Q: What term describes waves that travel through matter? Read this paragraph and choose the correct option from the provided answers: Waves that travel through mattersuch as the fabric of a flagare called mechanical waves. The matter they travel through is called the medium. When the energy of a wave passes through the medium, particles of the medium move. The more energy the wave has, the farther the particles of the medium move. The distance the particles move is measured by the wave's amplitude. Choices: - replaced waves - water waves - heat waves - mechanical waves A:
**Answer**
mechanical waves

Read this paragraph and choose the correct option from the provided answers: In addition to these properties, other physical properties of matter include the state of matter. States of matter include liquid, solid, and gaseous states. For example at 20C, coal exists as a solid and water exists as a liquid. Additional examples of physical properties include:. Choices: - Chemical - Physical - Quatitative - states A:
**Answer**

Q: How close a measurement is to the correct value for that measurement is known as what? Read this paragraph and choose the correct option from the provided answers: Accuracy and Precision of a Measurement Science is based on observation and experimentthat is, on measurements. Accuracy is how close a measurement is to the correct value for that measurement. For example, let us say that you are measuring the length of standard computer paper. The packaging in which you purchased the paper states that it is 11.0 inches long. You measure the length of the paper three times and obtain the following measurements: 11.1 in. , 11.2 in. , and 10.9 in. These measurements are quite accurate because they are very close to the correct value of 11.0 inches. In contrast, if you had obtained a measurement of 12 inches, your measurement would not be very accurate. The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions). Consider the example of the paper measurements. The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the. Choices: - frequency - rate - temperature - accuracy A:
**Answer**
accuracy

Q: What always has the same elements in the same ratio? Read this paragraph and choose the correct option from the provided answers: A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds. Choices: - component - cell - mitochondria - compound A:
**Answer**
compound
