Answer:
B. The frequency increases (gets higher) as the wavelength size will decreases (get shorter).
Explanation:
Speed of Light = Wavelength times Frequency
c = λν
We know that wavelength and frequency are inversely proportional; if frequency increases, energy increases as well but wavelengths decrease.

~orbits our Sun
~frozen gases, rock and dust
~may have brought water to Earth
~dust and gases form a tail that stretches away from the Sun
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.

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.
Answer:
a.
