There are a lot of different professions in this world. Some of them is more suitable for men, some of them is suitable for women but today due to gender equality they are no longer so divided.
However, certain professions remain suitable mostly for men since they are considered physically hard, harmful or even dangerous.
Объяснение:My name is Natalia. I’m 15 years old. I study in the 9th grade of the state secondary school. At the moment I’m facing an important period of life when I need to choose my future profession.
Стрела поднимется на высоту 7,2 метров.
Объяснение:
Исходные данные: V0 (скорость, с которой стрела вылетела вертикально вверх) = 12 м/с; m (масса стрелы) = 100 г = 0,1 кг.
Справочные данные: g (ускорение свободного падения) = 10 м/с2.
Высоту, на которую сможет подняться стрела, можно будет вычислить с закона сохранения энергии: Eп0 + Ек0 = Еп + Ек; 0 + Ек0 = Еп + 0.
m * V^2 / 2 = m * g * h.
h = m * V^2 / (2 * m * g) = V^2 / 2g.
Произведем расчет: h = 12^2 / (2 * 10) = 7,2 м.
ответ: Стрела поднимется на высоту 7,2 метров.
