum amount of protective colloid in milligrams which prevents a color change from red to violet of 10ml gold sol by the addition of 1 ml of 10%NaCl solution.
  2. 3. A capacitance of 2 µF is required in an electrical circuit across a potential difference of 1.0 kV. A large number of 1 µF capacitors are available which can withstand a potential difference of not more than 300 V. The minimum number of capacitors required to achieve this is
  3. 7. An electric dipole has a fixed dipole moment p → , which makes angle θ with respect to x-axis. When subjected to an electric field → ∧ E E 1= i , it experiences a torque → ∧ T1= τ k . When subjected to another electric field → ∧ E 3 E 2 1 = j it experiences a torque → → T T 2 1 =− . The angle θ is
  4. 8. ∆U is equal to ______ work
  5. 11. oxidation of food takes place in _____.
  6. 13. is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.
  7. 15. the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibres.

  1. 1. Two reactions R1 and R2 have identical pre-exponential factors. Activation energy of R1 exceeds that of R2 by 10 kJ mol−1 . If k1 and k2 are rate constants for reactions R1 and R2 respectively at 300 K, then ln(k2 /k1 ) is equal to : (R=8.314 J mol−1K−1 )
  2. 4. In a common emitter amplifier circuit using an n-p-n transistor, the phase difference between the input and the output voltages will be
  3. 5. A time dependent force F=6t acts on a particle of mass 1 kg. If the particle starts from rest, the work done by the force during the first 1 sec. will be
  4. 6. the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
  5. 9. m/(s^4)
  6. 10. division of a cell nucleus during mitosis
