GK Questions: General Science(Physics) – Set 8

Hello Aspirants. Welcome to Online General Knowledge section in Affairs cloud, which is important for all the competitive exams. We have created Some questions related to General Science(Physics) !!!

1. Which is used to measures the power of an electric circuit ?
1.Ammeter
2.Anemometer
3.Wattmeter
4.Voltmeter
5.None of these
Explanation :
The wattmeter is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit. Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.

2. Theodolite measures ………………………………….
1.Horizontal angles
2.Vertical angles
3.Critical angles
4.Both 1 and 2
5.None of these
Answer – 4.Both 1 and 2
Explanation :
Theodolite is a surveying instrument with a rotating telescope for measuring horizontal and vertical angles

3. Which is used to receive and transmit a reply immediately ?
1.Transponder
2.Transducer
3.Transmitter
4.All of these
5.None of these
Explanation :
Transponder is a device for receiving a radio signal and automatically transmitting a different signal.

4. Flux meter is used to measures ……………………………
1.Altitudes
2.Magnetic flux
3.Angles
4.Refractive Indices
5.None of these
Explanation :
A Fluxmeter is an electronic integrating, digital display instrument. The Fluxmeter can be used not only for the measurement of the magnetic flux of permanent magnets, but also for quality control and sorting of magnetic products.

5. Which of the following is used to records physiological movements graphically ?
1.Ohmmeter
2.Pyrometer
3.Electroenphalograph
4.Kymograph
5.None of these
Explanation :
A kymograph (which means ‘wave writer’) is a device that gives a graphical representation of spatial position over time in which a spatial axis represents time.

6. Wave meter measures…………………….. of a radiowave
1.Refractive Indices
2.Frequency
3.Wavelength
4.Range
5.None of these
Explanation :
A wavemeter (or wavelength meter) is a kind of interferometer which is used for precise wavelength measurements on laser beams.

7. …………………………….. is used to measure inner and outer diameter of solids
1.Dynamo
2.Calipers
3.Calorimeter
5.None of these
Explanation :
A caliper  is a device used to measure the distance between two opposite sides of an object and also used to measure inner and outer diameter of solids

8. Anemometer measures ………………………….. of wind
1.Force of wind
2.Direction of wind
3.Velocity of wind
4.Both 1 and 3
5.None of these
Answer – 4.Both 1 and 3
Explanation :
An anemometer is a device used for measuring Force and direction of wind. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed measurement instrument used in meteorology .

9. Which is used to find the latitude of a place by navigators ?
1.Sextant
3.Theodolite
4.Chronometer
5.None of these
Explanation :
A sextant is a doubly reflecting navigation instrument used to measure the latitude between any two visible objects. The principle of the instrument was first implemented around 1730 by John Hadley and Thomas Godfrey but it was also found later in the unpublished writings of Isaac Newton.

10. ……………………………. of a vessel at sea is measured by Chronometer
1.Altitude
2.Longitude
3.Depth
4.Pressure
5.None of these
