You are at a concert sitting 160 meters away from the speakers on the stage. the sound takes 2 seconds to reach your ear from the speaker. Which of the following is true: 1. The frequency is 20 Hz

2. The wavelength is 160 meters

3. The wave is 80 m/s

4. The amplitude is 2

3 is correct because 160/2 gives 80.

Explanation:

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
