a. Đổi 8cm = 8.10-2 m.

Áp suất do nước gây ra ở đáy bình là:

p=d.h=10000.8.10-2 = 800(N/m2)

Áp suất tác dụng lên điểm A cách đáy cốc 3cm là:

hA= 8 -3 = 5cm = 0,05 m

pA = d.hA = 10000.0,05 = 500 (N/m2)

b. Đổi 4 cm3 = 4.10-6m3

Để quả cầu gỗ chìm hoàn toàn thì ta có:

P + F = FA

=> dg.V + F = d.V

=> F = 10000.4.10-6 –8600.4.10-6

=> F =0,00 56 (N)

a, A  =  1 + 2 + 2² + 2³ +...+ 2³⁹

   A = 1.(1 + 2 + 2² + 2³) + 2⁴.(1+2+2² + 2³)+...+2³⁶(1+2+2²+2³)

   A = 1.15 + 2⁴.15 +...+ 2³⁶.15

   A = (1 +2⁴ +...+2³⁶).15 chia hết 15 ( do 15 chia hết 15)

 Vậy A chia hết 15.

b, T = 125⁷ - 25⁹ 

    T = (5³)⁷ - (5²)⁹

     T = 5²¹ - 5¹⁸

    T = 5¹⁸(5³ - 1)

    T = 5¹⁸.124 chia hết 124 ( do 124 chia hết 124)

 Vậy T chia hết 124
