Question

Помогите пожалуйста решить задачи по физике. Очень надо

Answer 1

3-63

$F = mg$

$m = frac{F}{g} = frac{392}{10} = 39.2 : kg$

3-65

$m = Vp$

$m = 750 times 0.025 = 18.75 : kg$

3-67

$m1 = 1 : kg \ m2 = Vp = 0.005 times 800 = 4 : kg \ m = m1 + m2 = 5 : kg \ p = n = mg = 50$

3-64

$F = mg \ m = frac{ F }{g} \ m = 4.9 : kg$

3-66

$P = mg \ P = Vpg \ P =0.01125 times 700 times 10 = 78.75 :$
