рис. 3.10​

jeff woke up late. the house was very quiet and jeff that he was alone there. he got up and headed to the kitchen. there nobody in it but he felt the delicious aroma of fresh baking. a large bowl of doughnuts was on the table. it covered with a white kitchen towel but jeff could not resist it and pulled out a doughnut. when he was consuming his one, his grandmother appeared at the doorway. she light working trousers, a t-shirt, and an old straw hat. jeff guessed that she had been working on roses, in the front garden. “fine, you up at last! ” said granny, “but why are you still undressed? go and wash and get dressed immediately! ” jeff remembered that granny had always been very strict about the morning routine. she never allowed her grandchildren to look untidy or avoid brushing their “ok-ok, just a second,” laughed jeff picking up another doughnut and retreating through the other door. “i _will back as soon as i am ready.”

мощность электровоза n=800000*0,8=640000 вт. n=f*v; f=n/v=640000/20=32000 (h)=32 (kh) (72 км/ч=20 м/с)

sina/sin b=sin x/sin b1; sin x=sin a*sin b1/sin b= sin 40*sin 20/sin 24=0.6428*0.3420/0.4067=0.5405 b1=33 градусов приблизительно. точнее можна если использовать данные за таблицей брадисса.
