句子主干为“heat and sound are forms of energy”,空格后为定语从句“can be converted/changed from each other”。分析选项:1. **选项A(as)**:引导定语从句时通常用于“such...as”结构或非限制性定语从句,此处无“such”呼应,且从句缺主语,as无法在此单独作主语,排除。2. **选项B(such as)**:用于...
太阳能风光互补系统 Yes, solar energy can be converted into power. This process is commonly known as solar power generation. Solar panels, which are made up of photovoltaic cells, capture sunlight and convert it directly into electricity through the photovoltaic effect. This electricity can then be...
The device has an energy storage device whose stored energy can be converted into useable heat. The energy storage device can be a latent heat storage device, a fuel cell, a chemical energy storage device or an electrochemical energy storage device. The shoe sole can convert mechanical energy ...
Energy can be transferred from one form to another. For example, electrical energy can be converted into light energy. The word “into” in this sentence is a/an ___. A. prep B. conj C. verb D. adjective 相关知识点: 试题来源: 解析 A。“into”是介词,表示“到……里”,在这里表...
Mathematically, it can be expressed as: Efficiency(η)=Useful Work OutputHeat Energy Input×100% 2. Defining 100% Efficiency: If a heat engine were to have 100% efficiency, it would mean that all the heat energy input is converted into useful work output. This implies: Useful Work Output=...
Solar energy can be **converted** into power. This means that solar energy, which is the radiant light and heat from the sun, can be transformed into a usable form of energy, such as electricity, to power homes and businesses. **1. Analyze the meaning of the sentence:** The sentence...
One feature of this new law is quite easy to understand is this: In Einstein relativity theory, anything which has energy has mass -- mass in the sense that it is attracted gravitationaly. Even light, which has energy, has a "mass". When a light beam, which has energy in it...
Tens of thousands of small-scale hydro energy storage sites could be built from Australia's farm dams, supporting the uptake of reliable, low-carbon power systems in rural communities, new UNSW-Sydney-led research suggests.
