Foghorns are another method of warning ships that they are close to the shore. Foghorns emit low-pitched sound waves in all directions that can be heard on ships when visibility is low. Low-pitched waves have longer wavelengths that are less likely to be blocked by barriers such as rocks. Compare the warning signals emitted by a lighthouse with those emitted by a foghorn. Select all the correct answers. You may select more than one answer for each scenario.

Based on Figure 1, which data is the student trying to produce by conducting the investigation?

Based on the experiment in the passage, select the statement that accurately describes the increase or decrease of the kinetic energy of the particles.

Students take turns pitching a softball and a baseball to determine whose pitch has the most kinetic energy. Each student pitches a ball, and the teacher measures the speed using a digital radar detector. Analyze the data in Table 1 and Table 2 from the passage. Using the patterns in the data, which list ranks the pitches from least kinetic energy (first) to most kinetic energy (last)?

Which new question are the students investigating in Figure 2?

A student is attempting to move a piece of furniture from Point A to Point Band argues that another student in the room should help push the furniture.The other student argues that only one person is needed, and they shoulduse coasters under the edges of the furniture. Which statement supports theargument that only one student is needed to push the couch shown inFigure 1?

Investigating which question would best help the student explain theobservations about the tape?
