Electrocardiography is the process of producing an electrocardiogram a graph of voltage versus time - of the electrical activity of the heart using electrodes placed on the skin.

Answer from: liliaboop9325

The electrocardiogram records the electrical signals of heart.

Explanation:

It is a type graph that records the electrical signals or rate of the heart. It is also called ECGs.

It is a common test that is used to detect the problems in heart and also monitor the status of the heart in many conditions.

During the ECG, sensors (electrodes) that can detect the electrical activity of the heart are attached to the chest.

Hence, the type of data recorded by the electrocardiogram is the electrical signals of heart.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
