Amotorcycle is travelling at a constant velocity of 30ms. the motor is in high gear and emits a hum of 700hz. the speed of sound in air is 340ms, and there is no wind. a. what is the period of the sound waves emitted from the motorcycle? b. what is the distance travelled by the motorcycle during one period of the sound oscillation? c. what is the distance travelled by a sound wave in air during one period of oscillation? d. the humming of the motorcycle is a sound that is emitted in all directions and, once emitted, it travels in the reference frame of the still air at the speed of sound in air. consider the emitted sound that is moving directly out in front of the motorcycle

The velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
