WebApr 24, 2024 · Within the global buildings segment, energy intensity will decline as new, energy-efficient technologies are adopted. As a result, the energy needs per capita at a global level will be 10 percent less in 2050 than they were in 2016, despite the rapid rise in demand from the many households entering the middle class in emerging economies. WebAnswer: The amplitude of a sound wave is the measure of its maximum displacement from its equilibrium position. Energy is related to amplitude because the greater the amplitude of a sound wave, the more energy it carries. Intensity of sound is defined as the amount of sound energy that passes through a unit area in a unit of time.
