根据第一段前两句“Sound is a form of energy that can't beseen. We can sense sound.”可知声音是一种看不见的能量形式,但能感觉到,C项错误。根据第四段第三、四“If youput a few grains of rice on the drum gently. The vibrations maycause the rice to jump.”可知轻轻地在鼓上放几粒米。
7.Sound is a form of energy transfer and we could define loudness in terms of the energy per unit of time or power output of the sound,but it wouldn’t give the complete picture.Sound waves travel outward like balloons expanding around their source.The sound’s power is distributed on ...
Sound is a form of energy, just like electricity and light. A sound is made when air molecules vibrate and move in a pattern called waves or sound waves. Think of when you clap your hands or when you slam the car door shut. That action produces sound waves, which travel to your ears...
Here we present sound as a new form of renewable energy for charging of these batteries to some extent. Sound energy can be converted to electric energy using piezoelectric material which exhibit piezoelectric effect. In our system we employ the direct piezoelectric effect.P.C Krishna Devi...
2. The sensation produced in the organs of hearing by waves of this type. See Note at ultrasound. Did You Know? The form of energy called sound is produced when matter moves or vibrates. The vibrations are transferred to another medium, usually the air, and travel through it as sound wa...
