Масса протона 1,0073 а.е.м ., масса нейтрона 1,0087 а.е.м ., масса ядра трития 3,017 а.е.м.

Электрический кипятильник за 11 мин 12 с нагревает 2 кг воды от 200С до кипения. Определите сопротивление R нагревательного элемента кипятильника, по которому протекает электрический ток силой 5 А, если на нагревание расходуется 80% выделившейся энергии. Удельная теплоемкость воды с=4200 Дж/(кг∙0С)

These days people travel a lot. They travel at home and abroad. They went to see new places and to meet new people. Sometimes they travel on business, but ofter they go to places for holidays. In sumer a lot of people like to go to the sea or stay at the lake or near the river. There they can enjoy swimming, boating and fishing and stay in the sun. In winter peple sometimes go to the mountains to sky. It is always nice to be in the forest. Forest, lakes, seas and mountains are very beautiful places. People often make pictures of the places they visit and show them to their friends. When people go abroad they usually visit interesting places, castles, old towns, and museums. People travel by plane, by train, by car or by sea. Travelling can be very pleasant or not very pleasant but it is usually interesting.
