In materials of the same phase, or state of matter, the speed of sound tends to decrease as the density increases. Is this true or false and why?

False because the molecules of a denser substance have less inertia and move very quickly as compared to molecules of a less dense substance.

True because the molecules of a denser substance have less inertia and do not move as quickly as molecules of a less dense substance.

False because the molecules in all substances have no inertia so it does not have any effect.

True because the molecules of a denser substance have greater inertia and do not move as quickly as molecules of a less dense substance.

The force will determine the acceleration.

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
