дано: l (длина) = 2,6м; h = 1м; коэф. трения (k) = 0,15

найти: кпд - ?

решение:

кпд = aп/аз;

fтр=kmg*cosa;

b=l*cosa;

аз = mgh+ipтр*li=mgh+kmgb;

ап = mgh;

b=√l^2 - h^2 = √2,6^2 - 1^2 = √5,76 = 2,4

кпд = h/(h+k*b) = 2,6/2,6+2,4*0,15= 0,8783

ответ: кпд = 87,8%

ответ: 2 : 1)a   2)b   3)b   4)a

объяснение:

відповідь: i love winter vacation. although much shorter than the summer, they are always fun and bright. all because winter holidays are my favorite holidays - new year and christmas. all two weeks of holiday breaks are dominated by a festive atmosphere.

usually i spend the winter holidays at home because my grandparents or other relatives come to our holidays. we all prepare for the celebration together - we decorate the house and prepare delicious meals. and then we celebrate new year with the whole family, we usually don't sleep all night.

but this year i hope that i will be able to visit the carpathians. it is a long-standing dream of mine to spend the winter holidays at a ski resort, go skiing, see the beauty of the mountains in winter.

winter holidays are a great time. too bad they end quickly and we have to go back to school again. but vivid impressions of a good time help in the difficult learning.
