Объяснение:

Вредные звуки-чрезмерный шумовой фон, искусственные техногенные звуки, инфра и ультразвук, бранная и нецензурная речь(это как для кого) а также музыка определённых музыкальных направлений.                    

Полезные звуки-все которые тебя успокаивают. Эти звуки тоже полезные: пение птиц,стрекотания насекомых,шум листвы,журчание ручья этим звуком иногда лечат.

Некоторые душевные расстройства лечатся пением птиц.

Пение дроздов, соловьёв,скворцов и жаворонков снимают стрессовые нагрузки, дают вдохновение.

Звуки капель дождя японские учёные используют в лечение некоторых болезней.

Классическая Музыка успокаивает усталого раздражённого человека.

Задача 1:

var a,r: double;

begin

writeln('Введите сторону квадрата a');

readln(a);

writeln('Введите радиус круга r');

readln(r);

writeln('Площадь фигуры: ',a*a-Pi*r*r);

end.

Задача 2:

var a, b, c, D, x1, x2: real;

begin

writeln('Введите A, B, C');

readln(a,b,c);

D:=b*b-4*a*c;

if D>=0 then

 begin

  if (sqrt(D)=0) then

   begin

    x1:=-b/(2*a);

    write('Один корень ',x1:0:2);

   end

  else

   begin

    x1:=(-b-sqrt(D))/(2*a);

    x2:=(-b+sqrt(D))/(2*a);

    write('Первый корень: ',x1:0:2,' Второй корень: ',x2:0:2);

   end

 end

else write('Корней нет');
