a studentistrying to design an artifical eardrum fo their science fair project. they made their eardrum hollow to cut down oncost and weight. when they tested howlong it took to test the subject tohear deep, they found that their control ear drum made outof wood did better than their created one. the temperature that day wa 98 fahrenheit.
determine which statement supports the students findings.
a.the created eardrum performed worst because sound travels faster in solids due to large distance between the particals
b. the created eardrum performed worst because sound travels faster in solids due to the small distance between the particles.
c.the created eardrum performed worst because sound travels slower in air due to the small distance between the particles.
d.the created eardrum performed worst because sound travels slower through air in high temperatures due to the particles moving slower.

they know that tsunamis,or ocean waves with a very large wave amplitude, happens after anther event, such as an earthquake or landslide has dramatically shifted the earths crust and therefore the water above that crust.while difficult to see the amplitude and wavelength of the individual waves while they are far out at sea, we can see how large they are as they get into shallower areas as they approach the shoreline. based on the model and explanation, how does an earthquake cause tsunamis?
A. an earthquake seismic wave provides mechanical energy to the ocean. as energy is added the amplitude of the wave is increased.
B. as the earthquake vibrates more waves are created. more waves means that there is less space between them decreasing the wavelength. because amplitude is inversely related to wavelength, this that the waves must be less energetic.
C. as the earthquake creates more waves the frequency is increased. because amplitude is directly related to frequency, the amplitude is also increased.
D. an earthquake seismic waves overlap and build upon each other as the earth continues to shake. as the earth shakes more, the amplitude of the wave increases.

The prompt above is describing what celestial body?
A) asteroid
B) comet
C) meteor
D) meteoroid
Answer:
B comet
Explanation:
The prompt above is describing what celestial body comet.
What is comet?Comets are large objects made of dust and ice that orbit the Sun. Best known for their long, streaming tails,
these ancient objects are leftovers from the formation of the solar system 4.6 billion years ago.
Comets are mostly found way out in the solar system. Some exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt.
We call these short-period comets. They take less than 200 years to orbit the Sun.

based on the table and your knowledge about waves, what can you conclude about the wavelength of mechanical waves compared to electromagnetic waves?
A. Mechanical waves have greater amplitude
B. Mechanical waves tend to have longer wavelength
C. Mechanical waves tend to have shorter wavelength
D. Mechanical waves travel faster than electromagnetic waves
(please be certain about your answer)
Answer:
The correct answer is option B) Mechanical waves tend to have longer wavelengths.
Explanation:
Before we begin, let's clarify what these two types of waves are.
Both electromagnetic waves and mechanical waves are classified by their ability to transmit energy in empty space.
Electromagnetic waves are capable of doing that, but mechanical waves are not.
The light waves that reach our planet are an example of electromagnetic waves.
On the other hand, mechanical waves need a medium to be able to move energy, it is not the same as with electromagnetic waves that are capable of transporting it on their own.
An example of a mechanical wave is sound. Sound is not capable of traveling in empty space.
This leads us to the conclusion that Mechanical waves tend to have longer wavelengths.
Which best describes a force?
A. a vector with magnitude and direction
B. a vector with speed and strength
C. a vector with direction only
D. a vector with strength only
Answer:
D is the answer
Explanation:
The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance gain energy during a change of state. Before the change, the atoms are close together and cannot slide past one another. After the change, the substance can fill its container.
A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
Which arrow represents the change of state described above?
L
M
N
O
Answer:
L, solid to gas
Explanation:
Both gas and liquid have atoms that can slide past each other, where as, solids have atoms that vibrate in place. The paragraph states that, "Before the change, the atoms are close together and cannot slide past one another.." meaning that the atoms in the substance will be able to slide past each other after the change, and that the substance was a solid before the change. Look back in that text again and you'll find that it also says, "After the change, the substance can fill its container.." meaning that the substance can move freely within its containment system, and that the substance is gas. There was energy added to the electrons in this substance.. there are a few ways of doing that, but the process in which this situation does it is called "sublimation." Sublimation is a phase change where a solid has energy added to it and skips straight into the gas phase with no liquid phase in between. The arrow in the diagram labelled "L" is pointing from solid to gas, making this the answer.

L

KE 1/2mv^2 is a for kinetic energy (KE) in terms of mass, m, and the velocity, v, of a moving object. Which choice shows a correct way to express the mass in terms of the kinetic energy and velocity?
A. m=2KE/v^2, where v≠0
B. m=KE/2v^2, where v≠0
C. m √2KE/v, where v≠0
D. m= √KE/2v, where v≠0
Answer:Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
energy = (1/2)*m*(v^2)

A horse pulls a 1500 kg wagon and accelerates it .5 m/s/s. How much force is the horse applying to the cart?
(Force = mass × acceleration)
Your answer:
Answer:
750 force
Explanation:
I have never worked with force but I can guess using the formula. 1500, which is the mass, multiplied by the acceleration, 0.5, would equal 750 force, if being applied by the equation listed, Force= mass×acceleration
