NiMH batteries must be charged first. The charge won't last as long as an alkaline battery but they can be recharged 100's of times. They have a slightly lower voltage (1.2 instead of 1.5) and should work fine in many devices. For an electronic device, you may see a low battery indicator because of the lower voltage.
they reduce its contact to moisture and make th emetal thin instead of fat because it will make it overwieght
No, the Bohr model does not work for all elements. It accurately describes the electronic structure of hydrogen and other single-electron systems, but it fails to explain the behavior of multi-electron atoms. Instead, a more complex quantum mechanical description, such as the Schrödinger equation, is required to accurately describe the electronic structure of all elements.
safety (too keep it from picking up contamination from bacteria, physical contamination like dirt, chemical contamination, etc...) to keep it from breaking (like eggs) to make it easier to sell (a can of soup instead of a barrel of soup)
Whether an element is a metal, nonmetal, or semimetal. Elements around the zig zag are semimetals Elements to the left of the zig zag (and the majority of elements) are metals Elements on the right of the zig zag are nonmetals
10 percent of students go out instead of use electronic devices
the device may not work
AAAA batteries are commonly used to power very small electronic devices such as computer styluses, penlights and laser pointers. About 4 centimeters long and weighing in at only 6.5 grams, AAAA batteries are small enough to easily fit inside such devices. Most devices use AA or AAA batteries instead, so AAAA batteries tend to be slightly harder to find. However, they are readily available at Amazon and other online stores, and they are made by Duracell and Energizer, among other battery manufacturers.
Shared output devices - quite simply save a company money ! Instead of (for example) having a printer attached to each computer on a network, you have ONE printer, with everyones work being stored in an electronic 'queue' ready for printing.
The concept wireless connections means that there are no cables used but instead singal frequencies are transitted through electronic devices. A good example if the Wi-Fi connection which allow devices to connect to the Internet without any cable connections.
Robotic devices were not "discovered", instead, automation has slowly evolved from simple devices to the computer controlled devices that we have today.
You can measure temperature using a thermometer.Hope this helped you xxxH x
Integrated circuits consume less power, are smaller, can be more complex in a much smaller space and are cheaper to make for similar functions than vacuum tubes.
Simply because... labour-saving devices use much less energy to operate (such as a food-mixer versus a hand-whisk. Electronic entertainment products entice (especially) kids - to spend vast amounts of time in front of a TV - or a computer screen, instead of doing more strenuous activities. Add to that - the fact that most americans drive everywhere rather than walk... and you have your answer !
A timer implemented with electronic components instead of mechanical ones. Most electronic timers are also digital, not analog (but if a display is not required a few are analog to reduce costs).

A cell is neither an output nor an input device. A cell, also known as a cell phone or mobile phone, is an electronic device that is used for communication and can perform a wide range of functions, such as making calls, sending messages, browsing the internet, taking pictures, and playing music. While it does have input and output capabilities, such as a touchscreen display and speakers, it is not classified as an input or output device. Instead, input devices are used to provide data to a computer or electronic device, while output devices display or transmit information from the device to the user.
