Last summer I went to the Black sea with my parents. We stayed there for a fortnight. I went swimming every day. The weather was wonderful all the time, the water was warm and clean. We bathed and watched small fishes and jelly fish in the water. Sometimes we saw sea stars or sea shells there. Once we even saw a dolphin. We often sat on the beach and watched ships sailing in the distance or looked at numerous seagulls gliding over the sea. We ate ice-cream and fruit on the beach and lay in the sun. I had a nice tan by the end of our rest. I made a lot of friends and we played volleyball on the beach together. Every morning we had nice breakfast and a small run along the coast. We saw amazing waterfalls and visited a mountain lake. My days were full of different events and on returning back home in the evening I was exhausted but slept with a smile on my face. In a word, I had a wonderful time, and unforgettable experiences this summer. Next year I will certainly go to the seaside again.
летом я ездила на Черное море с моими родителями. Мы были там две недели. Я ходила каждый день плавать. Погода была замечательная все время, вода была теплой и голубой. Мы купались и смотрели рыбок и медуз в воде. Иногда мы видели морских звезд или морских ракушек. Однажды мы даже видели дельфина. Мы часто сидели на пляже и смотрели, как корабли плывут в отдалении и смотрели на многочисленных чаек, скользящих над морем. Мы ели мороженое и фрукты на пляже и загорали. У меня был красивый загар к концу нашего отдыха. Я нашла там много друзей и мы играли в волейбол на пляже. Каждое утро мы завтракали и потом совершали маленький пробег вдоль побережья. Мы видели красивые водопады и побывали на горном озере. Мои дни были полны разных событий и возвращаясь вечером домой, я была усталой, но спала с улыбкой на лице. Одним словом, у меня было там прекрасное время и я получила незабываемые впечатления. В следующем году я обязательно поеду снова к морю.
2. In an insulator, electrons are too tightly fixed by chemical compounds to be able to move, and the material normally and does not conduct electricity.
3. Opposite charges thus experience the attracting forces, while like charges are pushed aside.
4. The force is proportional to the product of the charges and inversely proportional to the square of the distance between them, this ratio is known as Coulomb's law.
