Question

Определить импульс силы, с которой действует на стенку молекула водорода за время одного удара если она летит нормально к стенке со скоростью 800 м/с

Answer 1

Примените второй закон Ньютона: Импульс силы равен изменению импульса тела: F*dt=d(m*v)

Answer 2

Calculation of the Impulse of Force on a Hydrogen Molecule

To determine the impulse of force acting on a hydrogen molecule as it collides with a wall, we need to use the formula for impulse:

Impulse = Force × Time

In this case, the force is the force exerted by the wall on the hydrogen molecule during the collision, and the time is the duration of the collision.

Given: - Speed of the hydrogen molecule before the collision: 800 m/s

To calculate the impulse, we need to determine the force and the time of the collision.

Determining the Force

The force exerted by the wall on the hydrogen molecule can be calculated using Newton's second law of motion:

Force = Mass × Acceleration

In this case, the mass is the mass of the hydrogen molecule, and the acceleration is the change in velocity during the collision.

The mass of a hydrogen molecule is approximately 2 atomic mass units (u) or 3.34 × 10^-27 kg.

To calculate the acceleration, we need to determine the change in velocity during the collision. Since the hydrogen molecule is moving normally towards the wall, the change in velocity is equal to the initial velocity of the molecule.

Therefore, the force exerted by the wall on the hydrogen molecule is:

Force = Mass × Velocity

Substituting the values:

Force = (3.34 × 10^-27 kg) × (800 m/s)

Calculating the force:

Force ≈ 2.67 × 10^-24 N

Determining the Time

To determine the time of the collision, we need additional information. Unfortunately, the provided search results do not contain the necessary information to calculate the time accurately.

Therefore, without the specific information about the time of the collision, we cannot calculate the impulse of force on the hydrogen molecule accurately.

Please provide the necessary information about the time of the collision so that we can calculate the impulse more precisely.
