Electric current	Altimeter
Resistance	Ohm

code :

A	B	C	D
2	3	1	4
2	3	4	1
1	3	4	2
3	2	4	1

Correct Answer: (a)

Solution:An Altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.

Ammeter is used to measure electric current in a circuit.

A seismograph is used to measure earthquake.

Ohm is the unit of electric resistance.

45. Match the correct: [Chhattisgarh P.C.S.(PRE) 2003]

List-1	List-2
Fathometer	Atmospheric pressure
Barometer	Atmospheric humidity
Hygrometer	Height
Altimeter	Depth of sea

code :

A	B	C	D
2	3	1	4
4	1	2	3
4	2	3	1
3	1	2	4

Correct Answer: (b)

Solution:Fathometer is an instrument used to measure the depth of the sea or water or a submerged objects by means of ultrasonic waves.

The barometer ,hygrometer and altimeter are used to measure the atmospheric pressure ,atmospheric moisture and height of an object respectively.

46. Fathometer is used to measure : [M.P.P.C.S.(PRE) 2015]

(a) Earthquake
(b) Rain
(c) Sound intensity
(d) Depth of sea

Correct Answer: (c) Sound intensity

Solution:

A fathometer is an echo-sounding device used to determine the depth of a body of water by measuring the time taken for a sound pulse to travel from a transducer to the bottom and return.

47. Match the list-1 with list-2 and select the correct answer from the codes given below the lists : [U.P.P.C.S.(mains) 2012, Uttarakhand Lower sub.(pre) 2010]

List-1	List-2

code :

A	B	C	D
1	2	3	4
4	1	2	3
4	1	3	2
3	1	2	4

Correct Answer: (d)

Solution:

Anemometer : wind velocity
Seismograph : earthquake
Barograph : atmospheric pressure
Hygrometer : humidity

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]

(a) The power of brightness of light
(b) Extremely high temperature
(c) Frequency of electromagnetic waves
(d) Atmosphere humidity
(e) None of above .

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.

50. The apparatus used to detect the lie is known as - [U.P. Lower sub. (pre) 2013]

(a) Polygraph
(b) Pyrometer
(c) Gyroscope
(d) Kymograph

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.
