What is mean by kinetic energy? Kinetic Energy: Mechanical energy is comprised of different contributions. These are largely the potential energy and the kinetic energy. Energy is a scalar quantity of unit, the jouleJ. The availability of energy enables work to be done on or by a system, su...
What Does Potential Energy Mean? Potential energy is energy held by an object that has yet to be released. Potential energy is often due to an object's height in a gravity field, electric charge, or stresses within the object. It is often referred to as "stored energy" or classified by...
NASA launches a satellite into orbit at a height above the surface of the Earth equal to the Earth's mean radius. The mass of the satellite is 670 kg. (Assume the Earth's mass is 5.97 1024 kg and its An object weighs 1000 N at the Earth's surface. What is the gravitat...
Mechanical watches come in three varieties – mechanical, automatic, and automatic mechanical. All three have a mainspring as a power source that needs to be wound, and the difference lies in how you wind them. MECHANICAL WATCHES A mechanical watch can only be wound using the crown. This is...
What does it mean by dimension in the context of relativity? Can energy be converted into mass? If yes, then how? While solving numerically, how do we decide that we have to apply the conservation of energy? Is the energy that any mechanical device "wastes" destroyed? Explain. ...
How is energy converted from potential to kinetic (and vice versa) when objects move inup/down, back/forth harmonic motion?How is energy conserved? What does this really mean?How does friction belong in any conversations about energy?How do power, work, time, applied force relate to ...

member为混淆词,与membrane形似。定位到第三段“…amplifyand transmit the vibrations to the oval window,a membrane on the surface of the cochlea,the organ of hearing”可知,membrane为耳蜗表层的一种东西,并且能放大并传播震动。根据上下文,只有“薄膜”的含义最能体现这种功能。故本题答案为C。 The geology...
What Does CNC Mean? CNC stands for Computer Numerical Control. It refers to the use of computers to automate the control of machine tools like mills, lathes, drills, and cutters. In a CNC system, engineers create a 3D CAD model of the part. This design is then converted into G-code vi...
