Vì trọng lượng của vật tì lệ với khối lượng của nó: P = 10m (một vật khối lượng 1kg có trọng lượng 10N), nên trên bảng chia độ của “cân lo xo” đáng lẽ ghi 1N; 1,1N; 1,2N;…, thì có thể ghi 100g; 110g; 120g … Như vậy dùng lực kế có thể xác định được khối lượng.

Fleeting has over four years under the roof of the school passed loved one, so that now the sad memories of school days fun is about to lapse. The school is still there, still quietly watching every game so we were Flood Study, with children playing and walking on the path of learning.
 
         From a distance, the school was put on her as a pale yellow shirt, but when sunlight to make shirts that become more vibrant. Orange roof mixed with dark pink color of the walls to create a colorful landscape. When approaching, we will see soon the words: "School Nguyen Van Huong" is made of marble. Though many years have passed, suffered so much rain, how the hot blazing, so that the school does not change how. the gray iron gates always reach out and expand as the arms of a mother always ready to greet the beloved child to school. for me, the throne this field is not magnificent and majestic like a castle but remains simple but solemn and full of friendly features incredible. the grounds were paved with knitting, you know, where we could run the put without fear like that slip. Two bat widespread verdure, shade made for students waiting for their parents. the flying bird from the tree landed on the waiting chirping early morning sunshine his sun. Customers bench long ranked near the classroom for us to sit and talk with each other after each lesson stress, fatigue. the grounds were also where the students and teachers living together in celebration salute the flag. Construction corridor-shaped U. Along the corridors, classrooms are decorated with funny pictures and cute. The mobile bookcases Rector place for children to be reading the book very interesting and attractive. Each classroom is decorated with many creative and idiosyncratic of each class. Classes are filled with plants hanging suspended over the windows, decorative layer, the flowers and fish shapes on the wall to create a colorful picture and for the school to strangely familiar.

vậy là về sau lại khong có quà

Tôi nghĩ rằng công thức là n2n2.

Định nghĩa p ( n ) : 1 + 3 + 5 + ... + ( 2 n - 1 ) = n2p(n):1+3+5+...+(2n-1)=n2

Sau đó p ( n + 1 ) : 1 + 3 + 5 + ... + ( 2 n - 1 ) + 2 n = ( n + 1 )2p(n+1):1+3+5+...+(2n-1)+2n=(n+1)2

Vì thế p ( n + 1 ) : n2+ 2 n = ( n + 1 )2p(n+1):n2+2n=(n+1)2

Sự bình đẳng trên là không chính xác, do đó, hoặc công thức của tôi là sai hoặc bằng chứng của tôi về hàm ý là sai hoặc cả hai.
