Как я провел летние каникулы
Весь список топиков на тему «Мои каникулы / My vacation» смотрите здесь
I think summer is the best season of all because it is warm, the nature is beautiful and we have great opportunities for rest. Summer is a time of holidays. We can go anywhere, spend our time near a river or a lake on fresh, green grass, swim in warm water, or climb mountains, play different games, ride a bicycle and so on.
I spend my summer holidays at my granny’s. There are many things there to do. What I did most of the time - I swam in the sea and sunbathed. Sometimes I made a fire with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other, and did everything we wanted. I also got used to walk alone in the forest.

Объяснение:
Дано:
m = 186 мг = 186·10⁻⁶ кг
I = 3 A
k = 9,32·10⁻⁸ кг/Кл
t - ?
Закон Фарадея:
m = k·I·t
Время:
t = m / (k·I)
t = 186·10⁻⁶ / (9,32·10⁻⁸·3) ≈ 665 с
или t = 11 мин 5 с
