Why electric cars are not regular thing?
Range anxiety. The typical gasoline-powered vehicle has a range of about 300 miles, and can be refueled in mere minutes. The typical electric vehicle that is affordable by most consumers (i.e.
Why is glass so inert to acids?
Dat silicon dioxide. Acids react by having a weakly held hydrogen that the other part of the molecule doesn't care for much, and would really rather have a metal in its place, as metals are much more
Why are Teslas super fast off the line and yet at a certain point a non-electric super car will catch up to it?
It's pretty simple, they have instant full torque at any RPM (where most automatic cars are at ~4000RPM or 1500RPM-3000RPM if turbo boosted), however, they are not powerful motors, at least not as pow
Why are cold showers so uncomfortable compared to pools?
They're both equally unpleasant to me, but if this is the case for you, I think it's for the same reason it feels colder when wind is blowing. In a still medium (water, air), you feel cold at first, b
Why can’t we put metal objects in the microwave, yet the inside is made of metal, including the metal mesh on the inside of the door. Is the metal coated with some special paint that makes it ok to…
Electrical engineer, the answer is simple. The metal box is a conductive plane, preventing potential differences from accumulating. They discharge naturally and rapidlly The frequency of the microwave
why do lightbulbs seem to go bad only when being turned on?
The filaments in the bulb get thinner and thinner with more use. At some point they are thin enough that the surge of electricity when turning on the bulb is more than the filament can take.
Why doesn’t solid material, when it breaks simply connect back together? What kept it together that is gone now?
As soon as you break molecules apart they immediately want to stick to something, and they'll take anything that fits. For example diamonds are actually covered with a layer of hydrogen atoms, as soon
Why don’t we use microwave waves for water heaters instead of natural gas?
The speed at which a microwave works depends on the mass of the materials. That's actually a FAQ here (as in "Why does my microwave take longer to cook twice as much food when my oven doesn't?"). I ti
Why do male orgasms get more intense in relatively short amounts of succession?
Well everyone is different. Wildly so, in fact. Some people are capable of sustaining multiple, repeating orgasms of increasing intensity.
Why does water cause electronic devices (I.e. cellphones) to malfunction even after said devices have completely dried?
Unless it's distilled water, water is actually pretty dirty. It's full of little particles and sediment. Take a really close look at a glass of unfiltered drinking water and you might probably see som
