How are mechanical waves defined?(1 point)
They are waves that are generated by humans, rather than naturally.
They are waves that involve matter, rather than energy, moving from one place to another.
They are waves that are able to pass through a vacuum.
They are waves that require some form of matter as a medium.
Where do sound waves travel faster?(1 point)
through denser materials, because the molecules in a tightly packed medium collide more frequently

Please note that I cannot assist you with time-sensitive matters as I am an AI and may not respond immediately.
I will assist you in answering the questions one by one:
1. A ringing alarm clock is put under a glass jar. The air is slowly removed from the space around it. What will happen as the air is removed?
To answer this question, you need to understand how sound waves travel through air. Sound waves are mechanical waves, which means they require a medium, such as air, to propagate. As the air is removed from the space around the alarm clock, the medium through which the sound waves can travel is reduced. This will cause the sound waves to travel less effectively, resulting in the clock becoming quieter. Therefore, the correct answer is "The clock will slowly become less visible, until you can only hear it."
2. How are mechanical waves defined?
In order to answer this question, you need to know the definition of mechanical waves. Mechanical waves are waves that require some form of matter as a medium for propagation. They involve the transfer of energy through the motion of particles in the medium, rather than the particles themselves moving from one place to another. Therefore, the correct answer is "They are waves that require some form of matter as a medium."
3. Where do sound waves travel faster?
To determine where sound waves travel faster, you need to consider the properties of the medium. Sound waves require a medium to propagate, and the speed of sound is influenced by the density of the medium. In denser materials, such as solids, the molecules are tightly packed, leading to more frequent collisions and a faster propagation of sound waves. Therefore, the correct answer is "through denser materials, because the molecules in a tightly packed medium collide more frequently."
4. The retina of the eye has rods and cones which play a crucial function in sight. Which statement explains how rods and cones work to help us see things?
To understand how rods and cones help us see things, you need to know their respective functions. Rods are photoreceptor cells that are sensitive to light and primarily detect black, white, and shades of gray. Cones, on the other hand, are responsible for color vision and are sensitive to different wavelengths of light. The brain then processes the information from rods and cones to create the perception of color. Therefore, the correct answer is "Rods detect light; cones detect green, blue, and red light; and the brain combines the three colors."
5. The American flag flies on a black flagpole. Light from the sun hits the flag and the flagpole. How is it that you can see the blue, red, and white colors of the flag and the black of the flagpole?
To understand why you can see the colors of the flag and the black flagpole, you need to consider how light interacts with objects. Objects appear a certain color because they absorb some wavelengths of light and reflect others. In the case of the American flag, the red stripes reflect red light and absorb other colors, the blue square reflects blue light and absorbs other colors, and the white stripes and stars reflect all wavelengths of light. The flagpole, being black, absorbs all wavelengths of light and does not reflect any color. Therefore, the correct answer is "Red stripes reflect red and absorb all other light, as does the blue square with blue; white stripes and stars reflect all wavelengths; and the flagpole absorbs all wavelengths."
