1.How many electrons have removed from a positively charged pith-ball electroscope if it has a charge of 7.5×10^-11C?2.What is the charge in coulombs on an object that has(1)An excess of 6.25×10^19 electrons?(2)An deficiency of 1.0×10^8 electrons? 答案 1.一个电子电荷e=-1.6...
You can describe all of the interactions between the object and reference beams, as well as the shapes of the interference fringes, using mathematical equations. This makes it possible to program a computer to print a pattern onto a holographic plate, creating a hologram of an object that doesn...
The drum, charged with static electricity, can attract the toner particles. There are three things about the drum and the toner that let a copier perform its magic: The drum can be selectively charged, so that only parts of it attract toner. In a copier, you make an "image" -- in ...
You can hide a link in a clickable image, as explained in 1 – 3 below. But if you want to choose your anchor text and hide your website URL, I have bad news. You can’t hide a link to an external URL in text, whether in a Facebook post or comment. This could only be done...
The total of all possible states in which an object can exist -- for example, in a wave or particle form for photons that travel in both directions at once -- makes up the object's wave function. When we observe an object, the superposition collapses and the object is forced into one...
I have laid the foundation for success, now all you have to do is build upon it and watch it grow! I have proven to be a success time and time again. Now you can take part in this action and become what I call a "Real Estate Winner." ...
Contact electrification is a type of static electricity that occurs when two surfaces come into contact with each other and then separate. This creates an imbalance between the two surfaces, causing one to become positively charged and the other negatively charged. ...
So how does it work? This animation walks you through the process. The Basics A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions...
The waves travel until they make contact with an object, then bounce back to the source. A bat or a computer can then determine the shape and distance of the object based on this returning sound wave. Ultrasound imaging systems transmit high-frequency sound pulses through the human body. ...
