This is a quote from the Tamil film 'Karakattakaran'. The question is entirely subjective and culture-dependent, requiring knowledge of Tamil cinema dialogue. Without access to the film or transcript, it's impossible to verify the correct answer objectively. Such questions are inappropriate for general competitive exams.

This appears to be another Tamil song lyric identification question from the film 'Eeram.' The line 'Edhu edhu ennai kadathi povathu..Edhu Edhu ennai puluthil saipathu' is presented as a recognizable song line. Without audio or film context, this requires knowledge of Tamil film music.

A sextant is a navigational instrument used to measure the angle between two visible objects, primarily for celestial navigation to determine latitude and longitude at sea. It can also be used for land surveying. Anemometer measures wind speed, spherometer measures curvature of surfaces, and sphygmophone is related to pulse measurement.

A colorimeter is an instrument that measures the intensity of colour by analyzing the absorbance or transmittance of light through a solution. It's used in chemistry and physics to determine concentration of colored solutions. Commutator is part of an electric motor, crescograph measures plant growth, and chronometer measures time.

A fathometer is an echo-sounding instrument used to measure the depth of water, particularly in oceans. It works by sending sound waves to the seabed and measuring the time for echo to return. Anemometer measures wind speed, manometer measures pressure, and sphygmophone is for pulse sounds.

A vernier scale is a secondary scale used on measuring instruments to provide increased precision in reading measurements. It allows measurement of small subdivisions that would be difficult to read on the main scale alone. Thermostat controls temperature, viscometer measures viscosity, and anemometer measures wind speed.

An oscillograph is an instrument that records oscillations or waveforms, particularly electrical or mechanical vibrations. It provides a visual record of how these vibrations change over time. Dynamometer measures force, drinker's apparatus is for respiration, and crescograph measures plant growth.

A crescograph is a device invented by Jagadish Chandra Bose to measure and record plant growth movements. It can detect extremely small movements and growth responses to stimuli. Chronometer measures time, salinometer measures salt concentration, and odometer measures distance traveled.

A phonograph is an instrument for reproducing sound, invented by Thomas Edison. It records and reproduces sound using a vibrating needle etching grooves on a rotating cylinder or disc. Plantimeter measures area, hygrometer measures humidity, and radar detects objects using radio waves.

EEG (Electroencephalograph) is the instrument used to diagnose brain disorders by recording electrical activity of the brain through electrodes placed on the scalp. GM counter detects radiation, ECG records heart activity, and tachometer measures rotation speed.

A teleprinter is a machine that automatically records and prints messages received over telephone wires. It's essentially a telegraph machine that prints received transmissions. Thermometer measures temperature, tachometer measures speed, and telemeter measures distance remotely.

An anemometer is a device specifically used for measuring wind speed and intensity. A barometer measures atmospheric pressure, an audiometer measures hearing acuity, and a binocular is an optical instrument for magnified viewing.

The lyric 'oru pani malai oru yeri malai viral korthu ondrai sirikum' is from the Tamil film song 'Yaradi Nee Mohini' (2008), starring Dhanush and Nayanthara. Music was composed by Yuvan Shankar Raja.
