How many QR codes can be generated?
More than the atoms in the universe (estimated to be 10x10x10... 81 times). More than all the email addresses created and yet to be created....It is a really really large number. The Wikipedia article mentions that it can have 7089 numeric only characters: ie equivalent to10x10x10..... 7089 times (each character can be 0-9).There is nothing magical about QR Codes. It is just machine speak and the storage dictates how much you can write. So how many different numbers can you write if you have a paper grid with 7089 squares ?Or if you have a sheet of paper in which you can type up-to 4296 alpha-numeric characters. How many different essays can you compose ? Mind-bogglingly large (if you want to calculate, it is 45x45x45 ....... 4296 times!)This picture illustrates the point. On the right is the QR Code machine speak version of the English text on the left.
Do you really need a micro sim adapter to put a nano sim card into a Samsung Galaxy S3?
You do not need a SIM adapter to make a nano SIM card work in a micro SIM slot. However, I would definitely recommend it.If we look at some of the dimensions of the different sim cards we can see why:Source: www.te.comFrom the graphic we can already see that a nano SIM will have around 2.7 mm more slack on the long axis and around 3.2 mm on the short axis. It's also a bit thinner, but most connectors have 'springy' contact points, so I'm not going to address that here.In the most generous case, the six relevant contact points have dimensions of around 4 mm in length and a width or around 2.8 mm. If we assume that the connector makes contact in the middle of each SIM contact, that leaves us with around 2 mm of wiggle room along the long axis and 1.4mm along the short axis, where the SIM card will connect correctly. That's quite a bit less than the micro SIM slot allows! Additionally, in the worst case, SIM contact patches have the dimensions of 2 x 1.7 mm[1].So, as you can see; the amount of wiggle room a nano SIM card has in a micro SIM card slot is more than the size of the contact patches allow. If the contact patches and connector points become misaligned, your phone will likely not connect to the network anymore, because it won't be able to read the SIM's unique identifier needed to access your provider's network. In the worst case, it could corrupt (some) data on your SIM card if data was being written to your SIM card while the SIM became misaligned.If you really don't want to spend any money on an adapter, you can always cutout one from an old bank pas, or similar plastic card and use that to keep the nano SIM locked in place.Source: www.aliexpress.comFootnotes[1] All you need to know about nano SIMs - before they are EXTERMINATED
How long does the battery last in an electric car?
Way longer than many folks think.I have a 2015 Model S with the 85kWh pack. I have over 55,000 on the car, and my battery degradation is 4. I have lost 4 miles of range on a full charge. On day one my car had a max rated range of 265. It is down to 261 today.Leaf’s had problems with longevity, but those have been rectified. There are still problem Leaf’s out there though. They didn’t go back and replace everyone’s battery packs.Watch out for EVs from manufacturers that don’t actually have a long term EV strategy. VW, Toyota, Fiat - just to name a few. They have EVs, but hate that they had to make them and hate that they had to sell them. They are compliance cars available pretty much exclusively in the CARB states of the US. When a car maker begrudingly builds an EV because they have to, it won’t be anywhere near as good as a car maker that is building EVs because they believe in them long term.Also, be wary of opinions on EV’s, EV service, EV battery life, etc., from people who don’t drive EVs. Lots of people read some articles and watched a documentary on Netflix and now know enough to share opinions on the topic.Truth is, we don’t know. We don’t have EV’s with batteries that are in end-of-life cycles yet. Six years of real production, and there just aren’t enough cars to look at and draw any conclusion what end-of-life looks like for battery packs. This includes a lot of Tesla’s well over 100,000 miles, and at least one that I know of that’s approaching a quarter million miles.

Give your answer to the nearest gram. please answer and give details on how to solve. like how do i put it in the calculator and how do i go about thinking about it?
What are some examples of radio waves and their uses?
Radios and televisions are two examples.AM radio -- FM radio -- TV (non-cable) -- TV (satellite) -- police radiofiretruck radio -- ambulance radio -- sheriff's radio -- highway patrolradio -- taxi radio -- garage-door opener -- pilot's communicationpilot's navigation -- Blue tooth -- cellphone -- wireless Internet in thehouse -- iPhone -- Wifi around town -- microwave cooking -- microwavecommunication -- weather radar -- cellular phone -- GPS signals.Uses of Radio Waves :The prime purpose of radio is to convey information from one place to another through the intervening media (i.e., air, space, nonconducting materials) without wires. Besides being used for transmitting sound and television signals, radio is used for the transmission of data in coded form. In the form of radar it is used also for sending out signals and picking up their reflections from objects in their path. Long-range radio signals enable astronauts to communicate with the earth from the moon and carry information from space probes as they travel to distant planets. For navigation of ships and aircraft the radio range, radio compass (or direction finder), and radio time signals are widely used. Radio signals sent from global positioning satellites can also be used by special receivers for a precise indication of position. Digital radio, both satellite and terrestrial, provides improved audio clarity and volume. Various remote-control devices, including rocket and artificial satellite operations systems and automatic valves in pipelines, are activated by radio signals. The development of the transistor and other microelectronic devices led to the development of portable transmitters and receivers. Cellular and cordless telephones are actually radio transceivers. Many telephone calls routinely are relayed by radio rather than by wires; some are sent via radio to relay satellites. Some celestial bodies and interstellar gases emit relatively strong radio waves that are observed with radio telescopes composed of very sensitive receivers and large directional antennas.For Electrikals OnlineShopping Visit :https://www.electrikals.com/
What is the difference in using 12 volts 2 amps adapter or 12 volts 1.5 amps?
I prefer the one with higher i.e 2Amp rating.Reason: It is a rating —-> Max current it can supply. Your device draws much less current than that.Don’t confuse that it will supply that much current to your device. Higher current rating means bigger muscle —-> it can lift smaller loads too. The 1.5A adapter has smaller muscle, can not lift the loads the other one lifts.
