To match the instrument with the appropriate decimal place, let's consider the options provided:
Option 1: A barometer measures atmospheric pressure to the nearest tenth of a millimeter of mercury.
In this option, the barometer measures atmospheric pressure. The instrument records the pressure to the nearest tenth of a millimeter of mercury. Therefore, the appropriate decimal place for this instrument is the tenth place.
Option 2: A thermometer measures temperature to the nearest hundredth of a degree Celsius.
In this option, the thermometer measures temperature. The instrument records the temperature to the nearest hundredth of a degree Celsius. Therefore, the appropriate decimal place for this instrument is the hundredth place.
Option 3: A stopwatch measures time to the nearest hundredth of a second.
In this option, the stopwatch measures time. The instrument records time to the nearest hundredth of a second. Therefore, the appropriate decimal place for this instrument is the hundredth place.
Option 4: A voltmeter measures voltage to the nearest hundredth of a volt.
In this option, the voltmeter measures voltage. The instrument records the voltage to the nearest hundredth of a volt. Therefore, the appropriate decimal place for this instrument is the hundredth place.
To summarize:
- Barometer measures atmospheric pressure to the tenth place.
- Thermometer measures temperature to the hundredth place.
- Stopwatch measures time to the hundredth place.
- Voltmeter measures voltage to the hundredth place.
