Physics Measuring Instruments

Correct Answer: Barometer

A clock is a device used to measure, keep, and indicate time. An alarm is a feature or a specific type of clock, but clock is the broader term for the instrument.

A vibrometer is an instrument used to measure vibration, specifically displacement, velocity, or acceleration.

A balance scale works by comparing the mass of an object against known standard weights. Other tools like rulers measure length, and graduated cylinders measure volume.

A Celsius thermometer is specifically designed to measure temperature. A stopwatch measures time, a pan balance measures mass, and a meter stick measures length.

An anemometer is the standard instrument used in meteorology to measure wind speed. A barometer measures atmospheric pressure, and an altimeter measures altitude.

The Scoville scale measures the concentration of capsaicin, which determines the pungency or heat of chili peppers.

An anemometer is an instrument used to measure the speed of the wind.

For hygiene and safety, all probes used in electrolysis must be sterile and disposable to prevent cross-contamination between clients.

Melde's experiment demonstrates the relationship between frequency, tension, mass per unit length, and wavelength (via loop length) in a vibrating string.

1.The oscillator circuits consists of a negative gain op-amp and a three section $RC$ network that produced the $180^{o}$phase shift.The phase shift network is connected from op-amp output back to its inverting input.

Hectare and metre are used to measure distances while gram is used to measure mass, and water is measured in terms of volume which is measured as litre.

Sensors are hardware devices that detect physical properties like heat, light, or pressure and convert them into signals the computer can process.

A galvanometer is an instrument used for detecting and measuring small electric currents. The other options are either incorrect terms or unrelated devices.
