Which sentence explains why the walls sometimes vibrate in a room when the sound is coming from a projector?
O Sound waves CANNOT travel through different types of mediums. Sound waves can only
travel through gas. When the particles in the air collide with the particles in the wall, the
energy stops moving.
Sound waves can travel through different types of mediums; like gas and solids. Particles in
the air collide with the particles in the wall to transfer the sound energy from the air to the
walls of the room.
O Sound waves CANNOT travel through different types of mediums. Sound waves can only
travel through liquids. Sound isn't making the walls vibrate it is the radiant energy from the
light waves that makes the walls vibrate.
Sound waves can travel through different types of mediums; like gas and solids. Particles
carrying sound energy from the projector leave the projector and enter the walls of the room.
These particles entering the walls causes the walls to vibrate.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
