When you are near the stage, you can hear the music the loudest. When you are near the middle or the back of the field, you can still hear the music, but less loudly. When you are getting cotton candy from the concession stand, you can't hear the music at all. Why can't you hear the music at all when you're at the concession stand?

Question 14
14.

Question 15
15.

Billie ran a 100-meter dash at her school's most recent track meet. The race course ran in a straight line. Her coach measured Billie's distance covered over each second. The results are in the graph below.
Part A: In terms of velocity and speed, from this graph, you can detect ____________ because displacement _____________.
only Billie's speed
only Billie's velocity
both Billie's speed and her velocity
wasn't accounted for
was affected due to the curve in the course
was maximized because the course ran in a straight line
Billie started the race going as fast as she would go during the entire race, slowed toward the middle of the race, and slowed even more dramatically toward the end of the race.
Which TWO of the following statements BEST describe one of the differences between transverse and longitudinal waves?
When longitudinal waves disturb particles, those particles move parallel with the wave, but when transverse waves disturb particles, those particles move perpendicular to the wave.
Transverse waves need a medium to continue, while longitudinal waves don't need a medium.
Transverse waves have crests and troughs, while longitudinal waves have compressions and rarefactions.
Transverse waves are always light waves, while longitudinal waves are always sound waves.
When transverse waves disturb particles, those particles move parallel with the wave, but when longitudinal waves disturb particles, those particles move perpendicular to the wave.
Longitudinal waves don't disturb the particles they pass through, while transverse waves disturb particles that move at a right angle to their pattern.
Look at the following pictures.

The rock resting on the picture on the left, and the fact that it would remain at rest until the man in the picture on the right attempted to move it, is an example of __________, which is detailed in Newton's __________ Law of Motion. On the other hand, the man prying the rock up from the ground in the picture on the right is an example of __________.
an unbalanced force
a balanced force
First
Third
Second
inertia
The sound waves are gradually all absorbed by the mediums between the stage and the concession stand.
Look at the crane using an electromagnet to move a car across a junkyard and drop it into a crusher.

For which TWO of the following reasons do engineers prefer electromagnets to regular magnets when designing a heavy-duty crane like the one shown above?
Since the car is metal, is it an ideal conductor for electromagnetic force, while regular magnets generally do not produce a force field.
Since regular magnets are rare in nature, it is cheaper to design and build an electromagnet than it is to search for a regular magnet to do the same job.
The weakest electromagnet has a stronger force field than the strongest regular magnet.
Electromagnets have the ability to attract, like when they lift the car, and repel, like when they drop the car, while regular magnets only have the ability to attract, and therefore would be incapable of dropping a car.
Since they utilize electricity and since their strength can be manipulated to an extreme degree by humans, electromagnets are almost always more capable of doing heavy-duty work than regular magnets are capable of doing.
Electromagnets can be turned on to picked up the car and off to release the car, while a regular magnet can't be turned on and off.
A runaway truck ramp is designed to maximize a truck's potential energy by stopping the truck on the crest of a hill.
