Ответы

Автор ответа: Аноним

Ответ:

в)

Объяснен

На них будет действовать сила Архимеда

Смотри формула сила Архимеда имеет такой вид

где p - плотность жидкости, так как их все опустили в воду этот показатель одинаковый

g - ускорение свободного падение = 9.8H при всех случаях

V - обьем тела, за условием сказано что он одинаковый у в 2 шариков

С этого выходит что сила архимеда которая действует на в 2 шара - одинаковая!! (F1=F2)

переведите пожалуйста текст, очень надо

this is my last year at school, and i am very busy, in fact. i am an early riser. on week-days the alarm-clock wakes me up and my working day begins. it is seven o'clock. in spring or early autumn i usually run to the window and open it wide to let the fresh air in. the sunshine and fresh air set me into cheerful working mood. sometimes i do my morning exercises, but sometimes i just take a walk and go to school on foot. in winter it's different, of course. i am not so quick to leave my bed. but all the same, it's time to get up and start getting ready for my working day. i do my bed and go to the bathroom. i take a shower, brush my teeth. then i go to the kitchen and have breakfast. while i am having breakfast, i switch on the radio and listen to the news. breakfast, asdoctors say, must be the most substantial meal of the day. so, for breakfast i usually have eggs and sausage or cheese sandwich and a cup of tea or coffee. sometimes i like to have some porridge. after breakfast i leave for school. it takes me fifteen minutes to get to school by bus, and a bit longer if i go on foot. on my way to school i often meet my classmates and we go together. my classes begin at 8.30. six or seven lessons a day is my ordinary timetable. so i stay at school i till 2 or 2.30. we study many subjects: history, geography, mathematics, chemistry and physics. but my favourie subjects are the english and russian languages and natural sciences as maths and chemistry are most difficult for me. when classes are over i go home. i walk home with my friends and we have a nice chat about school and a lot of fun. after midday meal and some short rest i do some cleaning or shopping just to help my mother and then i go to the reading-room to prepare my homework. i stay there for three or four hours. i am found of english and writing reports and compositions. i do well in these subjects and it gives me a lot of pleasure to get ready for there lessons. there is practically no time left. but nonetheless i attend a swimming pool twice a week and, on saturdays, the english club. here i have additional practice in the english language. we sing songs, recite verses and poems, se video films or meet some foreign guests who speak english. sometimes we do some performances, too. i take part in drama performances and sing. after the concert we dance. late in the evening, i say (goodnight) to my parents and go to bed. as a rule, it is about midnight. that is my usual week-day when i am, really, as busy as a bee.
