Question

5. Сильное давление способствует вывести тело на поверхность. Давление -это мера силы, с которой одно тело действует на поверхность другого. Почему лыжник не тонет в снегу?​

Answer 1

Ответ:

из-за большой площади, которую создают лыжи. у лыж больше площади, нежели у ботинок и из-за этого давление, которое создаёт человек в лыжах мало и он не провалиться

Answer 2

Why doesn't a skier drown in the snow?

When it comes to the question of why a skier doesn't drown in the snow, the answer lies in the concept of pressure. Pressure is the measure of the force with which one object acts on the surface of another object. In this case, we can consider the pressure exerted by the snow on the skier's body.

Snow is made up of tiny ice crystals that are loosely packed together, creating a lot of air space between them. This air space is what allows a skier to stay afloat on the snow without sinking or drowning. When a skier stands on the snow, their weight is distributed over a larger surface area due to the contact between the skis and the snow. This distribution of weight reduces the pressure exerted by the skier on the snow, preventing them from sinking.

The air trapped within the snow also plays a crucial role in keeping the skier afloat. The air acts as a buoyant force, counteracting the downward force of gravity. This buoyant force helps to support the skier's weight and prevents them from sinking into the snow.

In summary, the combination of the loosely packed structure of snow and the presence of air pockets within it allows a skier to stay on the surface without sinking or drowning. The distribution of weight and the buoyant force provided by the trapped air help to counteract the downward force and keep the skier afloat.
