Two particles with the same mass of 11 kg are involved in a completely inelastic head-on collision. Before the collision both particles have the same speed of 3 m/s. Which statement below describes the velocities of the particles after the collision? One of the particles continues at 3 m/s, and the other reverses direction and moves at 6 m/s. Each particle's speed is still 3 m/s, but each has reversed its direction. There is not enough information to determine the velocities after the collision. One of the particles continues to move at 3 m/s, while the other particle is at rest. Both particles have zero velocity.

Which of the following are properties of mechanical waves? check all that apply ⭕️ particles of the medium move back and fourth, but do not move with the wave. ⭕️ the particles of the medium always move parallel to the wave motion. ⭕️ wave motion begins with a disturbance in the medium. ⭕️ waves transport energy from a source outward, away from the source.

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
