Um ebulidor de resistência elétrica igual a 75,0W está envolto por 0,20 kg de gelo a 0 ºC. Os terminais do ebulidor são conectados a um gerador que fornece uma corrente elétrica de intensidade igual a 2 A, durante 1,4 minutos. Considere que toda energia dissipada pelo ebulidor foi integralmente absorvida pelo gelo. Considere, ainda, cágua= 4 J/g ºC e Lf(água) =320 J/g. Sobre esse evento físico, pergunta-se: a) Qual a energia elétrica total fornecida pelo gerador? b) Qual a temperatura final da água?

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
