Questions

 

Does anything other than our moon gets eclipsed, such as stars or other planets?


 

We're using electric chargers to charge phones, torches and things. Once the product is charged does the charger switch off or does it carry on using the same amount of electricity until you switch it off.


 

Would it be practical to build a large vacuum chamber, put the clothes inside, pump the air out and therefore lower the pressure, and that makes the water in the clothes boil or evaporate off? Would the clothes survive the experiment? And would it be energy efficient?


 

When a meteor hits the Earth like the one that was supposed to have killed off the dinosaurs, it hit with the impact of hundreds or even thousands of nuclear bombs going off. Why was that? If I was to throw a large rock off the Empire State building it would make a big crater but no fire, no explosion, no nuclear reaction. Why is this?
