What results when two waves that are completely out of phase meet?
A: constructive interference that results in a greater amplitude
B: destructive interference that results in a greater frequency
C :destructive interference that results in a lower amplitude
Answer:
The result is a superposition which is twice the amplitude of each input wave. Φ = π means the two waves are completely OUT OF PHASE, and so add completely destructively. The result is a superposition which has no amplitude at all.

Which items are biomass energy sources? Select all correct answers.
the sun
wood chips
manure
paper
Answer:
wood chips, paper, and manure are biomass energy sources.
Explanation:
Biomass energy is energy generated or produced by living or once-living organisms.
Wood chips, paper, and manure are biomass energy sources. The primary form of energy from renewable sources that can be utilised to replace fossil fuels on a long-term basis is biomass.
Energy created or generated by living or formerly living creatures is known as biomass energy. Plants like the aforementioned maize and soy are the most prevalent types of biomass that are utilised for energy. These creatures' energy may be used to generate electricity or be burnt to provide heat. Direct combustion is the primary method of producing most of the power from biomass. In a boiler, biomass is burnt to create high-pressure steam. These turbine blades revolve as a result of the steam flowing over them. Wood chips, paper, and manure are biomass energy sources.
