Final answer:
To measure mass, use a digital scale or a double-pan balance for small objects. A digital scale gives precise measurements in units like grams, while a balance compares unknown mass with known weights. For volume measurements of small amounts, a graduated cylinder or pipette is used.
Step-by-step explanation:
To measure the mass of an object, you can use either a scale or a balance. For small objects, such as an apple or a golf ball, a digital scale or a double-pan balance would be appropriate. Digital scales offer a more precise and accurate measurement and can measure mass in various units such as milligrams, centigrams, grams, and small numbers of kilograms. A double-pan balance, on the other hand, involves comparing the unknown mass of an object with known mass standards, such as metal cylinders, until the scale is balanced. If you were to measure an object's weight, such as with a bathroom scale, the mechanics would be slightly different, as weight is a force measured in newtons (or pounds) and tied to gravity. Bathroom scales typically depress under weight, and the measurement is then converted to mass units like kilograms, taking gravity into account. However, remember that a scale's mass reading could vary between Earth and the Moon due to the difference in gravity.
As for a violin's weight, the most suitable tool would be a digital scale or a double-pan balance, depending on the desired precision. However, when it comes to measuring the volume of a small amount of a substance, such as oregano, a graduated cylinder or a pipette would be ideal. These tools are designed to measure the volume of liquids or granular substances accurately.
