1. Если работа двигателя будет равна работе силы трения, то скорость не изменится. Если работа двигателя больше работы силы трения, то скорость будет увеличиваться.
2.Сила архимеда будет больше силы тяжести ,а когда они сравняются пузырек будет двигаться равномерно. ответ:да,совершает.
3.
Дано:
F=5000Н
s=1000м
Найти:А
A=F*s
A=5000Н*1000м=5000000Дж=5МДж
ответ: 5МДж.
4.
1) 20 кН - 4 кН = 16.000 Н - сила, действующая на автомобиль с включённым двигателем.
2) А = 16.000 Н * 20 м = 320.000 Дж = 320 кДж.
(По формуле механической работы, A = Fs).
ответ: А = 320 кДж.
5.
Дано:
P=2кН=2000Н
h=2м
Найти:
A-?
A=Fh
A=2000Н*2м=4000 Дж=4 кДж
ответ: да ,совершает.
