Проводник длиной 8 см по которому течет ток силой 50 А, переместился в однородном магнитном поле с индукцией 20 мТл и совершил при этом работу, равную 8 мДж. На какое расстояние переместился проводник, если он двигался под углом 45 градусов к вектору индукции и самому себе?

Сила АмпераF = B*I*L*sin45Работа:A = F*S A = B*I*L*sin45*SS = A / (B*I*L*sin45⁰) = 8*10⁻³ / (20*10⁻³*50*0,08*0,707) ≈ 0,14 м или 14 см

In the second half of the XX century, biological production potential of the world's oceans was seen as an inexhaustible source of seafood, especially fish, due to which it was planned to ensure food security of the inhabitants of the planet. As in the foreseeable future, expect an increase in catch and seafood production is not necessary, further increases in fish production is projected only through the development of predominantly freshwater aquaculture, and, as the international experience in this area is currently an alternative to the global fishing industry does not exist. Fish farming - one of the most promising sectors of agricultural production, which occupies an important place in the agriculture of the country as a source of raw materials and semi-finished products for the food, medical and light industrial feed products for livestock and poultry. Agricultural fishery products is of great importance for ensuring the necessary human proteins, fats and carbohydrates. Even with the current significant reduction in the consumption of fish per capita (9 kg compared to 14.5 kg in 1990), their share in the balance of meat and fish is about 40% (in the protein-year), and the overall balance of animal protein including meat , dairy products and eggs - 8%. Fish products can be used as medical, therapeutic and preventive diet. The advantages are farming fish farming in the rapid growth of fish, lower feed costs compared with farm animals. The advantage over other fish farming industries and agricultural sector is in great fertility of fish. The number of eggs produced by different species of fish, ranging from a few thousand (trout) to several tens of thousands (whitefish) and hundreds of thousands (carp). From one female carp get 500-600 thousand or more eggs, of which the following year can be grown for at least 60 tonnes of fish. Due to the high fertility for large-scale production of marketable fish can contain a small number of manufacturers. Also in conditions such as pond fish with proper selection of the locations of farms and careful monitoring of the quality of feed can be produced eco-friendly fish products. All the above indicates the merits of the agricultural and fisheries huge role in a person's life. In our country the first in the carp pond culture is. It is very easy to grow, as unpretentious and along with it has excellent taste. Recently, together with carp began to grow herbivorous fish, which allows the best use productivity ponds. Thus, high reproductive capabilities of fish, the rapid growth, the availability of broodstock fish farming at the point of consumption to quickly increase the volume of its production.

Вопросы:
1. Is fish farming one of the most promising sectors of agricultural production? 2. How can fish products be used? 3. How many eggs can one female carp produce? 4. Why can we have a small number of fish manufacturers? 5. What do the above facts indicate?  6. Our country is the 1st to cultivate carp pond culture, isn't it?  7. Is it easy or difficult to grow carp?  8. What id they begin to grow recently along with carp?  9. What contributes to increasing the volume of fish production?  10. How did the world view the biological production potential of the oceans in the second half of the XX century?
