48. Which one of the following is not correctly matched ? [U.P.P.C.S.(PRE) 1999, U.P.P.S.C.(GIC)2010]

a) Manometer - Pressure
b) Carburetor - internal combustion engine
c) Cardiography - heart movement
d) Seismometer - curvature of the surface

Correct Answer: (d)
Solution:
  • Manometer is measured Pressure. A manometer is used to measure pressure differences.
  • Carburetor - internal combustion engine. A carburetor is a device that mixes air and fuel in an internal combustion engine.
  • Cardiography  is measured heart movement. Cardiography is the process of recording the electrical activity of the heart over time using electrodes placed on the skin.
  • Seismometer is used to detect and measure earthquakes and other ground vibrations, not the curvature of the surface.

49. Phonometer is used to measure which one of the following ? [U.P.P.C.S.(MAINS) 2014]

Correct Answer: (e) None of above .
Solution:Phonometer is an instrument which is used for testing the force of human voice in speaking. Photometer is used for measuring the intensity of light.

Correct Answer: (a) Polygraph
Solution:

A polygraph popularly referred to detect the lie measure and records several physiological indices such as blood pressure respiration and skin conductivity while the subjects is asked  the answer a series of question.

A pyrometer is a type of remote-sensing device used to measure the high temperature of a surface.

A gyroscope is a spinning wheel or disc in which the axis of rotation is free to assume any orientation.

Kymograph is an instrument for recording variations in pressure as of the blood or in tension as of a muscle by means of a pen or stylus that marks a rotating drum.
