Thomas Edison
Thomas Edison invented light because he made light so why not bulbs
Willis Haviland Carrier is wrong he invented the air conditioner AC is an electrical current invented by Nikola Tesla. Thomas Edison who invented DC, used AC to make an electrical pad, killed cats and dogs to ruin Tesla because he wanted to prove it was dangerous, but DC is more dangerous.
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
Thomas Edisons contributions to science are extremely exaggerated. He invented almost nothing. His work was improvment upon already invented items. The main reason he did improve these items was to sell them for profit.
Edison invented a DC power system in the start but it had problems transmitting long distances, Tesla invented the AC power system, transformers, ac motors and generators Tesla also invented a wireless electricity supply system where you picked up your electricity through the air with a tuned antenna but he was not allowed to finish the construction of the first transmission tower because he wasn't able to meter the electricity for sale.
The reason why Katie got a detention is because she was talking and being direspectful in maths class.

She didn't do anything, she came to detention because she had nothing better to do that day.
Preventative detention is unfair because people are punished for a crime before they have a fair trial.

because you don't want detention?!
Olivia White from Lemonade Mouth gets in detention because she was skipping classes by reading a book in the janitors closet.
not really,, but if you get a detention dont even bother mowing down the punishment prefect because it will just restart,, but if you press start and then press load it will reload the last time that you saved which means you dont have to do the detention :)
