To measure the activity of a sample, a scintillation counter can be used. This instrument detects and quantifies ionizing radiation emitted by radioactive samples, converting the energy from the radiation into measurable light pulses. The number of pulses is proportional to the activity of the sample, allowing for accurate assessment of its radioactivity levels. Other instruments like Geiger-Muller counters and ionization chambers can also be utilized for similar measurements.
a microphone is the best answer to that!!
A polarimeter is used to measure the rotation of polarized light passing through a substance. It is commonly used in chemistry to determine the concentration, purity, and specific rotation of chiral compounds. It is also used in the food and pharmaceutical industries for quality control purposes.
A seismometer (replacing the outdated term seismograph), but other instruments may also respond to an earthquake. The simplest example of a seismograph is a pendulum.
A graduated cylinder or a volumetric flask would most likely have been used to find the volume of each sample. These lab instruments are designed to accurately measure liquid volumes.
It is called a hydrometer.Also, density equals mass divided by volume.See the Related Questions to the left for more information about hydrometer and density.yup

The medical term is electroencephalograph (EEG), which is a device used to measure the electrical activity of the brain.
An electroencephalogram (EEG) is the most common instrument used to measure brain activity by recording electrical patterns in the brain. EEG is non-invasive and helps in diagnosing conditions like epilepsy, sleep disorders, and brain injuries.
A colorimeter is an instrument used to measure the amount of a chemical substance based on its color. It works by passing light through a sample and measuring the absorbance or transmittance of light, which can then be correlated to the concentration of the substance.
A tool commonly used to measure minerals is a refractometer. This instrument determines the refractive index of a mineral sample, which can help identify the type of mineral based on how light is bent as it passes through the sample.
A seismometer (replacing the outdated term seismograph), but other instruments may also respond to an earthquake. The simplest example of a seismograph is a pendulum.
No. The instrument used to measure wind speed is an anemometer.
The instrument which is used to measure snowfall is called a snow gauge.
Used to measure earthquake activity with sound waves.
A mass spectrometer is the instrument used to measure the relative abundance of an isotope. It does this by separating isotopes based on their mass-to-charge ratio and providing a qualitative and quantitative analysis of the isotopic composition of a sample.
