__Dry and Liquid Measurements__
Explanation:
Density is defined as a material per unit volume of the material.
The determination of the density of a liquid with an aerometer is based on the principle of Archimedes' law: "Any object that is immersed in a liquid will experience a lift which is equal to the weight of the liquid being moved".
The aerometer is in the form of a hollow cylinder, so that the aerometer can be immersed in the right position (the scale is immersed in liquid), then the aerometer is filled with Pb grains. The scale on the aerometer shows the density of the liquid, the smaller the density of the liquid, the deeper the aerometer will be. Therefore the aerometer scale shows an increasing number from top to bottom.
Its the coformation theory, stating that the earth and moon were both made around the same time from a small dust particle
Answer:
security/protection
Explanation:
The main purpose of a data encryption algorithm is security/protection. These algorithms grab data and change it into indecipherable code. This code can only be decrypted using a key that has been uniquely created for that exact piece of data. Usually, when the encrypted data and key have been created the key is given to the select few that need to have access to the data. This process helps protect the data from being seen or manipulated by unwanted parties.
When a person or group works freely it is called 'community service'.
