  3. Sketch pen
  4. Roller pen

Answer and Explanation

Answer: (2) Ballpoint pen

Blobbing of a ballpoint pen is called to be the “blotchy residue” that sticks to the edge of the ballpoint pen tips. This accumulation is due to the thinning of the ball inks result from the friction of pen against paper. And when the person writes with that type of pen, a solid-thick ink globule forms which usually on the initial stokes of the writings. These blobbing of inks also seen in the hands of the writer.

26. Foot prints on wooden floor may be collected by:

  4. All of the above

Answer and Explanation

Answer: (1) Electrostatic method

Electrostatic method of lifting print uses a charged plastic film which is neatly placed over the dust print and due to electrostatic adhesions it attracts the dust particles which finally get adhered to the thin charged sheet.
Please Note: Dust prints are preserved using Photography, Tracing, and Electrostatic method.

28. The refractive index of glass is determined by

  1. Becke line method
  2. Free floatation method
  3. Pulfritchrefractometer
  4. Density gradient tube method

Answer and Explanation

Answer: (1) Becke line method

The Becke line method is used to determine the relative refractive index of glass materials. And if the Becke line appears inside the edge of a glass fragment, this means the glass piece has a greater RI than the surrounding liquid.

-> Barbiturates and Opiates
-> Newborns
-> Drowning
-> Electrocution
-> Heatstroke
-> Cholera
-> Postanesthesia
-> Cerebral concussion or insanity

39. Assertion (A): The colour of lividity in carbon-mono oxide poisoning is cherry red.
