Why do car tires protect you from lightning strikes?

Why do car tires protect you from lightning strikes?

•Car tires do not protect you from lightning strikes. Although the rubber in a tire acts as an insulator at low voltages, the voltage in a lighting bolt is far too high to be stopped by tires or air. 

•No matter how thick your tires are, they don't stop lightning, according to scientists.

•A study states that inside a car can be a safe place to wait out a lighting storm, but it's not because any materials are blocking the lightning.

•Rather, if the car is struck by lightning, its metal frame redirects the electrical current around the sides of the car and into the ground without touching the interior contents. 

•The ability of a hollow conducting object to protect its interior from electrical fields and currents is one of the fundamental principles of electromagnetics. 

•Such an object is called a Faraday cage. For this reason, riding around in a convertible, on a motorbike or on a bicycle during a lightning storm is a bad idea, no matter what kind of tires it has. 

•If you are in a fully-enclosed metal vehicle, you should be protected from the lighting by the Faraday-cage effect.

•However, you should still park the vehicle and wait out the storm since a lightning strike can blow out your tires or blow out your vehicle's electronic control circuits, potentially causing you to crash if you are driving.

•If you are riding in a convertible or roofless vehicle, on a motorbike, or on a bicycle and are caught in a lightning storm, you should quickly seek out the nearest shelter. 

•If a building, tunnel, or other large sheltering structure is not readily available, seek out a low point in the terrain away from water, away from isolated trees, and away from other tall structures (e.g. windmills, power-line towers).

Hyper Automation (New Technology)

Automation is nothing but an amalgamation of two super technologies of this error RPC and machine learning understanding the automation mechanisms and how it is controlled and coordinated using machine learning MBA main Circus of the screen in the year 2020 automation is employed to have a major macroeconomic implication on the market hence top companies need to give up for this convergence in demographic shapes for now company Wipro and Infosys are experimenting with this technology but other companies are not very far behind..

How ASPs works?

By
The Web and the Internet began to really heat up and receive significant media exposure starting around 1994. Initially, the Web started as a great way for academics and researchers to distribute information; but as millions of consumers flocked to the Internet, it began to spawn completely new business models. Three good examples of innovative models include:   • Amazon - Amazon (which opened its doors in July, 1995) houses a database of millions of products that anyone can browse at any time. It would have been impossible to compile a list this large in any medium other than the Web.   • Ebay - Online auctions make it easy and inexpensive for millions of people to buy and sell any imaginable item. It would be impossible to do this at a reasonable cost or in a timely manner with any medium other than the Web.   • Epinions - Thousands of people contribute to a shared library of product reviews. One of the Web's greatest strengths is its worldwide view a...

WHY DO WE SLEEP AND DREAM?

By
•We spend about one-third of our lives sleeping.  •Why do we invest so much time in sleep?  •The most straight forward answer is that, sleep is restorative, and it replenishes the body's energy stores.  •However, intense neural activity during rapid eye movement (REM) sleep, the stage in which most dreams occur, suggests there may be more to the story.  •One theory, which by far has the largest body of evidence, is that sleep plays a critical role in learning and consolidating memories.  •It is probably why infants and toddlers need up to 14 hours of sleep a day, with half of it spent in REM sleep.  •In adults, dreams may also play a role in brain plasticity and learning, which is why sleep-deprived adults perform worse in memory tests and tasks.
