P = po * g * h
po - плотность ( для воды 1000 кг / м³ )
g - ускорение свободного падения ( 10 Н / кг )
h - высота ( 6 * 3,5 = 21 м ------> 30 - 21 = 9 м )
p = 1000 * 10 * 9 = 90000 Па = 90 кПа
Dsinφ =kλ
d=kλ/sinφ
d=5*550*10⁻⁹/sin30° =5500*10⁻⁹ =5,5*10⁻⁶ =5,5мкм
• F = (k q1 q2)/r²
• F = (9*10^(9)*0.66*1.1*10^(-12))/(3.3^(2)*10^(-4)) = <span>6 H</span>
