10²⁰ molecules of an ideal gas strike a wall for one second at an angle of 30° against the normal line. The wall area is 4 cm². the molecular mass of the gas is 213.,6 x 10^-29 kg and the molecular speed is 2 x 10³ m/s. It is known that Bolztman's constant = 1.38 x 10^-23 J/K
Calculate: The change in momentum of an ideal gas molecule in the normal direction
Consider two pool balls sliding frictionlessly across a pool table. Before the collision, ball 1 slides leftward at 2.0 m/s, and ball 2 is motionless. After the ”head-on” collision, ball 1 slides leftward at 0.50 m/s. Both balls have mass m= 0.10 kg.
What is thevelocity (speed and direction) of ball 2 after the collision?
During the collision, the balls heat up slightly. How many joules of ”dissipated” energy (e.g. heat and sound energy) are generated during the collision?
Two atoms collide while moving in a dilute gas. The larger atom has a mass M₁ = 6 Daltons and a speed v₁ = 200 m/s, while the
smaller has a mass M2 = 1 Daltons. During the collision both atoms simply bounce off each other. They do not change their speeds,
but after the collision they each change their directions, bouncing in the indicated directions. Gravity can be ignored during the
collision.
A. What is the direction of the change in the momentum of the smaller atom? Use the letters from the compass rose below the figure
to specify directions.
B. Which of the following statements are true about the momenta of the two atoms?
1. The change in the momentum of M2 has the same magnitude as the change in momentum of M1.
2. The total change in the momentum of M1 and M2 must be zero.
3. The total momentum of M1 and M2 must be 0.
4. Because the angles are not the same, the collision cannot take place as described.
C. What is the magnitude of the change in momentum of M₂?
